You can still use the ultra for volume with the new dac just set to full volume.Thank you! Currently my Ultra acts also as Subwoofer mgmt and Pre-AMp. When I use ULTRA volume control, both volume of main speakers and subwoofer change. But If I buy a better DAC and connect it to ULTRA and then DAC to AMP, I guess the volume control may be done by DAC, and volume for SUb will have to be done separately (as it is connected to ULtra).
