Love my Denon 2805 receiver. Was interested though in comparing the results of feeding it with analogue from my old but excellent Rotel RCD-965BX CD player, then switching to PCM input via co-ax. Both sounded terrific, but the analogue definitely had a little more detail (noticeable in subtle percussion things like low level cymbals). Checked with my wife in blind tests and she preferred the analogue signal every time. So an old but very highly thought of CD player (I bought it in 1993) has a better DAC than the Denon, at least as far as two channel music goes. So at what point on the expenditure scale would an AV receiver DAC be an improvement on the dedicated DAC in a decent audio CD player? Just curious!
