Aesthetix Atlas Compared to Pass Labs XA30.8

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.....

I'll echo others' comments that the speaker will help drive the selection of the amp.  I formerly had Thiel 2.4s in my big rig system and found that the Pass X150.8 drove those speakers better than anything else around. I asked Kent whether it would be best to get the XA series monos or an X series and while I was prepared to spend the $ to buy the XA monos, Kent steered me to the X series for the Thiel.  The Pass products warmed up the Thiels beautifully.  However I've now moved on to Magnepan 20.7's and I prefer the Atlas on that speaker.  I'm also running the Aesthetix Janus.
