After some head scratching I remembered that a technician had added an extra switch to my home network in the past week. Then I realized that he had changed the data flow.

Initially, the flow was:
Street cable->router->switch->component

The technician had changed it to:
Street cable->router->switch->switch->component

Notice that the signal now went through two switches intead of one. The second switch is on another floor. Had I not used an Ethernet cable of different color to connect to the upstairs switch it would have been very difficult to find what the problem was.

Anyway, changing the flow to the original set up fixed the issue.

So... my experience leads to believe that your problem could be related to the switch that you are using. If connecting your component directly to the router fixes your problem, there is your answer. I personally have not noticed sound changes when using cat 5e or cat 6 Ethernet cables.
Very informative post, many thanks!

Yes, its clear that adding my Ethernet switch added some noise to the system that was both discernable and unpleasant. The cable is adding some sort of wonky noise or other distortion component, though, because I went back and just put one 1M Blue Jeans cable into the router directly from the Mac Mini, and heard these problems in the high frequencies. It was audibly quieter than the generic cable, I presume due to better construction and shielding, but the highs are too unpleasant to listen to, at least presently.

Each LPS got an Audience AU24SE MP power cord. Lastly, the network got AudioQuest Diamond Ethernet Cables.

There are still other tweaks I can implement such as Linear Power Supplies for my Synology DS-3018XS NAS, Netgear Nighthawk X10 Router and Cable Modem. I may also add an audiophile switch but frankly, the Nighthawk X10 works and sounds so excellent with its 6 Ethernet LAN ports, I’m reluctant to add another switch in the chain when it’s really unnecessary.

Hi Ken,
Thanks for your post for this discussion. Yep, I read the Audiostream review of the GigaFoil V4 from info provided by Jim (Still-One). For The Love of Music is using Keces LPS's, too.

With the very high-quality components of your digital front end, GigaFoil, two Keces LPS' and AQ Diamond Ethernet cables and the Audience PCs, I would expect it would sound very good indeed.

I'm trying to do this on the cheap, though. I would estimate two Keces P-8 LPS, the GigaFoilV4, 2 X 0.75M AQ Diamond Ethernet cables & two Audience AU24SE MP PCs would cost approximately....$8000?

It must sound fabulous...

Blue Jeans Cable is responsive to any problems or questions as they stand behind their products —

"Here's something you won't find anywhere else: Ethernet patch cords for Cat 5e, 6 and 6a, with individual certification testing and a full-color test report printout on every cable. The great majority of Cat 6 and 6a Ethernet patch cords sold both in stores and online are non-compliant--our tests (see our article: Is Your Cat 6 a Dog?) show that very few of the cables which are sold and labeled as "Cat 6" comply with the specification, and many "Cat 6" cables don't even pass Cat 5e! We assemble our Ethernet patch cords in the USA using American-manufactured connectors and (in the case of 6 and 6a cables) American-manufactured, Belden bonded-pair cable stock, and we test every last assembly on a Fluke certification tester, so that you can be assured of really getting the performance that you've paid for."

You should contact them with your findings

Best of luck!
Ron

AQVox SE Internet switches, Keces P3 power supplies, and Gigafoils! You guys are frigin' killing' me!
I just ran new Cat6A cable to my router, to shorten my cable to my Lumin S-1, so that I could get away with a .75 meter Diamond ethernet cable. I thought I was done! I should know better! Damn it!!!

My experience: digital and analog are very different. With digital, keeping it simple or KISS works for me.

You are slowly arriving at the same conclusion i did. The culprit in my case was the FMC's not your Ethernet cables. When you first introduce the FMC's into your chain, what is perceived as an improvement in sound quickly turns into "a step backwards" as you say. I think the FMC's introduce the harsh highs you are experiencing by injecting noise from the conversion. Try removing them from your chain and listen for a few days and don't be surprised if the "harsh" is gone. A better fiber to copper conversion could be achieved via the GigaFoil v4. Looking past the industrial look, the execution and quality of the components seem solid and the positive reviews continue to roll in.

True enough! Ok, Gigafoil, power supply, and AQ Diamond Ethernet cable on order! We shall see...

Thanks for the comment, Sircharles, appreciate your comments regarding the discussion.

"I think the FMC's introduce the harsh highs you are experiencing by injecting noise from the conversion."

Respectfully, though, that's not the case, at least in my system, setup and room (everyone's system, setup and room are different, so YMMV).

The FMCs clearly lowered the noise floor, increased the airiness, spaciousness of the presentation increased and smoothed out the extension of the highs/treble, so they made a notable improvement in the sound quality when I installed the run of fiber using the FMCs compared to the direct run of Cat 7 Ethernet cable to the Sonore.

When I took out the Ethernet switch and Blue Jeans Ethernet cables, I got back to my gorgeous-sounding digital streaming front-end. When I put the back in the BJC Ethernet cables and Ethernet switch one-by-one, the strident highs and uncomfortable treble came back one-by-one and became cumulatively worse. The el-cheapo, generic Ethernet cables sound more pleasant than the BJC Ethernet cables, so its possible the BJCs need some burn-in....

I'm sure the GigaFoil V4 is great, but I would still need a long (~7M) run of "audiophile" Ethernet cable either before the GigaFoil or after the Gigafoil to the Rendu, and I simply can't afford that. Plus there's the $500 cost of the Gigafoil.

So, far, the $65 investement in the FMCs and Tripp-Lite optical fiber have paid big dividends in audio quality over the 7M run of cheap Cat 7 Ethernet cable.

The experiment continues....

The power supply for the FMC is important. The model of which FMC is used and the choice of wavelength also affect things. Now I recommend users to use 1310nm, based on subjective feedback from demo visitors.

We have native (fiber) SFP support in our product without requiring the use of FMC, and it is powered by our audiophile LPS, and another manufacturer is releasing an audiophile grade FMC.

My point is that fiber conversion does not have to be bad.
