I disagree with the statement that an external dac won't do much to improve upon the sound of a lesser cd player. I have a Rotel RCD 971 and was auditioning integrated amps with it as a source. For fun the dealer connected it to an MSB Nelson dac III. Let me tell you , the difference was night and day. I also tried a Rega pLanet 2000 without a dac (which is supposedly quite a good player), but there was simply no comparison. The dealer also had a cheap universal player from Pioneer which was connected to the nelson dac... this setup also blew away the Planet 2000 in every way...depth, dynamics, soundstaging, blackness, detail retreival...
I took the Nelson home. Simple as that.
