I'm an electronic technologist with more than 30 years of experience dealing with advanced electronic and computer systems. I worked in calibration labs, Air Traffic and navigation, communications and radars. I built, installed and service them for years. Electronic is what I do.
Since the last 15 years my main hobby had been audio stuffs starting with the simple and the affordable and now dealing more with the exclusive and the sophisticated side of the equation. I built some of my best sound system components from circuits, then PCB and up to enclosure design, solid state or tubes. I also collected very nice gears over the years from major players in the audio league such as Mark Levinson, Air Tight, Ayre, Audio Research, Yamamoto, Vacuum State, Borbely, name it. I think that now I know what a good sound is, at least according to my own tastes.
I built stuff mainly for me or my friends, but sometime I organize or participate in Group Buy. Over the years I built a little circle of contacts that help me in my endeavors, to find difficult to source parts, discuss circuits, etc.
This site is dedicated to my passion. Read on...
Air Tight ATC-2 Preamp, Statement tube preamp. My new toy. This particular unit is fully modified and comes with the optional premier ALPS HQPRO volume control. The preamp has several additional important upgrades, done by Roger Sheker of Audience in California. The one 12AX7 tube is replaced by a third 12AU7 tube, in order make the output impedance more manageable, and the 6X4 rectifier tube replaced by a 6CA4, for reliability and uniformity. Also, the original hardwired power cord has been replaced by an IEC socket so that any power cord can be used. Finally the jacks on the back were replaced with Cardas jacks and the interior wiring with Audience wire. I'm planning to install my own DIY LC-Audio Light phono preamp with external supply to get a phono inside. See some nice pictures on www.diyaudio.com.
Vacuum State RTP3D Preamp, Ongoing Project. I loved the SVP-2 so much that I'm building from scratch, including the two enclosures, the complete RTP3D preamp. It will have the 'D' version supply, but will still use the point to point construction of the 'C' version for the preamp itself. It is fully assembled and tested, but still have to complete some work on the enclosure.
Vacuum State SVP-2, ver2 Preamp. I've always been a great fan of Allen Wright design. Its preamplifier cookbook is a must read. This preamp is the little brother of the renowned RTP3, but single ended. It uses all of Allen's tricks to get the best result from tube circuit: HV Shunt SuperReg, best sounding Super Linear Cathode follower with FET current source, precision and matched parts for perfect RIAA correction and channel matching, great volume control using Elna switch and SMD film resistors, etc. Even the PCB design is very special, all signal traces are on the top of the board, and never cross underneath. The board bottom layer has only the GND and supply traces. This preamp has also a great phono stage section. I have to say that it matches, if not betters the Audio-Research PH5 I used to have. It is just lovely, perfectly silent. Superb preamp. See www.vacuumstate.com for the preamp description, and excellent review from HiFi+ . See also www.sixmoons.com for a great review of the RTP3D.

Digital Audio Music Server:
Mac Mini based Audio Server, My first little music server based on a small Mac Mini computer (OSX Snow Leopard, 4GB RAM, 2GHz Intel Core 2 Duo, 120GB internal HDD) with external harddrive, iTune program and database. There is a small M-Audio Firewire Audiophile DAC that is used as Firewire to Spdif interface only (it also includes a very good headphone amplifier). I'm using my excellent Yamamoto tube output DAC as music source and my iPad as remote control. I use the Remote, a free application downloaded from the Apple App Store. This application turns your Apple portable device such as iPad, iPhone or iPod Touch into a remote control for your iTunes media player. See details on www.diyaudio.com.
This excellent site explains a lot about the Mac Mini as server: www.monarchyaudio.com.
Other nice Computer audio guide: www.linkwitzlab.com.

