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 user...it did wonders for my Krell KCT & FPB300c, Cary 306/200, AAD 7001 setup.
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.
