Any way to "improve" a Conrad Johnson MF 2500

Bad power supply caps cause a slight buzz with older amps thru the speakers. fYI

A "Shakti Stone" is the modern version of snake oil. The plug will cost a fraction of what you'll pay for the stone, and be far more likely to work.

When I had mine upgraded it cost $500 plus shipping there and back; well worth it.

Thanks for the responses. I am surprised that the Shatki Stone is considered snake oil, since the reviewer on Steroephile used it.....makes me wonder about the reviewer.

Chuck, I talked to the seller of the amp and he said he had both the MF 2500 and MF 2500A versions at one point, but sold the MF 2500A because it seemed to lose the musicality that he enjoyed in the non A version. He told me this after i already bought it, so there is not the concern his recommendation was colored by his wanting to sell the non A version. Can you tell me your experience when you upgraded? What speakers were you using at the time?

I'm seriously anti hum...I've been a serial "ground floater" for years (including pro audio live sound...although with electric bands the musicians may be mildly electrocuted) and even found a NOS "PS Audio Humbuster III" which really knocks out mechanical transformer hum.
