PS Audio 6.2 preamp any good?

I have seen the newer and older PS Audio preamps, but know nothing about this one. Likewise, I hunted for reviews, and couldn't find anything either. It seems like it is selling used for around $200-250 these days, and I was wondering if it is a good preamp for the price? I have budgeted only $300 for a preamp, I am upgrading from an old reciever that sounded like crap with my new (to me) Von Schweikert VR-2's (speakers are very nice, though). I don't need a phono input, and the amp will probably be a used Rotel-991 (sounds like a good amp for the money). Thanks in advance!
