Pass vs Simaudio

I am looking to upgrade my amp. My current system is Accustic Arts front end, TACT preamp, Simaudio W-5 amp and Von Schweikert vr5 speakers. I am thinking about the Simaudio Evolution series W-7 or the Pass x-250.5. Any thoughts on these 2 as an upgrade ?? Any thoughts on other amps in this price class. Thanks.

If you haven't heard the new Ayre gear, your comments are irrelevant.

Thanks guys. I have looked on multiple boards and can't find one person who didn't have really good things to say about the dna-500 and every comparison put it above the Pass and Simaudio. I think I will go with that. The other alternative would be to biamp with a tube amp for the top.

If your choice was DNA-500 i know you will be very happy and satisfied , had mine about 2+years with no looking back or a thought of a upgrade, that's always creeping in my mind!

I've had my Pass X250.5 for almost 2 years now. I'm extremely happy with it. I've always used Audio Research tube preamps with my solid state amps though.
Prior to the Pass, I had McCormack DNA-225 stock, then had it modded to almost platinum(everything done minus XLRs).
Pass is better. It is more effortless, dynamic and more true to life sounding. It seems like it has no limits even with my not so easy to drive B&Ws. I haven't heard Simaudio Moon next to Pass so can not offer any thoughts on how they compare. One thing I know, I have no desire to try any other amplifier. And that's for almost 2 years now which in this hobby is almost like eternity :)
