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.

@high-amp

i will pinch hit for @soix

fiber media converter set (a pair is needed) - this is similar to what andrew at sgc has bundled

then get a short run of optical cable:

then you should use a filtered 5v dc power supply for the receiving side of the optical pair (don’t re-introduce switch mode ps noise back in on the receiving end)

jjss49 - wow, thanks for all that!
OK, so it looks like you can purchase a Ultra Rendu then add these media converters to achieve an optical connection.

But, if you purchase and Optical Rendu you wouldn't need these media converters as the Rendu is already optical. Am I reading this right?
