Take a paire of REF 250s home and demo them in your system. Any dealer worth their salt will let you take a pair home for a week or so. You will find these amps to be absolutely wonderful. Also, if you are listening solely to vinyl, then you might want to demo a tube phono stage before getting rid of the pass amp. Take your time and demo equipment first before purchasing. The Audio Research REF Phono stage is the best I have heard and the REF 250 is really nice. But, I would bet that the Pass amp is also really nice, so first demo a tube phono stage and if you aren't happy, then demo the AR REF 250 amp.
