I'm using 2009 Macbook Pro with a 1TB Hibred Drive and 4Gigs of RAM and Peachtree Audio T1 USB to SPDIF (I think this is the weakest link) and the then feeds the Lyngdorf DPA-1 "digital in". My FLAC files are on a QNAP NAS. The digital cable and the USB are both DH Labs Silver Sonics.

As I said a difference can be heard, but the sound is VERY good! I do see Roon as the future interface. It's the hardware that's my issue. I'd like to have a dedicated NUC, as my Macbook has iTunes running my as a video server. I'll also get a better converter for the USB to SPDIF.

Perspective is required here. I'm just doing a test drive and I don't have an optimum equipment setup. Given that, Roon sounds terrific.

Control:10, TwinStore, Lyngdorf DPA-1 Preamp, Linn Klimax Stereo Amp, Piega TC 70X speakers, QNAP TS-451 8TB.

Roon setup (temporary): 2009 Macbook Pro with a 1TB Hibred Drive and 4Gigs of RAM, Peachtree Audio T1 USB to SPDIF. FLAC files are kept on the QNAP TS-451 NAS. I use Rosewill (Newegg) Cat-7 Ethernet Cable on all connections.
