Anybody happy with high power Krell?

I have had Wilsons with Mark Levison gear run me from the room, I'm not sure the Krells were necessarily the problem there. I have owned several Krell amps over the years. My current one is a KSA 250. Before that I had a pair of the KMA 100 mkII, and before them a KSA 50 mkII. So you may guess where I'm headed. I like the Krell amps, but not all of them. The KSA 50 and the KSA 250 are considered to be two of the best amps they ever made. I like the pure class A power and detail, and their bass cannot be beat. I have not liked the S series amps as much as the KSA series. I'm now auditoning a FPB300. The FPB is much more open and detailed than my KSA 250, but also, so far, seems lighter weight. The bass is tighter than the KSA but not as dramatic.
Like any other component, it will depend on other equipment, the room, and your tastes. There is no perfect anything out there.

Class-A may not be the right thing for you if the amps are on all the time, they will generate a lot of heat (they are not proper Class-A if they don't).

But there must be something wrong if a 350W Jeff Rowland amp isn't enough. I would try other options, remember that the Krell only gives you a 3db upgrade.

I have a Krell KSA-250 (1993 vintage). I could not be happier.
I believe it compares very well to the best out there. Of course you need dedicated AC Lines atleast 20-30 amp line. It draws 12 Amps at idle.
And I am using the Whale Power Cords and PS Hi current power port.
It also can warm a room up considerably.

Man Osiris those things are huge, if you can swing them(the osiris) go for the big boulder mono's. I have the snot that came out of the nose of the osiris(eclipse, avalon) and enjoy them very much with tube power but you would need some HUGE tube amps to handle that set up. What do you use for surrounds? Eidolons?

lol. but seriously...if anyone here IS using eidelons for surrounds, i will personally drive to your house and kick your a$$ for free. email me.
