Amp for PSB Stratus Gold speakers

Looking to replace my amp. Currently using a Dussun V6i 150 watt integrated amp. Looking at a Pass x250 with 250 watts. Anyone using this combination that can give me an idea of what to expect. Audition is unavailable.
Well, just bought a Musical Fidelity Nuvista M3 integrated. with 275 watts, that should have enough power.
Sounds like a nice pairing. Enjoy!
