That's a little odd - the HD input should sound warmer than the SD, so I can't explain that. Mobile phone sources are effectively isolated, as there are no ground loops via the mains, so perhaps this has something to do with it.
SD input sounds closest to your laptop?
When your laptop is running on battery power, do both SD and HD inputs sound the same?
Or the phone doesn't like the extra current draw of the galvanic input?
I’m gonna test the HD and SD on my laptop tonight but the HD input with 10 ferrites sounded close but not identical to optical last time I tested usb which was 3-4 days ago.
I’m thinking the phone may not like the extra current draw but who knows?
Does it make a difference that both my phone and TT were placed on my bed when switching inputs?
Was listening to both IE 80S and IE 800 and both times the SD sounded more relaxing.
