This EtherRegen device seems like it would be better than 2 Sonore opticalModules to go from Ethernet RJ45 -> OM -> Fiber Optical Ethernet -> OM -> Ethernet RJ45. Simpler seems better to me but I have not heard either.
The Sonore modules that output USB is what I have heard and own and they seem simpler in the audio data flow.
That EtherRegen does seem like something interesting if you have an RJ45 input in your DAC with a built-in Roon Ready Media Server in the DAC, such as a Lyngdorf 3400 integrated. If you used the Sonore USB based output products on this Integrated you would be wasting money by not using the built-in RJ45 streaming of the DAC.
@grannyring Don’t you have the Lyngdorf 3400? I am demoing this with an external amp (SimAudio 860 or Luxman m900u) and the new to USA Yamaha NS 5000 ASAP.
Great info, thanks.
