Anybody gone from ethernet to optical for connection to a streamer?

I agree ethernet cables make difference. Thread got me to wondering where optimum optical placement would be. I'm using just prior to USB renderer based on idea last segment of ethernet chain would provide greatest benefit. On the other hand, if converter placed just after modem, in other words first link in chain, may provide greatest benefit. The idea is any junk riding coax into modem, modem itself and first ethernet cable out of modem would be galvanically isolated, benefiting server. Problem then is EMI/RFI in house can enter after first link.  And then I could go further, keep present optical conversion, add the second optical setup prior to server. And then, we could only be so lucky to have fiber optical service from cable company. Even at this, ethernet cable within your house would be susceptible to EMI/RFI.
Ultimate setup, fiber feed all the way from cable company through entire ethernet and digital audio equipment throughout house having available fiber connections direct to optimized optical connection on dac.


Yes, I continue to say optimizing streaming solutions is the most complex undertaking I've yet encountered in audio. My experience is every single minute link in chain makes a qualitative difference. Relatively high degrees of improvement are available at every link in chain, and fast evolving innovations mean highest quality streaming never a stable situation.

Yes, optical is a big improvement. Can't say enough good stuff about the Sonore opticalRendu fed from a NAS device in another room. A good power supply for your renderer is also very important to allowing you to hear everything your optical changes will bring. 
Tons of threads on these topics here and on audiophilelifestyle. It's worth doing plenty of research to get a handle on it. Cheers,

My player has an optical network input, so does getting sonore rendu thingy make sense?

My best advice to you is to keep it simple. I have been down this rabbit hole, switches, filters, clocks ect. You can spend thousands but no matter what you do it's only going to be so good your at the mercy of the people sending you the stream. These devices can change the sound slightly but is it for the better?

I'm back to the basics and the SQ is the best it has ever been. Ethernet cable from router to server, server to DAC Shunyata USB Omega cable.

Only way you're going to know is by trying, the great thing about streaming is the wide variety of equipment and constant innovation.
