I have a ubiquiti set up including three switches, I wont be swapping them out any time soon for a perceived difference in the slight texture of a symbol or what ever.
If you want to enjoy your music more, get half cut and turn the volume up.

I have a white 1gb model and a 100mb blue one.
I have a CG but I’m not sure why you are asking.
I guess this is a perfectly acceptable answer in certain audiophile circles

Couldn’t we achieve something similar with port-based traffic control, which I guess is an available feature on Catalyst 3560 ?
Thomas, perhaps you can explain what you are referring to with ‘Port based traffic control’?
Switches do port based traffic manage to of most frames.
There are however broadcast frames, ARP processing, and multicast group frames which can load the port irrespective of unicast data going to the specific host.
Creating a separate subnet from the rest of your network with the appropriate helpers and routing protocol support can reduce the above and consequential processing noise from the host (streamer) network stack and processor.
Perhaps he’s referring to port isolation. Unifi recommend this to cut down on unwanted broadcasts over wifi from ap to ap.
@Simon-in-Suffolk,…I understand you,.you have written hundreds of explanations on this.
So,.somewhere on the road you give up in the end.
But these “basic” questions will recur all the time,.this is due to the fact that there will be new members here.
• That is why I have suggested before,.that we should have a Music-system Installation-thread as “sticky”.
Then you do not have to repeat,.repeat and repeat the same thing all the time.
Because when you Simon,.and others with high competence in this field do not cope with writing anymore,well then a key knowledge source disappears for the forum members.
So Thank You Simon,.for that you still have the strength to write technical explanations about Cisco and other switches etc,etc…

Mike , after the Zoo and the coffee, you can buy the cisco 2960 switch.
Well hidden, your wife will not notice it but your ears very very probably.

Fair point
But those data specifications are pretty much the same as any off the shelf basic consumer switch at PC World might have - essentially those are the specifications that a regular gigabit switch supports.
For our uses I see no support for IGMP Snooping and which IGMP version is supported which is far more relevant for good performance with handling multicast groups.
I suspect it simply blindly broadcasts all groups out to all ports - which is bad for Ethernet data processing noise isolation.
I really think of lot of these devices aimed at audiophiles are made to look rather bling like - but not really that effective for the jobs they are expected to do over and above a basic switch.

You are probably right Simon. I don’t know. I have seen only one review on it for now… The aqvox se, which costs 800 euros, have some contradictory reviews also. Some say it’s the best they have heard, other , like stereophile, found a minimal improvement.

I would say the Uptone switch will be a different creature from the other audiophile switches if the other devices that John Swenson has engineered are anything to go by (all very very good with no absurd claims). And both he and the owner of Uptone have had Cisco 2960 switches in house to compare and breakdown (and both admit the Cisco 2960 was the best switch they’d heard before designing theirs). That said, I have no interest in it as I’ve gone to fiber optical ‘bridges’ for both systems. It would be fun to compare though.
I’m using a Cisco 2960L-16PS as the main house switch - it’s 1gb and very good sounding and the largest fanless Catalyst one can get. And in the office, I’ve set up an optical bridge to the UQ using the SFP out on that main switch to the SFP in an older 2960-8TC 10/100 switch. Works a treat and much better than the consumer FMC’s with their noisy power supplies. Still not as good as a pair of Sonore opticalModules though, but much cheaper - used Cisco SFP’s are about $5, the older switch $30 and the newer 16 port one $150, used.

I had the bad luck to listen to this switch this afternoon. Unfortunately I realized I need to further upgrade when funds become available.
I was amazed that it even outclassed the already good seperation of the Melco.
The test setup was as follows…
- Melco
- Ansuz Switch
- Chord Music between the ND555 and the Melco or the switch.
The setup with the switch was to have it connected to the Melco and have the ND555 directly connected to the switch as well.
What happened. Better transcend between notes, more 3D, cleaner sound. No positive or negative effect on tonality of the music. I had hoped to not hear the significance and realized that now listening through Tidal will even further close in on listening through the Melco as a lot of the other things are gone…
I also took a Chord Music cable home to test it against my Audioquest Vodka. So let’s see what happens in the next days. I will of course write about it as good as I can.

hopefully Bert proved the contrary…just after your post. But i know Tiberio, you don’t believe…
I think everybody serious about getting the best quality for streaming is obliged to listen to this device themselves.
i believe you Bert, unfortunately. However i am not prepared financially to upgrade today in a 2k switch and 8k ethernet cables. It’s the price of the upgrade to an nd555. Or a melco n10…
Step by step for me…

@BertBird,…Very interesting,.but you used the Chord Music-cable too,so then the difference is even bigger.
It will be interesting to take note of your impressions at home of Chord Music vs Audioquest Vodka.
I have an Audioquest Diamond and three Vodka,.but I’m not saying anything about what I possibly think,before you have reported your impressions.
• BertBird,…Another question,.when I look at the picture you added in,see below…
That several ehternet cables are plugged in with a gap between.
I do the same thing,.see picture of my Cisco…
The reason I connect the wires with a gap,.is that I think it sounds a bit better.
Do you think it is something that your trader also thinks,.when he has plugged his cables in the same way,with a gap.?
/Peder🙂
i feel that Anzus switch is probably better than cisco 2960, because the sound with my nds to cisco or nds to melco is the same. In your case, nd555 to Anzus sounds better than nd555 to the melco.
