Stan Warren Amplifier Mods


I am considering having Stan modify an Adcom 5200 amplifier. Has anyone had any experience on his amplifier mods. He seems to be very knowledgable about the Adcoms and would like to know from someone if these mods were worth it. Any help would be appreciated.

I am currently waiting for my Adcom 5500 to come back from Stan. If anyone want's to know how it sounds after the mods, please e-mail me and I will give you a follow up.
I have a Adcom 555MK11 with mods by Stan Warren that I bought here on audiogon, very nice amp. This amp compairs nicely with my Bryston 4bst, so whatever the mods are the final results are pleasing.
