Anybody using Wilsons or Soundlabs with Pass Labs?

I'm using Aleph 1.2's with a pair of Apogee Duetta Signatures. These replaced a pair of Krell KMA100 Mk 2's.

They are a very synergistic match. Bass is slightly less in quantity but much better in definition. The mids and highs are far superior and sweet.

Yes - I did. I tried a Pass Lab X600 with a pair of Sound Lab Auras (similar to Milenium series, but made of steel like Ultimate).

I also got to compare the X600 with Krell KSA 300S and Atma-Sphere MA1 mkII.2 OTL tube amps.

The results:
Atma-Sphere had the overall best performance, with the Krell a distant second. The Pass amp had NO BASS whatsoever to speak of. I suspect the Pass amps do not like the high impedances that occur in the mid-bass region.

DO NOT recommend you pair the Pass amps with Sound Lab speakers. However, I will say that the midrange and upper frequency performance was outstanding.

Wow! what a lot of interesting responses. I would have never guessed the Aleph models could give satisfactory service on the big speakers.

I have a pair of Wilson W/P 6 and tried a Pass 350 when I was looking for amps. The Pass was a very nice amp but just didn't do it for me. There was nothing wrong but I felt the magic wasn't there. I ended up with Atma-Spere MA1. The only thing I can suggest is giving them a listen.

Ferrari, Did you see Roma's post (Should I sell my Diva?) Could it be there is a dichotomy in perception when it comes to bass response? Shall we say, hi-fi bass, found only in audio, epitomized by truck bed mounted mega woofers, versus natural bass - like the baritone and kettle drum. I would want an amp that gets the texture and timbre of these big wave producers right rather than an amp that will substitute accuracy for cracking the plaster. My X-600 is of the former.
