I have also been using a Sonore music server from Simple Design for a few months now and have to say that I'm just as happy as Michel. The Sonore sounds great in my system. I recently had Jesus install the SOtM SATA filter, SOtM tX-USB PCI to USB audio card and the new Sonore signature power supply. These changes have really taken the Sonore to a new level. Maybe even more importantly, Jesus has been fantastic to work with. This has been my first experience with computer audio and Jesus has helped me all the way through it by email and with phone calls. I think you'd be hard pressed to find customer support like this anywhere else.
For anyone thinking about getting into computer audio, I highly recommend Jesus and the Sonore!
