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 :)
