Cams,
Welcome to Red Wine Audio, Squeeze Box, Audio Circle, and hi-end audio!
Some can't believe/accept that the future of hi-end can be in something as inexpensive and easy as SB based PC audio. I guess it's not exclusive enough (or maybe they need to rationalize the $$$$ spent on CD players, transports, and DACs.
Best to p.m. Vinnie about European service.
I'd try the stock SB3 in your AV system first to gauge its quality vs. the rest of your system. (Realize that the SB is 2-channel stuff.) If you go ahead with a 2nd one, it can be ordered from SlimDevices and shipped directly to Vinnie for mods.
Hope ripping and software setup goes well with you.