M-Audio Firewire Audiophile Dac www.soundonsound.com
Mark Levinson ML390S Compact Disk Player and DAC, probably the best player Mark Levinson ever made, see one of the review at www.stereophile.com. It is also a great DAC with external inputs using the same expensive PCB material as the ML380S preamp, nude Vishay laser trim resistor the I/V converter, great transport (same as the ML37), etc... The original superb hi-res Mark Levinson pictures can still be seen at www.hifishock.org
Mark Levinson ML37 Compact Disk Transport, one of the best transport ever made, see: www.marklevinson.com
Upgraded in 2010 with the newest CDPRO2LF drive. The ML37 used from the start an external low jitter clock mounted on its digital In/out PCB to drive the CDPRO2 inside it. I did the same mod on the newest CDPRO2LF so it can use the ML37 own clock. See this web page for some details: www.diy-high-end.com
Mark Levinson ML36 , Matching DAC (Burr-Brown PCM1702 and upgraded CS8416). I got myself a set of ML36 boards for a project that I did. I have already the original ML36 front panel and I will use my own ML38 front control PCB (they are almost identical) to control the DAC. I'll install everything into the upcoming ML38 enclosure and I had made especially for me a custom rear plate that reproduce the original ML36 rear panel. At the end, I'll get a complete ML36, DIY at work again...see the Audio Projects.
Teac Esoteric DV-50 Universal Player used as player and transport, on of my reference sources, see: www.teac.com/esoteric
Yamaha CD-S1000 SACD CD player. Just a gorgeous machine built like a tank. It is just awaiting to be modified to transform it into a killer player and transport. With minimum modifications it can becomes a CD-S2000 with balanced outputs. The only difference between both machines is a separate transformer for the Audio section power supply and a few missing parts on the Audio output board. Both machine use the same board, so it is easy to upgrade. And just had a low jitter clock with its own supply and it becomes a superb transport.
Primare CD31 Superb CD player. With balanced outputs, fully balanced (double dac) discrete outputs. Modified with soft recovery diodes for the audio supplies and EMI filter replaced by an Ayre filter. See review at: www.stereophile.com
Pioneer DV-563 (Universal Player, modified supply and output), see the Audio Projects section
Pioneer Elite PD-65 (Used as transport)
Rotel RCD-965BX Trusty little player, used for testing for my projects
Digital to Analog Converters:
Schiit Audio Bifrost DAC Great little DAC with great sound. With the optional discrete analog stage 'Uber' using a servo without coupling caps on the output. Schiit audio may not be well known but they have great and innovative design and sold direct with prices you can't beat. This DAC uses the AKM4399 D/A converter, a sophisticated adaptive clock called 'BitPerfect', separate analog and digital discrete supplies and support USB 2.0 using a great asynchronous interface compatible 24/192. See schiit.com for details and review at: www.tonepublications.com and www.6moons.com
Yamamoto YDA-01 DAC clone (DIY) Mine is special, a reproduction of the marvelous Yamamoto YDA-01 DAC, but with Solid-State and Tube (YDA-01B) outputs into the same DAC, selectable with just the flip of a switch. It has also dual selectable digital input and DIY Ayre line filter. First of my projects to use PCB with no solder mask or copper trace plating. I call it 'Pure Copper' PCB. The bare and shiny PCB traces are covered instead with a thin layer of clear lacquer, than burn away when soldering the parts (and smell good doing so). The Solid-State output board is supplied by Shunt regulator.
The Tube output section is also slightly different. It is still using WE408A tube, but has a different CCS, different cathode loading and grid stopper for an even better sound. I love this DAC.
All internal wiring is done using Neotech Solid-core UP-OCC COPPER Wire, Teflon jacket.
See some great reviews of these DAC on 6moons, ss version review: 6moons.com-YDA-01, and the tube review: 6moons.com-YDA-01B
Yamamoto YDA-01B DAC clone I like the YDA-01so much that I built as well the tube version for me. With a custom toroid transformer, and Yamamoto Teflon tube sockets and terminal strips, M-Lytic Mundorf HV cap and ClarityCap MR output coupling cap. A few weeks back my and friends we compared this Dac with the new Meitner MA-1 (7K$), and the Naim NDX and the NAD M50 music player in a streamer/server test bed. Guest what the Yamamoto was way better than the Naim and the NAD using an other Dac, and as good as the Meitner! We also listen to some excellent hires files (192/24 bits) files from Fidelio, and the Yamamoto and Meitner were very close, with a little edge from the MA-1 part. This is how good this Dac is and considering the price difference between both dac, the Yamamoto is a steal.
