I own an Edge CDP and find it to be a great match with my Conrad Johnson Act 2 pre amp and Edge NL12.1 amp. It required a long time to break in but once it did, everything sounds great. Its greatest strength is imaging and spatial separation. It is very nuetral and does not favor or romanticize like other CDPs. I compare it to my Electrocompaniet CDP and the Edge has much better PRAT while the Electrocompaniet has the "edge" in soundstage and bloom. Pairing is key and I think one must be certain to understand that it is dead neutral. Match it with a good set of speakers that can image and youre on to something. Note- it does not use balanced interconnects.
