The majority of DACs do not have galvanic isolation on their USB receivers. The ISOGEN will provide that function for those DACs. Some DACs, e.g. the Schiit DACs that some of us here use that have the Gen 5 USB feature, have very high-quality galvanic isolation already built-in to their USB receiver ports. Schiit also uses quality isolation transformers for this rather than the usual opto-couplers; the isolation transformers provide higher levels and quality of isolation.

"It is all about jitter/phase-noise traveling on ground planes and causing variation in clock edges, both overall and inside the chips. That’s why our differential isolation and reclocking works. Of course John [Swenson] will explain this properly in 10+ pages…" When John publishes his paper (which I understand will include data), as mentioned previously, I will reference it, but here is some additional information with respect to "methods and materials": "John recently acquired one of the most sensitive timing analysis systems ever built, the Wavecrest DTS-2079. He just received the boards he designed and the parts to populate them to create the required input module so he can use the system for measurement of jitter and noise on the I2S lines inside DACs. And he will be able to produce comparative graphs with variables like EtherREGEN and other things upstream. While these will not be measures at the analog output of the DAC that the skeptics demand, I feel stongly that showing differences on the I2S lines inside a DAC will be every bit as valid in proving the existence of these effects and the efficacy of the technology we are employing."

To me, if ethernet is so adversely affected by these problems then dont use it directly. Use a computer and attach your DAC via USB. USB has its own issues, but they are measurable and can be dealt with. |

EtherREGEN on the way!
Maybe I’m being myopic here, but here goes...
Sending a file to my computer from the NAS thru a myriad of noisy routers, noisy switches, Ethernet cables picking up stray noise, etc, should not alter the file at all since the transfer is using the bulk transfer protocol - there’s robust data checks with correction. The file should arrive at my computer unchanged - a perfect copy. So the beauty of this device would not be for the file transfer itself. Rather, it would eliminate noise that is generated by all the other devices from getting into my computer via the cat 6, correct? Last edited by Cohibaman; 11-22-2019 at 01:46 PM. |

Let's wait until the white paper is available, gents.

Again, not trying to dispute anything here; I’m trying to understand.
