How can a processor have "analog bypass" and 5.1 channel direct inputs (5.1 bypass) and have the volume control in the "digital domain". To control volume in the digital domain, you have to have bits to work with, and there are none in the Reference 30 in direct mode or on the DVD-Audio input. These are self-contradictory.

There are items such as the Crystal Semiconductor CS3310, which is a digitally controlled analog volume control. This volume control switches in and out discrete resistors in 0.5dB increments from -95.5dB of attenuation to +31.5dB of gain. Although interfaced digitally, it operates purely in the analog domain for volume control.

Care to cite your source of information for the comment that the volume control is in the digital domain?

Regards,
