Pass Labs Amp X350.5 or X350.8 anyone compare?

Mtrot,
From The Pass Labs website.
In Class A the X350.8 35 watts.
In Class A the X350.5 40 watts.

Hifimaniac, odd that you would describe the Pass Labs Amp as bright. But I guess based on way we assemble our systems anything is possible.
I have the Eggleston Works Andra 2 speaker and with the Esotar tweeters they have never sounded bright.

To upgrade or not that is the question...

I have compared the XA60.5 to the new 60.8, I would assume the same changes in sound are across the board to varying degrees despite the different series.

First off, the amps are quite different looking (although typical Pass labs look), bigger, longer, heavier, totally different binding posts and back panel. Build quality seems a bit better. For sound, the background is much blacker, deeper and wider. The window into the sound is endless. Bass is far more authoritative especially at lower volumes. Textures, tones and body are all improved significantly. Quite frankly, they could have come up with an entire new nomenclature as far as I am concerned. The upgrade is not insignificant. As good as the 60.5s were, the 60.8s are just head and shoulders better in every aspect.

I would bet the X series amps offer the same overall improvements.

Interesting that the X350.8 loses 5 Class A watts, while the X250.8 gains 10 from 15 to 25 in Class A.

Jl35, I agree with you it does sound strange.But, I just talked to Pass Labs and Reno HiFI and both said it is minimal in actual usage and the newer technology uses it more efficiently.
Anyway, I ordered one (X350.8)to compare to my Pass Labs X350.5.
So, in the next few weeks I'll be able to post my comparison.

Pretty cool. Congrats on the new amp. I look forward to your comparison. That should be fun. I wish I was over there to hear both side by side. :D
