Sure, service varies from case to case, even with high-class organizations, but I just wanted to pass this along. I own two EA iamp600 amplifiers as I use them with my "mini-monstro" rig powering a single Bergantino HT112 tilted back on a Carvin amp stand. Tremendous clarity, unbelievable range and, yes, great low-end, even on the B string. Hard to believe, I know, but quite true. Anyway, the oldest one (serial number "0000003") would drop to about half volume after it warmed up. Alarming, recent development. I contacted Gary at EA and he immediately stated he would fix it and I should ship it to him, which I did. Within a week, it was fixed and on its way back to me. Total cost, $35 plus shipping and he provided me with a full, technical description of what was done to the amp (i.e., replaced a voltage regulator chip for the preamp and modded the board to avoid another known potential problem). All this was done with a very friendly, professional attitude and no grief to me whatsoever. Of course, this is the way it should always be. But it's so seldom done, IME. Sure makes me look favorable on EA.
