i am looking to replace my Krell with tube amps,

thanks everyone for the input, it sound good Krell with tube pre and photo, it is that i have krell for over 10 years and thought is time to have a change.
i am waiting for my Aesthetix Callisto sgn. to arrive.
Thinking of powerful Tenor 175S, they said is the best power amp. i am looking for a used one, too much money for a new one.

I think audiovalve challanger 180's would be worth a look;el34,6550 or kt88 choices and power out ranges from 150 to 180 watts;I am using these on my soundlab m2's with very nice results.

VTL...nice...but for my money, the most musical...in this sense, not pejorative, but the ultimate compliment...Valve Amplification Amps (VAC by Kevin Hayes)...best voicing, for my taste...warm, rich, inviting...beautiful staging, low level resolution without that 'etched' quality that can tire or fatigue.
At least give them a spin...they are, in a word, Marvelous...

Good listening,

Larry

VTL 450 wpc and up. Wolcott is a good one too. Do you live in a warm climate? If so you may need A/C at least in the summer. I have a Callisto Partial Eclipse with two power supplies and it by itself heats up my room pretty quick. Although my room is smaller and is upstairs. I would like to try some high powered tube amps as well but don't have A/C at the moment.

I think you should wait till you get the Callisto to decide on amps. I also went from a Calypso to a Callisto and you are in for a treat. You may decide you do not need to switch amps.

I went from FPB 600s to ARC.
Depending on your budget, there is a wide variety to accommodate your needs and ARC tends to lean towards SS when it comes to bottom end control which is a real nice attribute.
I tried the VTL's as well and preferred the ARC based on the bigger model ARC I settled for. NO tubes will have that staggering control of what the Krells can provide but it was a compromise I was willing to take to fill the other avenues that the ARC provided. Good luck
