AliG - It is possible that there may be nothing I dislike about my AVA amp. I cannot actually say that there is anything I dislike about it. It is highly possible that changing out the amp would not result in achieving my goal.
I am trying to achieve a slightly different sound from my system. A slightly more laid back or relaxed sound, but not much – just a wee bit. I really enjoy the clean, clear presentation I’m getting for vocals, acoustic, jazz, piano, chamber, opera, classical, bluegrass, etc., but for me it’s a little too clean/clear for rock and blues, much of which is not well recorded. Though I don’t want to lose much, if any, detail in the process. I love the way my system can growl. I just wish to add a pinch of purr as well.
For various reasons I would prefer to NOT change out my speakers, preamp, and CDP, at least not at this time. That leaves me with very little to change: amp, speaker wire, ICs, and power cables. And of those, the only piece worth any dough to fund a change is the amp.
So, there ya go. I just thought I'd play a bit with different amplification. But I'll only sell the AVA if I can replace it for near its value and still meet my sonic objective. It would not surprise me if that turns out to be impossible as the AVA amp is a gem, especially for its price.
