first impressions of Pass XA30.8

My new Pass XA30.8 amp and XP10 came in today! After getting it hooked up to my Audio Physics Caldera II and my analog rig (Maplenoll Apollo with ZXY airy3/ZXY artisan phono, i cranked the amp up to get a quick listen. Mark (Reno HIFI) and Nelson Pass both said it will take about 24 hours for the Preamp/AMP to properly warm up and about 2 weeks for the Amp to break in. However, being the impatient person, i started spinning a couple of disks. I must say this is the best my system has ever sounded. I always thought i had a pretty decent system with my previous Khorns and my Marantz SR9300 reciever. However, when i moved, my Khorns just did fit so i picked up the Calderas and just wasnt pleased with the matchup with the marantz. I got a lot of input that these speakers needed a better front end and after a lot of agonizing on what to get, i got the Pass system. I was a little concerned that the 30.8 may not have enough power but as a Class A amp, it seems to have a lot of reserve power and with my smaller listening room is doing very well. The whole sound came together even better than my Khorns/Marantz combo. I am a little afraid because the advice is the sound will get better as the system warms up and the amp fully breaks in. Not sure how that can be because it is such a dramatic improvement already. the bass response is taunt and deep. Midrange so smooth and balanced. The delicate sounds like cymbals, bells etc just so much clearer. Crispness of each note (if that make sense) is like i have never heard. Again, my system was no slouch but i am beginning to understand why people on this site said (ditch the AV and give your system a chance). Many thanks to the knowledgable folks on this site who shared their thoughts and perspectives. Once i get my UNiverse set back up on my apollo and get some more time with the amp, i will give a freah update.