Super Tube DAC with low jitter PLL clock and Tube Output, see the Audio Projects section and the original designer site see: Original Project Page (Explorer only)
SDS-Labs Tube DAC, using a pair of PCM63-K DAC chips (maybe one of the best DAC chip ever made), passive I/V conversion (using a Riken resistor) and Shunt Regulated Push-Pull (SRPP or Mu Follower) all tube output. I'm planning to use it for an upcoming music server. My own version has some improvements and modifications such as two selectable inputs (SPDIF BNC and USB, using the Hagerman "HagUSB" SPDIF-USB converter, CLC filtering on all digital IC supply pins, Oscon caps, screen ground plane, Jensen paper in oil coupling caps (and AuriCap film bypass caps), Takman carbon film resistors in the Tube section and mute relay at power-up. The supply is using custom built toroid transformers. See www.quadesl.com for details.
dAck! Original and Clone, a TDA1545-CS8414 DAC None Over Sampling, see the Audio Projects section and www.ack-industries.com for details. I use it with my headphone. Very nice sound with no fatigue.

Thorens TD124 turntable with SME3009 tonearm, Newest acquisition, a real classic. The Thorens uses an AC 4 poles induction motor, belt/idler wheel drive, 16, 33, 45 and 78 rpm, mechanically switched, pitch (using a clever "Eddy Current Brake"), platter weight 4.5 kg (steel), aluminum subplatter with clutch, manual operation. Probably one of the greatest engineered turntable ever. Designed specifically for one job only, spin records. Mounted on it was a very nice SME 3009-S2 tonearm. The Nylon knife-edge bearing was be upgraded to a CNC bronze knife bearing. Cartridge is the Shure V15VxMR MM 3mv Output, 25 µm/mN compliance, Micro Ridge Stylus and weight 6.6g. Phono Preamp is my clone Graham Slee Era Gold V. See www.soundfountain.com and www.analogue-classics.com or www.theanalogdept.com for some interesting discussions on the Thorens. For the SME 3009 and its variants, see www.analogue-classics.com again for some details.
Teres model 100, DIY turntable with Graham 2.1 tonearm and Ortofon Kontrapunkt-H MC Cartridge. This turntable is no longer available as a kit. I was able to get the acrylic platter and the bearing kit from an other user on www.diyaudio.com, see my project development on this link. My teardrop wood base is done. It is made of dried maple, laminated and ready for finishing. The wood is so nice that I will only put a clear lacquer finish. The plinth will be loaded with lead to add weight and to absorb the plinth's resonance. I have 3 diamond cones feet on order to put under the turntable. I just got for Christmas the Teres Delrin record clamp. See www.teresaudio.com for an picture of what it will be. I have my own version of Mark Kelly battery supplied Maxon motor controller already built and ready to go, see the audio project section. I'll use the new mylar tape drive using the Teres tape pulley. The motor pod is a recycled very nice sensor aluminum enclosure with a machined custom top plate that fits the Maxon motor. Finally, a DIY Schroeder tonearm is in the pipeline. I'm getting help from an other diyaudio member for the Schroeder machining. See: www.vinylengine.com and www.theanalogdept.com. Tonearm is the Graham model 2.1 tonearm, maybe one of the best unipot design, except the famous Graham Phantom II . It has all the 2.2 upgrades minus the ceramic wand (Top bearing and tungsten side weights). This arm have some of the best setup tools included and allows on the fly VTA adjustment. See a review at: www.stereophile.com. To connect the arm, that is sold without interconnect cable, I'll use the own Graham top-of-the-line IC70 cable, again one of the best tonearm cable. It is a silver interconnect with separate Teflon insulated L/R wires. It is terminated with the 5 pins DIN connector at the tonearm and RCA Bullet plugs at the other end. Cartridge is the Ortofon Kontrapunkt-H MC (0.47mV output, 12 µm/mN compliance, Nude FineLine elliptical stylus, weight 10g. See Ortofon www.ortofon.com for details and a few reviews at: www.6moons.com and www.audioasylum.com.
