Pass X350.5 or Krell 302e?

I auditioned pass 250.5 at my local dealer and liked everything expect dynamics and bass. I am surprised by the comment that Krell 402E did not have bass that is not as good as than older generation of Pass??? Latest Krells are great amplifiers. I own latest Krell 302e and in my house compared it with Plinius sb301, Mark Levinson 532H, Gamut d200i and latest Hegel H4SE.
Krell has better bass, more airy highs and very energetic and natural midrange with very real 3d sounstage and of cause its dynamics are awesome.
I really would like to know if in this price range (around $10K) there is something better overall . I agree with some comments here that pre-amp can be an issue when auditioning pre-amp. It needs to be a great match with the amplifier or it will kill all the goodies that particular amp is famous for.

Krell FPB Mc series. I really liked the musical sound, but the stage was not the strongest part. Pass Labs gives a different focus on the sound of instruments. I am not talking about the stage. The Krell is more focussed on the overwhole sound. There are many Krell amp's I auditioned which were not that convincing or special. I sold my XA100.5 to a client with puppy7 sepakers. Was the best puppy audition I ever heared. I also auditoned more average demo's with Wilson Audio speakers. Often acoustic problems. Many had Krell amp's. The acoustic problems were not caused by the Krell amp's.

I own the Pass Labs X250.5 which drives my Wilson Duettes in the dining room and the Krell Evo 2250e which drives my Spendor STs in the bedroom. The VTL 7.5iii is the preamp for both. They are two very different sounding amps. In a room where the accoustics are not challenging I prefer the Pass to the Krell. The Pass has an wide soundstage, and excells in the mid-range, goes very deep in the bass and does not sound like a SS amp. The Krell is more analytical has better imaging and air around the notes and instruments and the bass is so well controlled that it sounds good in any room environment. I tried the x250.5 in my bedroom, which absorbs sounds and the whole soundstage flattened and lost transparency, the Krell was largely unaffected by the room. I am using the same interconnects and speaker cables with both amps. Both amps will benefit significantly from an upgraded power cable. I hope this helps.

I use a Purist Audio Limited 2013 powercable of 4000 dollar. It is a lot of money but I add's new qualities to all the parts were you Judge an amp for. I often do a-b comparissons between an map or source with a less expensive cable and a less expensive amp or source with a much more expensive powercabels. Most of the time people choose for the more expensive powercable and less expensive source/amp during blind audition.. Many people expect that the more expensive amp/source will be better.

I disagree about a Pass Labs amp sounding broken on a Wilson Sasha. My buddy has Sashas and when I hauled my XA160.5s to his house and hooked them into his system, IMO the Sashas never sounded better.

In fact, I've never heard a Pass amp sound "broken" in any system in which it was paired with appropriate speaker loads.

The ".5" version is a major improvement over the standard X or XA models.

I don't have any experience with Krell amps.
