Pass Labs X350.5 Vs. Mark Levinson ML No. 436?

For what its worth, I always thought the X350 sounded much better than ML's 336. (I used to own the X350 & X600s.)

The 350.5 has been improved, while IMO the ML has slipped. Further, the Pass has better extention (top and bottom) and is more true to your source. I always felt the ML 300/400 series were a bit rolled off in the highs. Cabling is going to play a big part.

The Pass - Theta synergy should be great and your Dynos are going to convey whatever goes into them exceptionally well. Good Luck.

I've listened to several amps vs both the #336 and #436 like the Krell FPB 350MCX, the Classe CAM 350, Krell KSA 250, and Bryston throught my Revel Salons. I found the that the #436 sounded much better than the newer Krells, (the dealer who loaned them to me confirmed this too) fuller bottom end, much more listenable, I thought the Classes sounded way underpowered and anemic, and the Bryston on the light side of the spectrum more like the Krells, (I have the least experience with this amp) The Krell KSA 250 running full class A has a tube like sound that the #436 couldn't match and a wide soundstage. The low end of the Krell was very dynamic but not as controlled and musical as the 436. The #336 is a good amp, and I owned it for over a year, but the #436 beat it in every aspect except looks, (I like the heatsinks.)
The guys at Audio Reveloultion list the 436 as one of the top products, and several of their reviewers have sold their previous amps to install 436s in their system.
The 436 has also been favorably reviewed in the Absoulute Sound, and Sterophile.
I have not heard the Pass amps at all, there are no dealers in my area, but I know they sound great by reputation.
Hope this helps.

ML 436!...for me.. generally the Pass Labs not have a good control of the low range..