Michell Tecnodec turntable with Rega RB300 tonearm (with Michell upgrade TecnoWeight, VTA adjuster and record clamp). I built also an upgrade dual Speed High Capacity DC Supply and an upgrade mounting platform for the Technodec. The Platform is a laminate of high quality Birch ply, MDF and Brushed Aluminum. The RB300 tonearm has upgraded Cardas tonearm wires that connect to a Cardas CPIB Phono Block mounted on the upgrade platform.

LC-Audio RIAA Phono Amplifier with MC Light Powered Step-Up, my own DIY version. Very intriguing MC headamp circuit that is supplied by light generated by small light bulbs that in turn illuminate photo diodes producing pure DC supply voltage. So in fact the MC section is floating eliminating any supply and ground loop noises. The MM section is supplied using LC-Audio own Low noise dual regulator modules. I built it into a single enclosure with MC/MM selector, and Mute switch. All these function are selected by relays. The MM selection acts as a standby mode for the MC section turning the light bulb off to extend their life while keeping the rest of the preamp turn-on. It sounds very nice and very quiet. One of my best phono preamp. See www.lcaudio.com and www.diyaudio.com for details.
Graham Slee Era V Gold Clone (DIY) A reproduction of the excellent Graham Slee phono preamp, same parts, same PCB, different enclosure. Graham really knows his stuff, this one been on Stereophile Class-A list for four years.

some nice restoration pictures at http://amp8.com. It has 5-gang tuning capacitors, an 8-stage IF filter section, 4-pin ceramic type and an all discrete multiplex section. It has a beautiful sound, and that "in the next room"i, it really seems like you have musicians in your house. Amazing performance for a 30-year-old unit.
Yamaha CT-810 Nice little tuner that matches my new Yamaha CD-S1000. I bought it for that. Mods the Supply with new soft recovery rectifier diodes and MUSE Nichicon Audio caps. New audio output film caps instead of the electrolytic. Replaced a burned meter lamp. The frequency dial knob was very stiff, it should had been rotating freely and with speed with the big flywheel on the back. Disassembled the tuning knob and shaft. Was stick together because of old grease. Cleaned the shaft and apply silicone oil. Re-assembled and bingo! Now the dial is fast and smooth. Retuned the front end and fine tuned the dial accuracy. I compared it with my reference Sansui TU-9900 and the sound is very similar. Very nice and good little tuner indeed. See: fmtunerinfo

First Watt F5 Turbo V3 amplifier. I was able to buy a gorgeous Ayre V5 empty case on Audiogon and I'll use it to build my F5 amplifier. More details on this project soon. In the mean time see this great F5T project on www.fetaudio.com
Borbely Millennium 200 Monoblocks, Great amps from Borbely Audio that I had the chance to listen to at friends house. They use fully discrete FET front end, with Lateral MOSFET Final. I'll build a pair for me. This a private project.
Borbely All Fets Headphone Amp with companion All Fets Low Noise Discrete Regs, Fully discrete Class-A headphone amp and low noise supplies from Borbely Audio. I'll build one for me using extra parts from my Millennium project. I did my own PCB and I'll design a custom enclosure from FPE for it. This a private project.
Lovely Cube Headphone Amplifier. This is a clone of the excellent Lehmann Black Cube Linear (BCL) amplifier. I upgraded to SE status by replacing the supply main caps by Mundorf MLytic, the input coupling caps by Mundorf M-Cap MKP and Mogami audio cable, as the original SE. I also drive the opamp in ClassA. See this site for details www.head-fi.org for details.
