I’m used to linear phase filter since I have been listening to it for all these years.
Many years ago I asked some users to participate in a blind test for a linear phase / minimum phase setting (not the current QRONO d2a). Excluding some who did not think there was much difference or did not pick a preference, roughly half preferred linear phase, and the other half preferred minimum phase.
There was also a matter of audio reviewers preference that does not concern users directly, but I believe is more important for manufacturers. At the time I did this survey, I found multiple audio reviewers who preferred minimum phase. Other than MQA Labs, I think there are also manufacturers that preferred minimum phase. Last time I checked, Roon DSP engine default was also minimum phase.
A Lumin P1 user e-mailed us saying QRONO d2a improved “clarity, calmness, precision” for him.
Anyway, I think having a choice is the most important thing.
