Sounds interesting. I will definitely follow your progress.

Please correct me if I'm wrong......

1. I was under the impression that I2S was strictly a transfer protocol for PCM data, not DSD data as would be required for SACD playback. Is that incorrect?

2. Are you not going to have to dissect a commercially available SACD player to get the transport and the necessary circuitry to decode the SACD data from its protected format?

The Denon DCM-27 has digital outputs too. Not sure if it's a quality unit to add to the list.

As do most decent digital players these days.......the thread is about why the better players don't have digital inputs.

That could very well be but the APL is pretty far from a regular CD player. They have to write their own control code and you get a second remote.

Oops, sorry about that!

The second remote is very important for those who own sofas of course. allows for convenient track skipping while plumbing the far depths of the cushions for the first remote.

True...

While you can change tracks with the second remote it is mostly for choosing the inputs (there is also the option of a ADC input and a squeezebox built in on the more expensive models) and changing the volume. The evils of stepped attenuators have finally been banished!!!

1. Whatever the case may be, if I take everything from the DAC forward out of an SACD player I just have to hook up some leads to the same inputs on the Opus. Whether or not this will work on the Opus remains to be seen. The new boards will be ready next month so we will see then. If not, I will just output the player's DAC output direct to the amp, eliminating the output stage.

2. Yes, of course.
