Hi Rob - it's good new about the Olimex helping with RF issues on the SD input, but alas this still seems to leave issues for those of us who want to play 24/96 and 24/192 material through the HD input. It's a real fankle unlplugging and plugging in USB leads!
Do you think this
http://ifi-audio.com/portfolio-view/micro-iusbpower/ USB power supply is a good way to go? I know it's made by another manufacturer, but as far as I can tell reading through the sales-talk, it does claim to clean up the 5V supply considerably, breaks the ground connection between the DAC and the computer, and has a 3-stage 6th order RF filter. It will pass 24/192 and it does work with the HD input of the Hugo, which means that it could be an alternative to the Olimex that would work for all resolutions, and with the HD input.
Or would a USB to optical s/pdif converter be a better way to go?
'Scuse the questions, it's just that the Hugo is so wonderfully good that I want the best way of listening to my hi-res studio masters I can get, and I'd really prefer not to have to fiddle with cables.
