Near mint- putting a 9 since it is used- excellent condition Nad M22V2. 12 months old - I am the only owner. This is the amp I keep coming back to, but alas, got my hands on a PS Audio BHK mono block set for a steal of a deal. 
300 WPC using a Hypex Module. Expect clean and dynamic sound with very low distortion. ASR has reviewed other NAD M units and they measure extremely well and sound great to boot.
