Wanting to try a tube amp.

He is correct. Different topologies will give you a different sound. You should really listen to some different tube amps before making a decision.

ARC sounds somewhat cold to my ears, whereas CJ sounds warmer. Mcintosh will sound different still. It all comes down to what you expect a tube amp to sound like and picking one that meets those expectations.

Maybe save up and go to the RMAF or one of the other audio shows. That way you can audition plenty of amps in one place and make an informed decision as to what sounds best to you.

Todd,
I feel like I am in your boat too when it comes to hearing and lower level play.
Couple thoughts. Vlad's monos or Decware Monos. Both fairly reasonable
and should have good synergy with your system. Make sure you get a trial
period. I have an AM dac too and love it!

@cincyhound - Vladimir Bazelkov makes the 6c33c based 45w SET monoblocks. He is the Audio Mirror company. Sorry for not being clear😀.

Lot's of great suggestions and recommendations. Really appreciate the information. Since I live in Colorado, I might wait for RMAF. I hate to wait. I am kinda leaning towards the Prima Luna 400. Like the analogy on the cars I'm a sedan. But I want to tinker with my ride. Lots of options for tubes to get a different sound. Thanks again everyone.

If you're already deaf, ARC is good, but maybe a little overkill.  Be aware that the care and feeding of a properly maintained ARC tube amp can equal the cost of a used ARC tube amp.
