Have you tried Pass Labs XA's before?

Sm2727:
I am married but not rich... Actually, I still didn't get the chance to try XA's. But anyway, I have upgraded my Aleph 2 to X-600 for I need a lot power to drive my speakers. Hope I can get the chance to try XA later...

You have aleph 2's and are considering an XA? Did you marry rich...get an new job? If so please adopt me so I can listen to the XA's.
