I used to run my Logitech transporter from FLAC files loaded in a RIPNAS server into my 861. It sounded excellent but when I transferred to Sooloos from my MC200 using QNAP as the medium (files copied from Ripnas) the sound was noticeably better.

I now use QNAP and Sooloos for my main system and squeezebox access for other areas i.e. conservatory. To be fair although my current system with 861v8 and ID41 rather than v6 and ID40 does make a substantial difference my comments are still valid for the time I had the lesser hardware.

Hope this helps
