Krell vs Levinson vs Pass vs Rowland

I have not heard krell and any tube pre. I have heard the krell fpb300 (and an all krell set-up) through my speakers and loved the sound, as well as I heard the 334 through my speakers and loved the sound also. The problem is I heard both set-ups a long long time ago and cannot really make a decision based on that.

I do feel the krell is a little harsh, thus a nice tubey preamp might make it a special combo? Or is this combo just a levinson??? See my dilemma?

I love the attack and dynamics of the krell and Levinsons, but have not heard the new Pass gear or the rowland with my speakers.

I guess if I had tons of dispensible cash laying around I could buy all 4 and decide at home, then just sell the ones I don't want. But who has this kind of cash??

I am guessing $28,000 and $18,000 is just a little more than I can afford. Or would want to spend on an amp, even if I could afford it!!

Thanks

I think I should clarify my system: The speakers I am running are power hungry Platinum Solos-these will not change. I have a temporary preamp (classe cp-35) which I intend on replacing with a tubed preamp such as a hovland hp-100, or sonic frontiers line 3. I also have a temporary cd player which I will replace probably with a levinson 39.

What I am doing is building my system from the speakers, then to the amp, then preamp and source. I want to make sure my amp will run well with tubed preamp, and I will tweak the system with cables etc to add warmth etc. I just want to make sure I have the best amp for those listed attributes. I feel I can always add warmth with tweaks. Thanks!!
