Anyone have the Pass Labs X260.8 amps? Opinions?

I would get a tubed preamp with Pass amps.

I agree. That's in my plan.

I am trying to figure out whether or not to go w/ Pass Labs separates or INT ?

Jafant,

It all depends on how much power you want and how simple you want the system. I am personally not a fan of the Pass preamps, but love the amps. I agree a good tube preamp with the Pass amps can be heaven.

FWIW, I used to own a CJ 17LS2 Premier preamp. I now have a Pass XP20 preamp. The XP 20 is the finest preamp I've ever owned. I did own a different Pass pre many moons ago too, and that one was just ok. Pass pre's have come a very long way

i pair the XP20 with an X250.8 and could not be any more pleased 

Yes, would like to know how good an ARC Ref 5SE preamp mated with a Pass 250.8 would sound. Speakers most likely Dali Epicon 8 or Proac Carbon Pro 8.

Selling your XA60.5's was a big mistake IMO, if you value midrange purity.
