Best SS Amp - Pass Labs X350.8 vs. Luxman M900u vs. Ayre VX-R Twenty


I’m in the market for a used SS Stereo amplifier for about $8k-10k range, in the used market.

Source: Oppo BDP-105
Speakers: Tyler Acoustics Linbrook System II with 89db & 8 ohm.

The next step would be to add a Tube Preamp to connect my Nakamichi RX-505 tape deck.

Out of the following, which one do you recommend & why? I would prefer feedback from anyone who has compared any of these combination of Amps.
  • Pass Labs X350.8
  • Luxman M900u
  • Ayre VX-R Twenty
  • Jeff Rowland 625 s2
Later on the plan is to build a HT system & will add Amp for surround & center.

Thanks everyone for your replies. I searched for Coda, Hegel, Gryphon, etc. Most I could find was Integrated or nothing. 
The others, I never heard of them before. Which makes it more than likely that it’ll be a difficult to resell later on. 
I prefer someone to provide their comments based on sort of a/b comparison with any of the 4 Amps I listed above. 

I am doing music and home theater with Krell XD amps. I get the extreme dynamcis with movies and natural sounding highs and mids with music. I love these amps. I"ve owned most of the major brands and all amps have some sort of compromise especially if you want to use them both for music and movies. A  guy that only listens to classical music may not give you a good recommendation for a dual use amp and the converse is also true. You need to hear the XD stuff  yourself and see what you think.

You think AYRE is easy to resell?? As somebody who owned multiple Ayre amps I can tell you that you are sadly mistaken if this is your belief. Any AYRE dealer will tell you the same thing. If ease of resale is high on your priority list I would advise to stay clear of any Ayre Products. The KX-R Twenty Preamp is probably the only one that will move in an acceptable time frame...and even that wont be fast. The VX-R Twenty has been discontinued so that will be even tougher to move than the MX-R's.
