if i were you i would talk to Klaus about how to best upgrade the mono extremes. he has built reference versions in the past on request. have you ever heard of the full Gary version? thanks....WCW III
What is the "full Gary version?"
Being unafraid of just about any tweak, I collected some info on the "full Gary" version, and was considering to mod my extreme monos gradually towards that version of the amps, but when I saw that the parts alone would be $2000+ to get there, I decided that given the zero resale value added, I'd better leave the amps alone. I did add some damping to the chassis and swapped power cords, placed them on decent supports, but nothing else.
Depending on the outcome of a comparison tests with some Class D amps in the near future, I may decide to move into that direction, or stick with the Odyssey monos and do the "Full Gary" mod myself. The good thing about being able to do your own modding is that you can take these things in stages. I'd probably spend $500 on an small first upgrade, replacing input capacitors, swapping all Wima bypasses with Auricaps, replace connectors and wiring, etc. But it'll take some serious thinking before I get started - I'm somewhat reluctant to hack up the most expensive components in my system.
The fact that I haven't done anything to the amps is quite a testament to the quality of the product. Even my speakers, which seem to be able to keep up with any upgrade I throw at them, have been modified to some extent. Everything else in my system has undergone multiple overhauls during the period I have owned the extreme monos. They simply work very well the way they are and not having the cash to simply toy with $2500 amps, I am waiting as long as I can to make up my mind about the modding.
check out my web page and you will see that I am usually not that worried about seriously modifying gear, or simply building it from scratch like my DACs.
I"m told the full Gary will make the Monos super-revealing - possibly too much for some lesser systems. So even if you could afford those amps, you may be starting to replace everything else to get things back into balance.
