The source knob is fidgity, but it in no way hinders the performance or audio qualities found on the 2150. As for the volume knob, using the remote control is not the most ideal way to go about adjusting the volume if you need an ever so slight adjustment, but I find it to be only a slight inconvenience rather than a total turn off, really.

It's good qualities far outweigh those two minor things IMO. I've heard that NAD in a Harvey Electronics store, and found that it was decent for the price, but tonally speaking, I think that the Outlaw sounds a bit more musical, especially in the mid range. I found the mids to be a tad flat on the NAD.

The NAD wasn't a slouch though, by any means, I just prefer the 2150's sound signature.
