the adcom and nak are 80s era pieces--digital technology has advanced quite a bit since then. i believe that more current players like the rotel will have better frequency response, more detail, etc. i've owned the adcom--as a standalone unit it was only fair, but it worked well as a transport w/ an external (musical fidelity) dac--because of the varible out i connected directly to the power amp, with good results. that said, before buying a new cdp, i'd get a dac (such as the aforementioned musical fidelity or cambridge dacmagic) and try it with the adcom (i don't recall if your nak has a digital out).
