Need insight on these amps

Like all things audio, I would make sure that you can audition these amps before you buy. As a former owner of a Krell amp and you notice I said former, I was very underwhelmed with it. Power yes, music, nope. I also use to be a huge fan of ARC stuff but not since the early 2000s have I been anywhere near ARC gear as (to me) the musicality went away; no involvement or "drawing you into the music" anymore. If you are going to stay with solid state amps, then I would recommend that you get something from BAT. For me, BAT amps sound like music. I had a huge VK-500 that was marvelous and I was sorry to see it go but at 108 pounds it was just too large and I had no need for it anymore though it was nice to have around. It would drive anything.
Like everything audio, one man's meat is another man's poison. I am not a solid state guy  so I am limited as to what I can recommend in that arena other than the BAT amps I had and the former Krell and ARC things.  I cannot say enough that be sure you try before you buy!

That's an interesting response that I value a lot as i am a tubes guy myself.I'm not set on any amp yet but i'm doing my homework. As you know, it's not that easy to audition amps that are not current production amps on display. Btw, i owned a VK-200 way back in the early 2000 and I agree on their musicality. I will continue to read as much as I can before pulling the trigger. Thanks again. 

What amp did you have? What are you looking to improve upon?  What amp and overall sound characteristics of a system are most important to you?  Without this info we’re just throwing darts in the dark.
