Lumin X1 Fiber Optic Network Discussions

While I wait for the EtherRegen I am still using the TP-Link Gigabit SFP to RJ45 Fiber Media Converter.
Previously when I placed my ear up to my speaker I have always had some residual buzz, albeit at a very low level. I have always attributed it to using tube amp(s).
But, I just tested it again and there is absolutely no buzz what so ever! The only thing different is going from the ethernet cable to the Fiber cable.

You must have a good feel for fiber vs copper from all the feedbacks. Which do people like better in general?
 
I have the impression that from those who tried both fiber and copper, more people preferred fiber. Of course there are also users who do not like fiber. You'll have to try both to to see what you like.

Just make sure do not connect both to the network. Forming a network loop will bring down your whole network.
 
I am really diggin' the fiber cable over the ethernet cable with my Lumin X1. There is so much more depth and width to the music. Plus I am hearing little subtle background instruments that were buried previously in the mix.

I also have added a EtherRegen.

What fiber cable and switch are you using?
 
I am now using the Uptone EtherRegen switch before this I was using the TP-Link switch below

TP-Link Gigabit SFP to RJ45 Fiber Media Converter | Fiber to Ethernet Converter | 10/100/1000Mbps RJ45 Port to 1000Base-SX/LX SFP Slot Supporting MiniGBIC Modules (MC220L)

I had been using these modules

TP-Link Gigabit SFP module | 1000Base-LX Single-mode Fiber Mini GBIC Module | Plug and Play | LC/UPC interface | Up to 10km distance (TL-SM311LS)
Which I think are great.

And this fiber cable

Singlemode Duplex Fiber Optic Cable (9/125) - LC to LC - Yellow

All of this was purchased via Amazon.

I have just ordered a couple of the Finisar SFP FTLF1324P2BTL modules. I could swear that I read somewhere that it is a preferred module? Can anyone confirm?

I heard in an ER thread that a mobile router/modem pulling signal out of the air and connecting direct to the streamer sounds better than all ethernet connection. He has two ISP, one for his audio and one for the rest of the house.

Is there an improvement in sound if the fiber switch is powered by an external LPS?

in theory it should make absolutely no difference -- when the signal is converted to light at the fiber switch all extraneous electrical noise is eliminated.

in other words, transmitting the signal directly to the X1 via fiber eliminates the need for an LPS ...or, any other upstream noise mitigating device / dongle.

But the LPS may affect the conversion to light itself.

Indeed, IN THEORY. Now do the test in reality, and we talk.

There is indeed no noise transferred in the fiber, this is the basis for isolation. The remaining questions are, whether SMPS pollutes AC, whether your other analog components care about those, and if they do whether they make an audible difference to you in your setup.

Wouldn’t any noise in the signal also be converted into the light stream, and then reconverted back into noise?
Click to expand...

no -- only signal voltages above or below a certain + or - threshold representing the 1s and 0s are converted to light and then transmitted according to ethernet protocols which mandate error checking and correction. thus, the signal received and converted back to an electrical signal is only the intended signal ... sans the upstream noise.
