Modding Synergistic Research MPC to Galileo status

I recently had the good fortune of upgrading my stock Synergistic Research MPCs closer to Galileo Status by the help of a friend who is inclined to do such work.

He replaces the Synergistic MPC's four cheap, general purpose 1 amp rectifier diodes with four ultra fast, soft recovery IXYS rectifier diodes and the 470uf 50 volt dirt cheap chinese electrolytic cap with a 680uf Panasonic FM extremely low impedance, high ripple current, long life (7000 hrs). It is now a super low noise power supply.

This mod provides better shielding to Synergistic Research cables resulting in more transparency, blacker backgrounds, increased detail and warmth with even lower noise floor than stock MPCs.

I was really taken aback by the improvements mentioned above. When considering the cost of a Galileo MPC, this mod is a downright bargain.

The cost of this mod will be $40-50. I can provide contact information for additional questions regarding components and price.
I've heard a lot of word about the Bybee Quantum Signal enhancers and if you install 10 + within your system($1000ish) it would take it to greater levels. I'm awaiting for some to be available. Even your tv will benefit from them.........
I too would like to add my very delighted feedback of Michael Spallone's SR MPC mod magic. Long time Agoner and enthusiast and can say that by far this mod has been my best and most cost effective tweak in my system over my 30yrs in this hobby. Based on the feedback from this forum, I sent Michael all (4) of my MPCs (for my SR ICs, PCs and speaker cables). Michael readily communicates and was a joy to deal with, very consultative & knowledgeable and turnaround was fast. I have had the modded MPCs in my system for a little over a month and I am more impressed every time I sit down for a listening session. The biggest impact is in a much blacker background which seems to allow the delicate details to emerge producing more air, separation, a deeper wider sound stage, more dynamics and overall a more 3d sound. My speakers disappeared. I am happy to recommend Michael's mods to any SR did wonders for my Krell KCT & FPB300c, Cary 306/200, AAD 7001 setup.
Thanks Colin for all the kind words. You should know that Colin is the first that has experienced my latest SR MPC Ver. 2 mod. I have changed the rectifier high speed diodes and the electrolytic cap, and as needed, bypassed it with a .1 or .01uf  polypropylene cap. I am now able to do away with the circuit board, and hard wire the components because of the now much smaller size of them.
 The sound is so much more transparent, with unbelievable air and decay, and with a wide open sound stage that now just explodes with unreal width and depth. It is so much better than my original SR MPC mod which was designed to be a great improvement over stock SR MPCs while sometimes approaching the performance of an SR Galileo MPC in some systems, that it is laughable! But such is progress.
 My new Ver. 2 mod is in another league altogether, now not only bettering the performance of my original MPC mod but now far exceeds those of a SR Galileo MPC as well.
Just chiming in on this thread and am happy to add my experience. Based on a comment in my system description I sent Michael two of my old dual lead MPCs to mid to Ver.2. They are on my two PowerCells and surplus as I'd already changed them out to Galileo MPCs.

Having gotten them back (super fast by the way!) I am very pleased to say that they represent a nice upgrade even on the Galileo. My system is finely tuned so changes such as the addition or removal of one HFT are pretty apparent. In this context the MPC Ver.2 go a good step towards making the system even more natural and open --  

sounds are more natural and integrated and it is easier to her each instrument in its own acoustic (case in point “All I Want” track 2 on Tierney Sutton “After Blue”, untangling the bass from the vocal is what this track is all about, ideally the bass should be well separated in space from Tierney's vocal, and the vocal itself should have uniform echo into each corner of the room (a really hard trick to pull off if your room treatment is not ideal)) -- the MPC upgrades made a good improvement in this regard

I'll now be sending six more Galileo MPCs to Michael for his work and will report on the cumulative effect

Further to my last post Micheal suggested I try the modded MPCs on my speaker cables rather than the PowerCells -- great suggestion as this placement (with Galileo MPCs back on the two cells) made a nice step up. It also freed a Galileo MPC to go on the Element CTS power cord that powers the quantum strip into which all my other SR power cord MPCs are connected -- another step up

Through all of these changes the effect I hear with each improvement is a lowering of the noise floor which seems at first to sound like a drop in perceived volume -- in fact I think what we often perceive as loudness in audio reproduction is actually the cumulative noise in the system, as the noise is reduced we can open up the volume control and appreciate more of the dynamic range in the recording. A great example of this is using a track from Vienna Teng's live recording "The Moment Always Vanishing". This is the last track on the extended version - "Soon Love Soon" (unfortunately only available as a memory stick live at her concerts in 2010 but there are a bunch of versions on YouTube from other shows so you can get a sense of what I mean). This is a recording of all the concertgoers singing along to a quiet slow song. As you get the noise floor under control it becomes easy to pick out tens of individual singers and hear each part and where in the room they are sitting. This even holds with applause, each clap and each person clapping is an individual -- and to think this is off a 16:44 DAT field recording -- makes me wonder what all the fuss with hi-res is for (ps I tend to do listening for system changes using my DCS stack as it's easier to do A:B comparisons, I also have an OK LP system which is my ultimate preference)

Anyway as I appreciate more of the value of noise control my next step will be to invest in an SR Transporter to power all of my source leads -- I'll report back on that when I get it installed
