I'm in the market for a decent reel to reel mixdown deck, and i'm leaning heavily towards a Revox. my question is, for anyone here who has worked with either one, am i going to notice a big difference in features or performance between the B77 and the PR99? the only differences i've noticed is the PR99 has a digital tape counter and XLR in/outs, and the B77 has RCA, which is really what i'm concerned about - are the XLR connections going to give me a noticably nicer signal in and out of the deck? the cable runs to and from the mixer won't be long (under 10 feet), so i don't think i need to worry about noise from that, but just in general...? thanks.
