Revox A720 and Revox A50
I have nice sounding Revox setup. I want to add a Revox A720 receiver + pre amp to a Revox A50 integrated amp because the A720 should give me more flexibility. My other components are Revox B710 cassette player, Revox B225 CD player and AR turntable. Any thoughts on pre amp + integrated amp combo?- Drummond
