NAD M23 Stereo Power Amplifier

NAD Masters M23 Stereo Power Amplifier
We have a client that recently purchased this unit and he has made some changes to his system going shortly after buying this he is going from 2 channel to a 5.1 system and has no use for this in the new system design.

This unit is in MINT condition.

No warranty is offered or inferred.

Please no low balllers.
