I am also a fan of NAD equipment. Very clean sound. I know some people like the musicality of tubes and vinyl, but my preference is to have the signal coming in undistorted (high quality digital, high quality solid state), and then have my speakers give me the sound preference I want.
My peak audio equipment stage was with a Denon DCD-1500 directly feeding into a NAD 2600A amplifier with adjustable gain inputs (no pre-amp) and driving Kef 104/2 Reference speakers. Each was well known at the time, and the sound was glorious.
