For sale, a Denon PMA-655R in working order.  This is the champagne finish version, which seems rarer than the boring (my opinion!) black version, not to mention more attractive.  It sounds great to me, and if I didn't already have several amps would've been more than happy to hold onto it.  I made a video of it going, though this is just to prove it's working and obviously not a meaningful way of judging the sound quality.  But the amp is for local collection only from Hereford (too heavy to ship, sorry!) anyway so you're more than welcome to listen to it beforehand.
