Hey!
Just a question here. I have a Yamaha RX-V2200 receiver and a Yamaha CDC-685 5 disc carousel. I performed a little experiment by hooking up the player to the receiver with an optical cable AND a set of kimber cable interconnects. Basically, I wanted to A/B test the difference between the digital and analogue connections. To my surprise the digital connection sounded fuller and more musical, and had a cleaner and more vibrant top end. The difference was rather subtle but noticable. I should also mention that I performed this experiment before with cheaper RadioShack quality cables and notices a much greater difference in favour of the optical cable, but assumed that was only due to the cheapness of the analogue cables.
Anyway, now I'm wondering if the DAC in the CDC-685 simply isn't as good as the one found in the RX-V2200. I did some quick searching on the net and the best I could come up with is that the CDC-685 uses S-Bit DACs while the RX-V2200 uses 96 kHz/24-bit DACs. Other then that, I really don't know anything about their DACs and was wondering if anyone could shed some light on this.
Since I prefer the sound of the digital connection over the analogue one, I will continue to use it. My real question is, is the reason the sound quality is better with the optical connection because the CDC-685 uses inferior DACs and could I expect a much improved sound quality from a high-end CD player's DACs?
