I notice that when I use the Bauer stereo-to-binaural crossfeed with these headphones, the signal path changes from Lossless to High Quality. Which, in theory, is the best setting for optimal sound quality?
Optimal sound quality is pretty subjective. It’s whatever sounds best to you. However, in theory Lossless is optimal quality. Having said that, in Roon 1.7 I could detect a very, very slight degradation of sound quality when I used DSP such as volume levelling or crossfeed. I don’t seem to hear that anymore with 1.8. The release notes suggest they optimized the code for the DSP engine so maybe that resulted in an improvement.
