Pass Labs AMP’s- What is the best Pass Amp Sound for You from past 10 years


So I have an XA-25 and its outstanding. I’ve tested the XA60.8 mono’s and there was not enough difference to move to them; no jaw dropping moments. Don’t get me wrong they were fantastic, but so is the XA25. Looking at the 350.8 or 250.8, etc.... even in comparison the Integrated INT-250... If you love it; want to explain what you like and why? I’m wondering what others are thinking... 
My set up: Wilson Sophia II’s, XA-25, Pass Labs XP-22 pre, Merging+NADAC.

Lesonaussie2- Then I have a question. Of the big Pass amps, is there one that shares those characteristics of the XA25?

My Sophia II's are single wired, and per your article and in general - 
     [the speaker is single wired, not bi-wireable. So, simply use one channel of each amp for each speaker.Take the single interconnect Left or Right out from the preamp and direct it to only one input of the amp. One channel goes unused. The output from the single channel is sent by the one speaker cable to the single pair of binding posts of the respective speaker, and only one channel per speaker, providing better performance than one stereo amp]
Did Nelson ever comment on this? Do you get the full power to the one channel being used? Does this change anything with respect to Ohlm's and speaker? I am curious and have wondered about this. Is there a better way? 
Big fan of the J2. I switched from tubes to the J2 about 4 years ago and have never looked back. I couldn't imagine two, the heat from one warms the room. Currently driving the M3 Triode Masters and am quite satisfied. If your in the market for an amp and have reasonably efficient speakers First Watt is worth a look.
Another happy 250.8 owner with the XP 10 pre handles Maggie's 3.7i extremely well.
Hi all,

I am considering purchasing the Verity Otello’s and specs are as follows:
100 watts of music power, 93db @ 1w and 1m, Impedance: 8 nominal and 3.8 minimum. Based on these specs I am looking to match a Pass Lab or First Watt
amp. I like the warmness, tubelike sound of the Pass Lab. So far considering the INT 250 or maybe separates like the X250.8, but want to match the best amp to the speakers mentioned. I listen to a lot of vocals and music with heavy brass, so looking for something warm but not lacking in detail. All suggestions are welcome, please include reason for your preferrence.
