Bel Canto Design REF1000 MKII MONO BLOCKS (PAIR)

Selling a Pair of Bel Canto REF1000 MKII mono amps.  These beauties have served me well over the years but I am now changing to headphone only so I don't require them anymore.  Otherwise, I'd NEVER part with them.  They are astonishingly good.  I've had them since 2011 and so they do show a bit of wear.  There is one tiny nic on on of the faceplates as shown in pic.  I've been traveling almost non-stop for my work over the past five years so they haven't been used much, but prior to that I'd say about 20 hours per week.
