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 am not a technician then a stupid question: why do not replace the MPC by a 30v DC laboratory supply ?
Hello Michael,
I recently purchased Universal Speaker Cells and have two standard SR MPC's which I'd like to have modded if you are stil doing this work. I am familiar with the Galileo MPCs as I have a dual on on my Powercell MKII. Please provide contact information. Thanks in advance - twochanneldave

I got much better results with Bybee accessories than with the SR speaker cells. You might want to look into their products. I am not connected in any way with them, by the way, except as a happy customer.
Hello Sabai,
Wow - Not sure what you mean by Bybee accessories? I'm thinking about including Bybee Rails on a ModWright Oppo 105D.

Anyway, I use SR for power distribution as well as the Galileo Speaker Cells and couldn't be more pleased!!!

Can you be more specific in your comparisons?

followup -
A month or so ago I found this thread and was intrigued. I've thought about upgrading my SR Universal Speaker Cells' two std MPCs to Galileo MPCs since I bought them. But, I would need two and that mean't about $800. I thought - no way... but, I remembered what an impression the Galileo MPC (2x) made to my PowerCell 10SE MKII. ...hmmm, what to do...

Based on this thread, I eventually got in contact with Michael, sent both of the units reg mail on a Monday and had them back (even burned in overnight Thursday) on Saturday. I really couldn't believe how fast Michael turned these around. More importantly, I couldn't believe what a difference they made!

Right off the bat I heard increased high end extension, wider holographic spacial representation; yet, with more precise instrument localization - especially strings. Low bass pitch was even more melodic. The background wasn't blacker - just full of more of what the venue must have really sounded like. I like that... I like that a lot!

The modded MPCs are plugged into separate SR Tesla Plex(s) because of the layout of my room. I use Nordost Norse Bi-Wire Jumpers configured diagonally; (or +ve) - red and (or -ve)- black on my Legacy Whispers.

Michael's mods are highly recommended!
