Hi, I just bought the NAD replacing a 20yr old HK which took my old AudioTec speakers with it when it died. I hadn't used it much(a bit through headphones) until I received my M60s almost 2 weeks ago. I am very happy with the combination. Even with only 50 NAD watts/channel it powers the M60s easily. I usually listen at about 1/4 volume sitting about 8-10 feet away. It is extremely loud when approaching half way on the volume dial. Even running it through a 13yr old Sony CDP670 it sounds great...lotsa detail. The combo produces nice clean highs which I love good solid bass that can be felt through the floor upstairs and all the good stuff in-between. The price was nice too...not too many amps in the $500CAD range are built as well and my wife didn't gasp at the price. Best of luck.