Paradise Lost Phono preamp, version R3, Fully dual mono discrete phono preamp with shunt regulators and external dual mono supplies. I did my own PCB sets. Read the complete MPP thread or jump directly at www.diyaudio.com for details.
LC-Audio Low Noise dual regulator, my own DIY version. I'm planning in using them in my next Anagram Sonic-2 DAC and the LC-Audio own Phono preamp, see www.lcaudio.com for details.
LC-Audio RIAA Phono Amplifier with MC Light Powered Step-Up, my own DIY version. I'm planning in my new AirTight ATC-2 preamp to have an integrated phono section. I'll keep the power supply external for lower noise, see www.lcaudio.com and www.diyaudio.com for details.
RJM Audio Sapphire Headphone Amplifier. Two stages design with first a non-inverting op amp voltage gain stage then a second stage using a "diamond buffer" discrete current amplifier. See http://phonoclone.com for details.
Schroeder DIY tonearm clone. My Schroeder arm is almost completed. It missing only the wood wand tube. It has a micrometric VTA adjuster kind like the one on the Graham tonearm. Counterweight with fine adjuster brass screw, plastic (Rulon material) sleeve insert between arm tube and counterweight for smoother adjustment and vibration control. I'll use a kevlar thread for the pivot point. The mounting hole is the same as a REGA, lifter (JL-45) from Jelco. The lifter will need a custom slide section. The standard one is not long enough. See www.diyaudio.com for details.
PassLabs D1 Fully Balanced discrete FET Class-A output stage without any negative feedback for the ESS Sabre DAC (see below). See www.diyaudio.com for details. I'll use Twisted Pear Ballsie Balanced to single ended converter to provide both type of outputs. See this mirror site for the original PassLabs D1 DAC: www.passlabs.com
ESS Sabre New Reference 24 bits/192Khz DAC (8 channels combined to 2 channels for exceptional low noise floor) based on twistedpearaudio Buffalo DAC PCB with USB, BNC, AES/EBU and Toslink inputs, see www.diyaudio.com for my own contribution, an interconnect diagram that illustrates the different modules uses. I'll also use their upcoming Counterpoint I/V discrete fully symmetrical converter, single ended or fully balanced output, DC coupled, see it own thread on www.diyaudio.com. I built my own Supplies, a Digital Inputs, Simple Reg Modif and Transformers PCB. I'll mount it into a very nice enclosure from www.hifi-2000.com, Galaxie Serie. See www.diyaudio.com and www.twistedpearaudio.com for details
PassDIY Pearl 2 Phono Preamp. I did my own PCB, smaller than the standard PassLabs design. It fits on 6''x9'' double side PCB material sheet I used. I got very nice Mundorf M-Lytic power supply caps, Vishay RN-60D resistors all around, and 0.1% CMF-55 resistors at key locations, see www.passdiy.com and www.diyaudio.com for details.
Anagram Sonic2 DAC with TimeLock low Jitter Clock module built around Edel S2 development board from ABC PCB. See www.abc-pcb.com for details and full documentation. See also forum.stereophile.com for very nice pictures of this DAC. I just bought a sophisticated asynchronous I2S and S/PDIF FIFO and multiple SPDIF inputs/outputs kits to go with this dac. See www.diyaudio.com for details.
ZD-50 A sophisticated Gain Clone amplifier based on the LM3886, see www.diyaudio.com for details.
B1-DC Coupled Preamp with Shunt Regulator, The Mesmerize, see www.diyaudio.com for details.
Sonic Frontiers Line 1 Tube Preamp. I got the main PCB from an other diyaudio member at a good price. It a fully balanced design with sophisticated regulated power supply, almost completely DC coupled signal path(just one very good quality, low value capacitor) using a DC servo, high grade power transformer, very high quality 2oz copper PCB, three tubes per channel, input tube polarized with CCS current source, etc. For the price, I can never build such a sophisticated preamp, very nice indeed. To complete it, was only missing a delay timing circuit for the HV relays and a mute circuit that close when the already built-in DC error protection was detecting a DC offset at the output. This PCB was extensively moded with the best available, Vishay Bulk Metal foil, Caddock and Holco resistors. Multicap Thin-Foil fim capacitors, soft recovery diodes and instead of using the IC volume control, I use two external Noble potentiometers (much better, and no need for computer control). The original Line 1 has also an Headroom™ crossfeed headphone amplifier module. I built one too..., see www.diyaudio.com for details.
