NAD makes really good entry level gear (to high end audio). Not a bunch of extra functions you don’t need, but solidly built, and constructed for good sound quality. I gave a friend of mine one I had over 35 years and it sounded much better than what he had.
My only comment is that putting all those functions in one box introduces many compromises. Today a good quality system will be made of separate Streamer, DAC, Preamp, and amp. However many folks are now using integrated amps, which are a preamp integrated with an amp, so only three components. If you think you may be interested in pursuing a good system I would consider at least separate Streamer, DAC and integrated amp. NAD and Rotel have a number of good ones. The more you spend the better they will sound. This will greatly facilitate upgrading as well… you can do one piece at a time.
