In the early 90's, I used three NAD 7120 receivers for about 10 years. They sounded great with my vintage speakers and worked perfectly.
In 2018, I purchased a NAD Master Series M12 preamp/DAC and M22v2 power amp. The build quality was excellent, they worked great, and the sound was crystal clear with a nice tight bass.
IMHO, NAD makes excellent hardware.
