Here is my setup, I am currently running from laptop to SP2000 then TOSLINK
optical out to Hugo M-Scaler / Hugo TT2. XLR balanced to MHA200.
No RFI noise. Sounds tremendous
. Looks crazy, but the SP2000 is not converting to analog in this arrangement. It is only converting USB data to Optical output to the Hugo M-Scaler. This is reducing or eliminating jitter. The laptop is normally on my desk a few feet away. Why bother with the SP2000? I can now play anything from Foobar2000 or any source from the laptop and the SP2000 will convert the digital audio into optical output.
