  1. In a way it's a shame that Thunderbolt doesn't have a play outside pro audio since the Corning Thunderbolt cable does offer full galvanic isolation. The two strength members in the cable aren't electrically attached in the plug ends, and all signaling is optical.
  2. As far as I'm concerned detweakification is highly underrated when it comes to audio! ;-) Yet, however interesting it might be to systematically remove different aspects of your upstream optimizations to judge their respective SQ impacts in the context of downstream isolation and reclocking, I can completely understand why you'd rather spend your time simply enjoying wonderful music...
  3. Thanks for your update about your system! The Gustard U20 sounds like a really interesting piece to explore, especially at its price point. Would you say having the U20 in the path reduces the importance of the upstream tweaks (e.g., ethernet isolators, LPS on NAS, etc)? I haven't (yet) lost all hope that I'll be able to limit most of my effort to what happens right in front of the DAC. :-) That's exactly right. This is an active optical USB extender with a standard USB Type A male plug at the host end and a standard USB Type A female receptacle at the device end. Basically, inside each plug there's a VCSEL (vertical-cavity surface-emitting laser) lensed into a glass multimode fiber for the sending lane and a photodiode that reads the light from the receiving lane fiber, plus the other bits and pieces for handling the USB interface and driving said VCSELs and photodiodes.
  4. Could you comment on how the Corning cable performs compared to other USB cables you've tried in that configuration? And are you happy with how the SMS-100, Corning USB and U12 sound together? For full disclosure, I work for Corning and know the team that developed this active optical USB cable. The reason I'm asking is that I'm considering putting that exact chain together for my personal system and I'm very curious to hear what your experience has been. In other words, I'm neither promoting nor making claims about the cable... I'm just wondering how well it plays with the SOtM and Gustard. Thanks! Dayne
