One thread over on the General board states that tRio can be configured for variable volume control, and that the front panel knob as well as the remote work properly to adjust the volume.

That thread seems to hint, however, that variable volume control is only available for Line Out (and not for speaker/amplifier outputs).

What is the real status of tRio? Does it support variable volume for amp'd speaker outs, Line Out, both, neither? What do you have to do to configure tRio to support variable volume, since it appears to be a switchable feature?
