    All the capacitors of the power supply have been upgraded. The voltage regulation of the tape transport section has been upgraded During The intial overhaul. My tech was convinced That the best improvement would be obtained with his custom-made regulation card for the audio section.

    I have two sets of reproducing cards and three different stabilizer cards ie voltage regulation for the audio section. The first set of repro cards is based on the original architecture but with much higher-grade components: new capacitors, metal film resistors, most recent generation of transistors, special JFET, etc. Original card prior upgrade: After the upgrade: As the upgrades were performed Gradually, I can confirm there is a significant improvement Compared to the original cards: improved dynamics, reduced noise floor and much faster transients. In That respect, my technician Claims That the special military JFET is playing a key role: The second set of repro cards is heavily modified by MTSL. A picture with the MTSL card (top) and the card modified by my tech (bottom) The MTSL card is actually «Warmer» and less analytical. My tech upgraded the original stabilizer card During the initial overhaul so I can not confirm Whether there were audible improvements. Before overhaul: After overhaul: I got the MTSL stabilizer card and there were significant sonic improvements Compared to the modified Studer card: When looking at the MTSL card, my technician told me That he Could design something even better and I put him on the challenge. He developed a brand new design with impressive measurements: After many trials, I came to the conclusion That MTSL repro cards work best with the MTSL stabilizer card and the Same Applies to the set from my technician. I have an audiophile / warmer set (MTSL) and a more analytical / detailed set (my tech's). Do I have a preference? In absolute terms, I would say That I have a slight bias for my tech's cards though the MTSL sets is wonderful on harpsichord. Swapping cards is done in a breeze. There are still few upgrades in the pipeline: My technician is Currently working on a Improving the signal path in the vumeter bridge with the replacement of the switches by relays, new potentiometer, new circuit boards, etc. I have improved tape sensor from MTSL That my tech will install. It is supposed to Improve the Wow and Flutter. Finally, the balanced outputs will be modified by having the transformers being removed and Replaced by a Class A design.

    The TAD D600 is actually used as the DAC for the Aurender music server. The three boxes music server is basically an Aurender X100 on steroids: - The digital signal from the Aurender goes to the TAD through the Bel Canto USB interface Which Also acts as a reclocker. - The box beneath the Bel Canto USB interface is the custom-made linear power supply for the Aurender so I could bypass the switch mode power supply. There is actually a fourth Little Box That does not show on the picture: an Ethernet filter from Etalon Acoustics in Order to Enhance the signal when i stream. I have a subscription to Qobuz Which offers high resolution streaming (up to 192/24).

    The Allnic H3000V is a great phono stage. Though it is a full-tube stage, it is very quiet and noise free. It can drive very low output MC cartridges with ease (my transfiguration Proteus cartridge has an output of 0.2 mV). However it requires some tweaking in order to get the best out of it. Changing the stock rectifier tube is a must. Originally, I opted for a military Philips tube (5R4GYS) and the differences were Substantial. I then swapped For A KR Audio 5U4G Lampizator Anniversary version. The change is not subtle: more and tighter bass, better harmonics and a Wider soundstage. The KR Audio rectifier tube into the separate power supply: Originally, the tube stage was fitted with 4 Siemens E810F amplifier tubes. I also received from the distributor a set of Mullard tubes to replace the Siemens ones but They sound the same. I found the NOS Telefunken which are much better. In order to reduce microphonics, there is a silicone suspension for the amplifier tubes and it requires to use a specific tool to extract the tubes.

    The record label is actually Astrée. This was a side project to the main sister record label Valois. Jordi Savall has regained the rights on the recordings he made for Astrée and they are now available (in cd and downloads) from Alia Vox, his own label.

    I do not want to hijack Calle's report but I can give some explanation as, after all, this is has been my listening room for 23 years. The Fact That the loudspeakers are close to the sidewalls has no impact. There are Several factors coming into play: - The walls are not even surfaces. The handmade bricks are acting as largescale diffusors - There is barely any first reflection point on the right side wall. There are actually Several openings in the wall - The fist reflection point on the left sidewall is tamed by a SMT diffuser Which allows to place the loudspeaker close to the wall Loudspeakers placement was validated by comprehensive acoustic measurements (before and after placement of the SMT diffusors).

    Actually the analogue version and the one digitally remastered on a high resolution file are great. But I prefer the version by Ito Ema Which was recorded in analogue and digital. I have all versions : high resolution digital file, vinyl and tapes. And I will spare you the different versions that i have on harpsichord (on LP, CD and tapes).

    The 1981 version was actually recorded on both digital and analog. When CBS/Columbia issued the LP/vinyl in 1981, it was based on the digital recording. It is only several years ago that Sony decided to reissue the LP/vinyl based on the analog recording.

    There is the KL Audio ultrasonic cleaning machine. Mine has been working flawlessly since I bought it 4 years ago.
  11. One of the best interpretations of Mozart string quartets. I have Ciaramella and Christian Jacob on tapes (direct copies). It will be fun to compare both versions.

    No idea. I will ask my brick and mortar dealer who owns one as well.

    I have not changed the belt of my Brinkmann Balance Over the last 5 years since I acquired it.

    I have been playing with two sets of heavily modified repro cards. The top card was modified by Master Tape Sound Lab (MTSL) whilst the bottom card was modified by my local tech: Inserting the MTSL cards: I had to calibrate the MTSL cards with a MRL tape:
