Basic switch....should I upgrade?

@scottfraser NAS storage makes sense. As far as recording and mastering…there are so many poorly recorded albums out there that no amount of fixes by the end user/listener in their system can address these issues be it mastered over Ethernet or direct.
Studios, at least some, also use basic cables and mid fi monitors. Then there are recording studios and engineers that are so anal about the quality of the product they put out that they use the best possible gear. What does all this mean to us as end users? In my opinion - absolutely nothing. We’ll pursue getting the best sound we can and that includes fixes and tweaks. 

Now we tend to get carried away in the process and go deep into the woods but still see just a tree or two as opposed to seeing the entire forest. That’s a good point to pump the breaks and reassess…do I continue to add crap in an attempt to make a mediocre component sound better than it possibly can or do I stop and just upgrade that component? Realizing when that is is what will get you to the next level. We’re all guilty of missing that mark…

Didn’t mean to get philosophical here but that’s about how I look at it. You may see it differently.

The first switch was a Cisco 2960. Had mods done by audiophool.nl

Last month bought a Cisco SG110D switch. I needed one with a small footprint. Have sent it to Fidelity Audio in The UK. They have put one of their C4Mk2 clocks in it, and changed a couple of capacitors.

@jerrybj Thank you. Interesting.

You have done some interesting stuff. But I haven’t heard you say anything about the differences you have hear in your system as a result of your changes. What have you observed? Reduction in noise floor? Dynamics? Small difference, big?

The amount of things you guys are trying is astonishing. But none of it works, and a lot of it is counter to how Ethernet works. For instance, for audio listening (not two way like voip), latency is irrelevant. The change in latency matters however, and if packets arrive out of order. Another things, the only possible outcome of taping batteries to an Ethernet cable is that you introduce CRC Frame errors, which the will force the switch to discard the frame, and higher level protocols to trigger a retransmission. 
 

pro audio applications use enterprise equipment, not made up cures but introducing voodoo into the chain, and adding things. 
 

maybe it is just me, but in general for my audio setup, I like to Keep It Simple, the fewer components, the better, since adding will only add to the signal, which means you have modified the recording in transit from source to speaker, and that is not audiophile grade.
