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

@audphile1 

+1 I agree. I used an Audio Research Reference 5SE for many years with a Pass x350. Is a great combo… although, to me, a way better combo was with a REF 160… but that is another conversation.

@ghdprentice LOL I’m sure. I’m enjoying a Ref 6 now paired with my X260.8 monos, courtesy of my buddy who let me play with it for a week. Sweet combo!

@OP Late reply as I am no on USA time.

Just two final comments - once the specs don't show any red flags - listen!

Secondly, I wouldn't get hung up on technologies and suggest that you also listen to a comparably priced Passlabs preamp before making a final decision.

@soix I have 803D4’s (not D3’s) but you are correct about the upper registers. I’d like as much imaging, 3dimensionality and life like presentation as possible. I find magic in the small details and how notes can hang in the air.

@audphile1 I would consider a Ref6 SE but (maybe because of my lack of knowledge) thought it would be best to buy a pre amp which has Home Theater Bypass as 60% of the time the system is used for that.

You can turn the Backert off for HT , also it’s much more affordable than the VAC. Have not found a store that had both so I can so listen side by side. 

@garynospamm …Ref 6 SE does have a processor feature but the Ref must be powered on to utilize it. If you use your HT a lot, using Ref in that system would just result you in shortening tube life by running the unit unnecessarily.
