Man, since I ordered my DSD Sr. yesterday I think I have spent at least 10 hours on these forums reading and learning so much. This is such a great community.
Ted mentioned galvanic isolation many times with regard to the purity of the USB signal and why the Corning USB 3. Optical is desirable. I started doing my own research and wound up with more questions than answers and was looking to get some of your feedback.
Currently I use a USB split cable that has two independently shielded wires to carry power and signal separately such that if the DSD Sr. doesn’t require power input on the USB line I can remove the power component all together:
The only contamination I can think of in this scenario would be proximity cross talk induced at the actual USB header pins.
Which got me thinking- for ultimate galvanic isolation, what if I purchased the ifi galvanic isolator (link below) and used my split USB cable as the input. I could then use the Corning USB 3. Optical (link below) cable as an output to the DSD Sr. In this case the nanoiGalvanic3.0 would eliminate any possible power contamination and the Corning USB 3. can be driven directly into the DSD Sr. My only concern with this method is that I am not a big fan of the ifi’s REclock2/REgenerate2/REbalance2 nonsense, I don’t know what it is doing to the signal and would rather leave that heavy lifting to the DSD Sr.
Any thoughts? Am I crazy and should just stick with the split USB cable? Or does the daisy chain of USB Split Cable + Galavnic Isolator + Corning USB 3. Optical have some merit?
