Which amps with B&W 800D's... Pass Labs or Classe?

I am finally down to the wire... I am considering either the Pass Labs X350.5, a pair of the X600's, or a pair of the Classe CA-M400's to power my B&W 800D's. I am having the hardest time making this decision. I love my music loud, and I listen to alot of large-scale symphonic music, choral music, jazz, and various recordings that are very grand in nature. I am planning on incorporating a center channel and surrounds eventually in a theater and multi-channel setup and I would like to use the same brand of amp for those speakers once I decide to add them. I have heard great things about all of the amps above, but I cannot make that final leap of faith. Are the Pass Labs amps and the CA-M400's from Classe in the same league? I would love to get the Omega Omicron monos, but the budget does not exist for those right now. If I get the Pass Labs X600's, I am considering upgrading to the X600.5's when the budget allows. I have heard great things about the class-a capability of the Pass Labs amps. I am not keen on bi-amping and I really need some help in making this decision. I look forward to your advice! Thanks.

I have CAM-400 on 800Ds with CDP-202 and CP-700. I am switching the CP-700 out for an Audio research reference 3 because it is a little too polite. But I cannot say enough about the CAM-400 and the 800D combo. The Bass is very accurate and powerful, and the treble is as refined as I have ever heard. They must be putting out around 800 watts (3-4ohms while playing?) because they will drive the 800D to near the limits in the bass range.

berjar, like you I am thinking about switching my CP-700 for a tube preamp. What other pres did you consider before deciding on the ARC?

I love B&W nautilus line and see the 800d's come up at a great price now and again, but I am so surprised nobody mentioned trying Krell here. I used to buy and sell all kinds of used amps and processors just to try,a nd the Krells always put out such incredible bass control, and lovely upper extension even on their 250 wpc home theater line amps, that I would be shocked if the new Krell class A amps that just came out couldn't drive those things all day with 300 WPC and to the point where you couldn't imagine needing more power. They are 90 db efficiency, and I tested so many brands.

The IBias Krell duo channel @ 300 wpc into 8ohms I am sure would rock those speakers all night long and sweet. I would love to hear that before trying others. I hate Classe, love pass but not as much as Krell, and McIntosh does work well with B&W, but I hadn't heard the beyond the 801 which was $120000 retail and had only the single huge woofer personally.

I recently purchased a pair of Classe CT-M600’s. I love these amps. They run cool and sound great with my Wilson Alexia’s. These are simply a higher power version of the CA-M400’s. Best amplification value in high end audio.
