Wow. Just -3dB of resolution loss was audible (from an AQ perspective) with older 861 firmware (vs. the 568.2/v2.5) before Meridian fixed the Direct and Stereo presets in v8.0. And with no adjustable gain for digital inputs in the 861, I can't help thinking that you are throwing away a massive amount of resolution.
