If my theory is right then I suspect industrial PTP switches will sound as good if not better than the Catalyst switches.. as they have to have a very tight PHY clock to support the Precision Time Protocol - which exists in part below the data link layer. I do not have a PTP (IEEE1598)  device to experiment with however...... such as a Cisco 2520.

Simon,.....very interesting to read. I have talked to the company in Holland today. The company that we buy our Cisco's from.

He send me this information,is it this Cisco 2520 you mean/talked about........

.......●   Cisco CGS-2520-24TC: Rugged Ethernet switch with 24 10/100BaseTX ports and two dual-purpose Gigabit Ethernet uplinks (dual-purpose Gigabit Ethernet uplinks allow the user to activate either copper or fiber media). There are two 10/100/1000BaseTX ports and two 100/1000 Small Form-Factor Pluggable (SFP) ports on board. The user can select two fiber ports, two copper ports, or a combination of fiber and copper ports. The Layer 2 LAN Base image is included.

●   Cisco CGS-2520-16S-8PC: Rugged Ethernet switch with 16 Fast Ethernet (FE) SFP ports, eight 10/100BaseTX/PoE+ ports, and two dual-purpose Gigabit Ethernet uplinks. The Layer 2 LAN Base image is included.

Aesthetics aside, is there any significant difference between the older blue models and the newer grey versions?

All I can say,.....Inside they look exactly the same,haven't compared them if there are some differences in soundquality.

I have one from 2007,it's blue. The one from 2009 is grey.

IF,....it is differences in soundquality, I think it's because you must recapp the older ones SMPS power-supply card. We have done it with one Cisco 2960,and after a "burn-in" period the soundquality was better. This Cisco was from 2007.

I am able to run an Ethernet cable straight from my router to my 272. Would that be better or does using the switch inbetween add some benefits?

Short answer,.....YES,a switch between router and your 272.....better❗ 

◾ Cisco WS-C2960-8TC-L

/Peder ???? 

Thanks Peder. Is this from listening or is there a known “technical” reason why? Not questioning your advice just wondering?

Your question needs clarifying:    does this mean you are only www.streaming (Tidal, Spotify etc) & iRadio ??

If the answer is yes then there is no point of having a switch.    If however your 272 is also local streaming from something like a NAS, Core or other local server,  then the switch makes sense as it manages data stream traffic between the three (or more) components,  and it might do a better job than the router.     As to if it sounds better,  that argument can go on a bit,     in my case it did for sure because at that time I had a crap router.  I carried on with a switch even tho' I have a good router these days,  the switch makes for easier/tidier cable mngt & I believe a switch has a better chance of getting optimum SQ. 

Hi Brian King,from listening......always❗ 

Technical reason can be interesting to talk about,.....but in the end,as I say, only listening advice ????????.

/Peder ???? 

Mike-B I stream Tidal internet radio and from my Unitiserve.

Appreciate the advice guys, and the general discussion in this thread, very informative.  Just pressed the button and bought a Cisco WS-C2960-8TC-L.  

OK  Brian,  congrats on the Cisco.   It goes in as per my diagram.   Enjoy

◾Mike-B,here we have different experience ????,I,and all the people I have listening to music with.......All hear a differens to the better with a Cisco 2960,even when streaming (Tidal,Spotify ect).

Strange that we have so different experience about this.

Yes Peder,  strange indeed if you mean that there is no server involved.   I cannot understand how a single one wire data stream connection between router & renderer ( router-renderer ) can be improved  by adding a switch in between them  ( router-switch-renderer )            

They have fans inside? Any noise audible?

i found also that tidal streaming is better with a dedicated switch, cisco or other switch, vs directly to my router.

Mike-B,agree,but it does.....router to Cisco to streamer,just streaming Tidal,no Nas,server ect involved.

Cisco WS-C2960-8TC-L has no fans inside.

Thanks!

OK I hear ya,   & Peder & his svenska forumites.   I don't understand why,  I wonder does the 'better' sound mean better or just different.     Hopefully an IT expert person can explain how adding another switch (the router is also a switch)  can/will improve SQ.   

◾ Mike-B ????,I have say this before,and say it again,...I always go for better in musicality,the music "flow" ect. Work with the method "TuneDem" from Linn,and also Naim but they called it PrAT when comparing things.

A friend who have worked in the store High Fidelity in Stockholm (Sweden), in the 80-ish a Linn AND Naim dealer.He have been at both Linn and Naim for education in how to do system-installations. It's the same method,but they have different name on it ????,.....marketing you know ????????.

/Peder ???? 

Peder,  you do not need to prove or reason to me why you hear what you hear, & I am very familiar with the Linn 'method'   All that is a personal/physical reaction to whatever you hear,  therefore it is subjective.     I simply want to know from an IT / data stream / computer expert if adding another switch in the data stream does change the streams packet structure or presentation,  and does this mean it is theoretically possible to affect the renderers SQ.

Mike-B,I just answer your question to me,...."better or just different".

And about the method TuneDem,to many haven't even heard about it,....and if they have,they have problem with how to use it. On Lejonklou's forum, it's a rule that you must use this method when compaering products,so everyone knows how to read what you are saying about a product. Because of that I explane what method I use, when I answer your question to me ????.

Simon, I get a price on mail today for this Cisco 2520, no fan.......the price was just under €2000:- (euro). What is so special with this 2520 vs 2960❓ ............I mean, it is not cheap like the 2960.

If this Cisco 2520 is refurbished and factory reset,is it then just "plug and play" or must you do some more advanced installation ❓ 

/Peder ???? 

Keep it in mind that both Uptone and SoTM are coming out with bespoke audiophile switches, both probably under $500 (my money would be on the Uptone). So you may want to wait before committing to silly money for military priced industrial switches.
