Posh switch - another cause of Audiophilia nervosa?

Posted by: hungryhalibut on 17 November 2016

There have been various threads recently about posh Ethernet cables and mention has been made a few times that plugging them into an el cheapo consumer switch like my little Netgear might not be getting the best from them. 

The idea of a pro switch was a bit scary as I'm something of a numpty and want plug and play. Then I discovered that pro switches could be used very simply if required. 

SiS has mentioned the Cisco catalyst 2960 as being very good indeed, but at a price of course, like over £300. However you can pick up used ones for much less and my eBay purchase arrived today. It has a proper mains lead rather than wall wart, and amazingly after a minute or two it just worked. I was rather astonished by that, as computer stuff rarely runs smoothly in my house....

It's been warming up for a few hours and it will be interesting to see how it does and whether there is a difference. It's certainly built like a brick outhouse and the post leads go in with a reassuring thunk. 

Let's see.

As I posted previously to that comment,  the app is far far away from a reliable indicator of anything at the moment  " ......... an issue that I'm working on in the beta group,  the app has random response variables"

Hello Simon !

It's Peder from Sweden.I must thank you for the recommendations of the Cisco 2960,I have write

about it in a Swedish Naim/Linn-forum.

 

I have also told them if they want to read more of tecnical questions and other things about the Cisco,look for your inputs on the Naimforum.

 

A forum-member in Sweden ask me one thing,and I must ask/take the question to you.He said to me that

the Cisco WS-C2960-8TC-L are in at least 3 versions,called V01,V02 and V03 and he ask me what

version who is best.

 

Have you any ide about that,I promised him to take the question to you.

 

Ones again,thank's for all you have write about the Cisco,I have learned a lot,and I promised you,I have

read every word :-). And a Love my Cisco-switch 2960.

Best regards

Peder

 

Hi Peder, you are welcome. I posted details earlier in this thread - I use V02  see below

I suspect it makes no difference though, and unless people know how to log on to the switch and execute a show version command on the console we won't know what versions others are using.

 Now here's a question, would a Cisco 3560 sound better as it's a POE switch and therefore would have a bigger power supply built in.

Posted on: 07 January 2017 by Simon-in-Suffolk

Yes I suspect its worth a try - its a Catalyst switch that supports PTP - they key aspects that drive the performance in my opinion, rather than the power supply. As I have said before with these switches I really don't think the power supply has much if anything to do with the performance boost many of us  hear - i think that is more for the cheaper consumer Netgear type devices

I'm finding greatly increased clarity at low volumes too. Very happy indeed with this £60 upgrade!

...and a new razor like precision in the placing of instruments within an expanded 'out-of-the-box' side-to-side and front-to-back soundstage.

How can this be!?

All the discussion on this thread has prompted me to do what I was told to do in the first place, which is to hard wire our 272 to the BT hub and not use WiFi. There's no posh switch (yet) but just with using Ethernet cable, everything is quite a bit 'better'. There's no going back now which means a not so simple cabling project but Mrs NewNaim16 is in total agreement. Methinks one of those posh switches is next.

That's another lesson for me in how worthwhile improvements can be obtained with little expenditure. And of course taking best advice in the first place - even if I don't really want the inconvenience!

I would have thought a bigger power supply might be noisier, therefore worse sounding? Then again, if it's POE, doesn't that mean it has no PSU of its own? I notice some 2650s are also POE, but I'm not sure where you would take the power from if you used one.

No, POE means it can supply power to POE Devices

Ok, I assumed it meant that the switch was powered by POE.

The effect of adding the switch was subtle but easy to notice. I thought the bass went a bit tighter and a little leaner, both of which sounded good to me. Unfortunately, this was accompanied by a ringing, biting edge to the treble which put me somewhat in mind of the DAC/555PS.

You can’t argue with the detail, resolution and sheer crystal clarity of the presentation but it goes all HiFi-like and you start thinking of system parameters rather than the music it is playing. The NDS put paid to all the HiFi and just left the music behind some years ago. The last two days have been a trip down memory lane and a reminder of why I settled where I did.

