Anybody using Wilsons or Soundlabs with Pass Labs?


Hi ye all. I'm curious whether anyone has tried Pass Labs amps on formidable speakers like Soundlabs or Wilson Watt Puppies.

I tried the Aleph series on sound lab A3s and they were excellent within their power rating. Very natural, detailed, with good imaging. If one could find a pair of 1.2s one would be happy indeed.
Fdriver has an interesting perspective. One could order/update with the SL biamp option. One could then put Alephs or X series amps on the top end and perhaps Wolcotts on the bottom, or MAs if you wish. Or even 4 channels of Pass amps, if your electrical system is up to it. I believe the new crossover configuration offered as an update by SL would lessen the bass taste issues some of the correspondents cite. I feel recordings vary in bass impact much more than the excellent electronics all the correspondent refer to. Others, credible others, have used the Sunfire 300 watt on the bass and the Wolcotts on the top. HAve fun!
1. Fdriver I agree with your well-stated points. The aleph series if I recall correctly has a higher output impedance than the X which *may be* a better match for the SL in the low frequencies. However with the old crossovers I found the low power ones clipped with heavy brass, etc. That being said the Wolcott or the OTLs are the best amps, IMHO, for the SLs. I was going to biamp with Alephs but got Wolcotts instead.
2. Why doesn't Stereophile,etc. test the FR, etc.,of the amps under test with the speakers that the reviewer is using? This would show true system interaction. The dummy IHF load is only somewhat germane to the system context. The tests they do now are at best academic and irrelevant...ok, they do reveal the basic quality of the amp but if the amp shows 10% distortion it should be sent back to the manufacturer before it is reviewed. Sounds like Fdriver's own tests are more relevant and systematic, even though the results cannot be used to make universal statements, but why should they?
