Pls help me decide Pass Labs X250.8 or Luxman M900u

I want to upgrade my 2 channel audio. I have a 7.2.4 Home Theater system I am in the process of upgrading. Recently I upgraded my old B&W N805 / HTM2 to the 803D4 / HT81D4 and relegated my N805’s to Surround duty (and they excel in this roll!)

I have been driving (due to age of system) with a Pass Labs X5, which I will keep for surrounds and center on HT , but I want to upgrade my 2 Channel Audio. I currently am trying to decide between the PassLabs X250.8 and the Luxman M900u. As these B&W’s can dip down below 2ohms I want to make sure I buy an amp which will bring out the best in my system and handle these dips. I will also be buying a Tube Preamp with HT Bypass -(looking for a used VAC Signature Mk5 SE or the new Backert Rhumba Extreme 1.4)

Anyone with experience with either of these amps and B&W 800’s would be great to hear from.

Thx!

My recommendation would be to find a retailer that sells those brands and get a demo. I don't think you will like that combo. Google Ohm's law and you will see that Luxman meets the criteria of how low they go; however, with the combo of B&W I think you will be disappointed and feel like you are missing something.

I use that on my YG’s and Vivid Giya G2. It has the tube preamp built in! So you will save 10-20k in cables and preamp! I will put this integrated up against 50 grand of separates!

Pass Amos do not do well with difficult to drive speakers. The Luxman is definitely the better choice, at least based one driving Wilson Audio speakers. I can’t abide the B&Ws lack of coherence- the brutal tweeters. All the remaining talent left that company and founded Vivid.
