Thanks Tom.

There also may be more inputs on some versions of the DAC2. Study Benchmark's website for facts and details. They're nice folks, too, so don't be bashful about calling them up and asking questions.

The other thing about a high-quality external DAC like a Benchmark is that they build a super analog stage after conversion. Many CD players go the most cost-effective route, using either a minimal-parts design and/or cheap parts. Denon has a reputation being better than average, so you may already be working with a great design. Do you not like the sound of your player? I think you live in NYC, which means you can actually take your player to a hifi store (they still have them in the city, I envy you!) and try out external DACs as well as newer-vintage stand-alone players. Given the vagueries of room acoustics and speakers, I recommend you bring a pair of headphones you trust. One mark of a good DAC and for that matter a good stand-alone disc player these days is that it has a high-quality headphone amp.

>>> Keep in mind that no 2-channel stand-alone DACs that I know of can decode a digital signal from a DVD movie disc. Some can decode DVD-Audio discs, as long as the player is sending real-deal 2-channel PCM data. Some disc players have built-in facilities to trans-code movie-sound formats to PCM-over-SPDIF that DACs universally understand. Bottom line, in most case, movie-sound will need to come out of the player's analog outs and the SPDIF coax or optical cable will be for CD audio and perhaps 2-channel DVD-audio. I have not seen an external DAC that decodes SACD discs, even those that decode DSD files. But just because I haven't seen such things doesn't mean they don't exist!
