Hi all, I've recently put together a system with an Arcam AVR300 receiver, and a borrowed Denon A-11 DVD player. I've noticed that CD playback with the Denon (via analogue) isn't a whole lot different from a line out on a decent personal CD player. Having auditioned a Cyrus CD6 and Denon DVD-3910 (with the AVR300), and spoken to numerous dealers and Arcam tech support, I've reached the following conclusion: There's a huge difference between DACs suited for movie use, and DACs suited for music (i.e. a good CD player will play CDs better than a high-end DVD player. Also, it's better to use the DAC on a good CD player than the DAC on a decent AV receiver - e.g. use an analogue, not digital, input). So: 1. Is this complete BS, or am I roughly on the right lines? 2. If this is right, then could someone explain (in very basic electronics terms) the differences between DAC technologies? 3. Would I benefit from a cheap (<300GBP) external DAC, to decode a digital 2 channel output (CDs) from the Denon DVD player to an analogue input to the Arcam receiver? 4. If the answer to 3 is yes, then could anyone recommend a product (or a DIY job)? Thanks for any info!
