Best Pass Labs Amp with B&W 800 Diamonds?


Looking for some help on which Pass Labs Amps would pair best with the new B&W 800 Diamonds. I'm currently driving them with an X250.5 and it sounds really good, but from reading the internet is seems there's room for improvement. The combinations I'm considering are:

1) Buy another X250.5 and Bi-Amp. Read a couple of articles that says this is an excellent route and is definately the cheapest.
2) Go for power with some X600.5s (the .8s are still pricy).
3) Go with the XA series, like XA160.5 or maybe the XA200.5 if I can get a deal.

I really like the Pass Labs stuff, so I'd like to stay with them.

Any help is appreciated,

Kevin

Can you post what are main diff between XA160.5 and X250.5. I own X250.5 and found fail to power B&W801d.
I owned 5 different Pass labs poweramps, and in the past I owned the 800 S from B&W. I would go for the 600.5 in your situation. You need a paired set of mono's. The extra current will give you a better result than the XA series. I owned 3 different XA.5 models as well. The Purist Audio Limited Edition is one of the best powercables for Pass. I tested many on Pass Labs for over 6 years of time. I do consulting in sound7vision and I work in this world for over 17 years of time.
