Pass X-250.8, X-250.5 or XA-30.8...or?


Hi.
I am looking for an amp to drive my Revel Ultima Salon 2's.

I have always loved Pass designs, owning a few of his great amps in the past.

I don't think the 30.8 will drive my Revels. And I'm hearing that there is a noticeable increase in sonic performance between the .5 and .8 amps.
I will be using a Krell EVO-202 as the pre.

Would love to hear your thoughts and observations.
I need a reliable amp as I live in Hawaii and shipping stuff to get it repaired gets really costly! 

Aloha!

Thanks.
He said that they were voiced slightly differently and that the 250 was more Jazz and the 350 more Rock. But mainly that the Revels would be very happy with the 250's output, even in my large space.
It's going to be good to get Mr.Pass back in my life :-)

My Studio 2’s are driven extremely well by a 250.8. I never feel I need more power, no matter how loud I listen (I can easily exceed 100dB). The pairing sounds superb.
