Should I buy a Class A Amp.

My amp sounds better with some types of music than others.

I base my findings on empirical evidence and what I hear, not on theory.

Nothing mythical about that.

Tim,

As they say, just because I don't know how to cook doesn't mean that I don't know how to eat.
If I hear the difference I hear it. Just because someone has ideas of what I should or should not hear doesn't change this.
Ralph's tone is often egocentric and condescending, and I believe he knows it. I do not question the quality of his amps, by the way, I never did. But I will leave him alone from now on.
So, yes, to state it again - I would not choose Kondo for jazz/rock and I would not choose Rowland, Pass or perhaps even Lamm hybrid for acoustic guitar music. I would choose tube amp. Which one? I don't know, I would listen to them all above certain level. But usually we have to choose just one, along with one pair of speakers, for many different types of music. My current amp is actually better for jazz/rock than acoustic guitar but not bad for anything. And speakers are the other way around !  However, it's a modest system by audiophile standards.
Let's just not simplify and distort things.

timlub - Thank you for taking the time to write your thoughtful post (7/26 8:07am).   Many members share your concerns about maintaining a sense of respect in these discussions.  This forum stands out for the quality and generosity of its members to share their knowledge and experiences.  It's a great thing!    Every once in awhile a poster has a bad day.  The trick is to have the good sense to catch a faux pas within the 30 minute grace period for edit or deletion.   Wouldn't it be nice if we could have that same 30 minute grace period in real life for editing or deleting what we just said to our significant other.  Ha!

Don, since you enjoy the sound of your present amp,the important factor, I suggest that you keep it. Invest in improving your "sound" with front end upgrades, interconnects. "Isolation for your digital" could be eye-opening and give the best improvement for $$. Equitech and Furman websites provide info. I have been amazed by the improvements from clean AC.
