Thanks for the response and I look forward to the release. This is one area I think I can improve my sound and will give a hard look at the DAC-9. I assume it will be near the Nuforce version of the oppo player specs? Or will it be better?
We have explained here in Audiocircle and other forums that Oppo BDP83 Nuforce or SE, they are not a DAC. The design specifications are completely different.
In a DAC, we have to look at data (SPDIF input) acquisition and processing. In a player such as Oppo or CDP, we are not dealing with data acquisition, but playing back stored data which are deterministic.
Also, Oppo's output stage must handle everything under the sun from Redbook CD to DSD SACD, while CDP only deals with 16-bit, and the DAC only deals with pure PCM 16-24bit.
In a high end DAC, the strategy is that it would have to deal with rejecting or becoming immunized to the incoming data jitter, and a lot of effort is focusing on this section of the circuit. While for a pure player, such circuit is not necessary.
