Maximum comfortable listening level for me is around mid-70s dB, but often I enjoy listening lower than that. One of the signs of quality hi-fi, for me, is that it can sound engaging at lower volume levels.

The Ultra's room correction works whatever power amplification you run it through.

Really? You sure? The specification don't mention any room correction function in this streamer, that always seems to be a function of the amplifier.
also surely you dont run power amplification through it but the streamer outputs to amplifier, or am I missing something here?
