Aesthetix Atlas Compared to Pass Labs XA30.8

The Atlas has a solid state output stage that runs in AB I believe.
It would have more grunt than the Pass Labs although I am uncertain if you are playing at lower levels.
I have heard both and preferred the X series Pass Labs. I guess it depends on what speakers you are driving and what your sonic preferences are.

The midrange and high end on the xa30.8 are magical. The bass is great but if there has to be a week point of the amp it is the bass. It isn't about heart pounding room shaking bass the xa30.8 is about accurate sounding bass. As well if you dont know the xa30.8 goes into ab mode up to 110 watts or so into 8 ohms and something like 160 watts into 4 ohms. I can't speak towards the other amp as I have never heard it. 

You don't even mention the speakers that you're driving with the amp.  That will make a big difference to any responses here...

And the preamp?

Thanks for the responses....I'm driving PMC FACT8's.  I have currently unplugged my Aesthetix Calypso Preamp....My source right now is the Auralic Vega G2 with Auralic Leo GX Master Clock....It's running direct from my Vega G2 to the amp....Again, I'm not using my Calypso Preamp currently.   I was just curious how the Aesthetix Atlas amp would compare to the Pass Labs XA30.8 because it runs in full Class A compared to my AB hybrid tube/solid state Atlas.....