MOX Active crossover. Fully adjustable, HPF and LPF, 6,12,18 and 24 dB/Oct. It is based on the PassLabs XVR1 Electronic Crossover. It can accept op-amp or discrete op-amp module. I'm planning to use only the LPF section to power in dual amplification a bass module for my Verity Audio monitors. See www.diyaudio.com for details.
Yamamoto YDA-01 DAC Clone, with the Solid-State and Tube output sections. Very musical DAC based on the CS8416 MUX Digital Receiver and dual PCM1794A DAC chips. I made my own boards, and did my own change to the original design (better reset circuit, multiple selectable digital inputs, etc). The Tube section is using the WE408A. See the review of the YDA-01 (Solid State Output) and the YDA-01B (Tube Output).
The ShigaClone, a low cost CD Transport based on the JVC EZ31B Boombox CD mechanism. It is a 47Lab FlatFish Clone, see the original site at: www.sakurasystems.com for details and my own clone version at: www.diyaudio.com
PhonoClone3, MC dual mono phono preamp. Upgrade of the original PhonoClone using better shunt voltage regulators and optimized circuit and PCB layout. See www.diyaudio.com for details.
Peter Daniel PhonoClone version, MC dual mono phono preamp. Clone of the 47Lab Phono cube with shunt voltage regulators optimized circuit and PCB layout. Very specific parts selection, choose for the best sound, such as V-Cap, Muse & Black Gate caps, Caddock Resistors, MUR860 rectifier diodes, etc. See www.diyaudio.com for details.
"Heretical Tube Line Stage" Preamp with Unity Gain (explaining the "Heretical" name) to go with the F1 amplifier as well. Design optimized for Low distortion and very low noise floor. It is using the ECC88 tube, CineMag Input Transformer (for single-ended and balanced inputs), Dual HV active regulators using Film caps. Separate Power source with Transformers and Soft Recovery diodes. Finally an elegant Servo circuit eliminate the output coupling caps, and allow the use of a very high quality Teflon, small value input coupling cap. See www.diyaudio.com for details.
SDS Tube DAC using the PCM63-K DAC chip (maybe one of the best DAC chip ever made), passive I/V conversion and tube output. I'll add a USB digital input for the upcoming music server. See www.quadesl.com for details. An old design, but I have all the parts so...
Tube Buffer (In Progress...). Basic cathode follower with a choke for the cathode resistor. With ceramic comp resistors. The tubes are Jan 5687's and the rectifier is a 6v4. The PSU is a CLCLCR using only big Solen film caps and Hammond chokes. It has Edcor input transformers and Jensen in oil caps at the output. Finally there is an ALPS Black Beauty volume potentiometer. See www.diyaudio.com for details.

Toccata (Work in Progress...), A variation of the Arthur Loesch Tube phono preamp Design by Thorsen Loesch. Using a sophisticated power supply design with Fast recovery diodes, extensive CRC and CLC filters, HV capacitor multiplier, dual mono HV shunt regulators and individual tube heater current regulators. The preamp circuit itself is using a Cascode Circuit using paralleled input valves with selectable gain (56 to 72 dB), split RIAA equalization, tube lithium battery bias, extensive ground layout, point-to-point wiring, great parts like PRP, RN60D and Mills resistors, Solen, Obbligato and Sprague NOS Oil caps and Amperex ECC88 NOS tubes . I even included the preamp drive stage to be able to drive almost any interconnect with ease. The final touch, a real Acoustic Research Reference Phono front panel, with all the AR functionalities, delay turn-on, standby mode, Muting, etc. See: Toccata and Toccata MKII
