Optical vs Ultra Rendu.

Is it worth the $696 more to go with the optical Rendu:


Over the standard (ethernet connected) ultra Rendu:


Has anybody compared these units, is there a notable difference in sound quality between these two?  Both still connect to the DAC via USB. 

sns - "Get good power supply for OpticalRendu, best you can afford"

Do you feel the LPS sold with the Rendu (bundle) is inferior? And

"At some point you may want to look into getting a switch rather than going out from relatively noisy router."

Any recommendations on a good switch?

Also sns you state: "OpticalRendu $1500 plus FMC $25 or so"

In this bundle it does not show any FMCs, so what is this for?



singingg - super interesting journey, thank you for sharing. I'm hoping to get as close to what you have achieved, but somehow, without 9 boxes. You've definitely taken separates to another level!


rbstehno - "It’s funny that people are worried about sq when they use usb to their dac. If you want to increase sq, stop using usb."

Interesting comment, but both Ultra Rendu and Optical Rendu use a USB connection to the DAC.

I also had a Wyred 4 Sound 2v2SE DAC that the owner (E.J. Sarmento) recommended to connect both his MS music server and a Roon Nucleus to via USB for best sound quality.

How do you connect?


Then to add more confusion, the wiring diagram on the Small Green Computer site show a simple fiber ethernet cable going from the router to the optical Rendu.


So, what is all the extra hardware seen in this Hans Beekhuyzen video starting around 2:05. Such as the SFP media converters. What is the difference between these two set ups and will there be any difference in SQ?
