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.

If you get the right cabling you do not need all this complicated and expensive active shielding. It is a big money maker for the manufacturer but, contrary to the maker's claims, it can be totally avoided with the right cables -- from a different company.

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

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?

Thanks,
