I've noticed that the M6i has been discointuned with the arrival of the M6si which has resulted in dealers offering it for around £1500 as clearance. This seems stonkingly good value to me but I'm also conscious that its a relatively older amp now and maybe technology has moved on since its launched, particularly in respects of the built in DAC. Whats peoples views on a M6 for £1500? Would it be better served getting a Roksan M2 or similar?
