The last tweak I did was to convert the Ethernet connection coming out of the switch to fiber, then back to copper, then I use a $400 Ethernet cable to the Kef’s, sounds better. I did the same thing in my reference system, but I use a $1000 Ethernet cable to my streamer and it sounds much better. Fiber and better cables make a big difference
Ethernet is galvanically isolated, so none of that matters:

Yes and no! If you read the article, you would have read info that made my point, and that is if you really want to clean up your Ethernet signal, you need to Gp the fiber route.
From your article:
Fiber Optic Networks: Eliminating the Electrical Path Entirely
For the most demanding environments, fiber optic communication provides the highest level of electrical isolation because data is transmitted as light rather than electrical current.
Key advantages of fiber optic networking include:
-
Complete galvanic isolation between connected devices
-
Immunity to electromagnetic interference
-
Elimination of ground loop currents
-
Greater resistance to lightning-induced disturbances
-
Much longer transmission distances
Thanks for the clarification
Do you have a “demanding environment”? And how do better cables that are not optical factor in?
I want the best cable for each application. After the copper-fiber-copper conversion, I want a good Ethernet cable. This AQ Ethernet cable was only $400, for my dedicated audio system, I put a $1000 AQ Ethernet cable and it does make a difference in sound quality
I can’t decide if this is intended to be humorous or not. I’m hoping it is.

Why do I feel a “war” coming .
I am in the Ethernet is Ethernet camp. I rarely spot spelling mistakes in Word documents 
The distortion I spotted on the LS60 was very much recording dependent , get a good recording they sang. I had returned the speakers before the update was released (my retailer has a 7 day return policy). So much so that if I hadn’t known about this I would have blamed old recordings
I tested them against JRiver , Tidal Connect etc to eliminate any Roon issues.

@Timothy_M - I’ve moved these off-topic posts to a thread of their own as requested.
I fear the worst.

And then they increased the price for the cable I already bought and it sounded better.

Is this already a case that warrants posting the Reddit rant?

I am very interested in any improvements to roon sound and will follow this thread. At present I use fibre from my main switch to my audio system. Imho this was an improvement. The usb cable is a wireworld platinum which separates the power wires from the data. I feel this has the potential to eliminate any induction.
Understanding how networking works is quite demanding.

But it does not come with a $5000/m price tag, so how good could it be?! /s

My distortion was on every song I played thru Roon, it didn’t matter, they were all distorted. The same songs after the update sound clean now
Progisus-that’s a start, but what do you do with the fiber once it gets to your audio room? Do you go directly into your server/streamer/dac? This would be the best option. Do you convert the fiber to copper then use a good quality Ethernet cable into your server/streamer/dac? This would be another good option.
Do you go into a switch then come out with copper? Not good, you will probably add noise. You want the less interfaces you can do after the fiber.
Buying a network for dummies book is like buying a dummies book on how to program in AI. Good luck with that, you’ll probably get the basics but I doubt it will teach you wifi 6e advantages over wifi 6 and how to take advantage them in building a mesh network both in wired and wireless installs
No it isn’t…
