I have been there and done that as well. Used to own the Krell KSA 150, SUMO Andromeda, Classe� Monoblock, ARC D-90, Counterpoint and Quick Silver monoblock. They all sounded different to my ears with each one of them has its advantages and disadvantages. The ARC D-90 was very lush sounding except in the extreme high frequency when it gets a little harder, the Krell presented a different kind of sound with full authority in the bass region coupled with good midrange. The SUMO was lean sounding and has a similar disposition as the Counterpoint, however the Classe� was a little dark compare to Quick silver which is excellent in the midrange and midbass which doesn�t have much to offer below it.
The amp that had me stumped for the last 5 years since I owned it is the ARC D-250 tube amp that put out 250w/c. I am not saying that this amp is one of the best out there it is far from it but in IMEE with other amps that came and went in my system it is far the best that I have heard. It is the only amp that drove my ML Monolith III to its hilt with ease as the case with the Thiel that I am using presently as well. BTW, this amp uses a lot of electricity and it can generate enough heat to heat the whole house as it has 32 tubes. I may trade this amp someday but for the time being, it is more than I need to drive my three speaker systems that I have lying around in my listening room with aplomb with no harshness, edginess and fatigue after effect to my ears.

I don't have enough experience to know for sure but it seems to me the best possible sound would come from a MONSTER tube amp.... Unfortunately, I don't have the space or the cash. ;-) As for keeping my room nice and warm this 'little' Krell runs quite hot during normal operation drawing anywhere from 625-watts to 850-watts continuous. It drops down to 75-watts in 'standby' mode. I commented on this in detail an earlier post.

  The Krell KSA 150 power amp that I used to have sucked about 1,200 watts of power from my wall electrical outlet during its peak demands.
  However, the ARC D-250 sucked out even more at about 2,000 watts during its peak demands. I turn it on, leave it on standby for about � hour before listening, and turn it off right away after the listening session to conserved energy and my electrical bills.

From 50Hz and up, it's the best amp I have ever heard.
That's not an amp, that's a freakin whole house space heater!!! 8=) nt - Dad 09:13:49 10/04/04 (2)

  it's time to replace the screens with storm windows, clean the fireplace flue and switch the SS amps for tubes.

  My listening room is in the basement so having this amp turned on and generating heat saves me a lot of money on my heating bills. As I can close the heat, register in my listening room to redirect the heat to other rooms in the house that needs it the most during my winter listening session.