Putting back the original bog Netgear with its wall wart restored the balance without, it turned out, losing detail so much as shifting the sound balance - and most important of all, put the treble back in the soundstage rather than surging forward and trying to bite my face.  One cannot and should not discount the role of the room. I wouldn’t be surprised if that was the most significant contributor.

Having spent some time critically listening today and doing a back to back, I am left wondering if what might seem like more detail might just be a spike of emphasis at that frequency. Not so much more detail as simply a different balance?

£50 wasn’t a huge risk and I’ll keep it as a spare for data. The feedback on this thread had me thinking it was a foregone conclusion. Just goes to show how easily you can be swept along. No harm done though.

Harry,

My findings exactly!  At first, like you, I liked what I was hearing but became increasingly disenchanted as the weeks passed; so much so, that I have now gone back to my Netgear GS105 and much prefer it.  It is warmer and fuller sounding than the Cisco and in the context of my system displays a more even tonal balance.

Like you, I initially thought the Cisco was more detailed but I now feel it achieved this impression by being leaner, particularly in the bass, thereby emphasising the top end which could make it sound 'edgy', particularly on vocals.  The same information is delivered by the Netgear but in a way that sounds preferable to these ears.

I've found the Netgear has less width to the soundstage but makes up for this with a greater sense of depth.

The Netgear is definitely a case of more music, less HiFi in my system.

So, another 2960 will soon hit the market!

Cheers,

Ian

I run HP 1810G-8 & Qnap NAS both with external linear power supply & seriously think that changing to Cisco with internal power supply makes no difference but please let me know if I should try one? Grounding with proper ethernet cabels is impacting as well.

Well, I bought Cisco 2960: done 2013, SW 12.2.(55). Based on few hours comparison to HP & HDPlex I'm disappointed. Cisco is more flat = not so dynamic & piano & cymbals does not sound so natural = how long  & how instuments sound. However, Cisco is smooth & can be upgrade compared to some switches.

Let's see when I listen more but so far I'm not joining the Cisco fans. Still listening but quite sure that Cisco goes back to ebay.

Cisco myth Busted !

Simon,

If you wanted to combine the sonic benefits of the Cisco 2960 with gig Ethernet to support other devices on the switch, is there a more recent model that you would recommend worthy of investigation? I appreciate these won't probably be £50 second-hand upgrades, but I wouldn't want to sacrifice gig Ethernet, nor do I want to introduce a lot of kit just to serve the hifi.

Thanks, Adrian

Posted on: 18 January 2017 by hungryhalibut

The idea of a separate switch for the stereo is to isolate it from other traffic. So the files go from the nas via the switch to the streamer. If you start introducing other stuff you start to defeat the point. Perhaps connect two switches to the router - one for the Naim and one for the other stuff.

Posted on: 18 January 2017 by Mike-B

I'm not sure it makes much difference & have never tried it,  but to me it just seems the right thing to do.  I have a hifi switch - NAS>Switch>NDX -  running off one branch from the wireless hub & a separate branch to the study/office switch 

Posted on: 18 January 2017 by ChrisSU

I would go with HH's suggestion. Then a 'posh' switch for audio costing £50, and a regular consumer grade Gigabit switch for everything else costing £20. A Cisco managed switch with GB speed costs hundreds. Having said that, do you actually need GB speeds?

Posted on: 18 January 2017 by Adrian_P

Yes, I appreciate that, but I already said I don't want to introduce a separate kit just to serve the hifi. This wouldn't work for me anyway as my router is in my study and connected to the sitting room downstairs via a single run of Cat5E running outside the house and I currently have switches at each end of that cable. There is other kit upstairs and downstairs apart from the NDS that can use gig Ethernet. Not ideal having the shared traffic running over the same cable, perhaps, but that rarely happens in parallel.

Hi Adrian - I have only observed the benefit on specific Fast Ethernet switches - if you use a GigE variant I can't say how that sounds in my setup.

Clearly there is a difference that most are hearing - many beneficial - some not. Of those that are not and have commented  some are finding it sharper or more 'hifi' -and  some are finding it smoother - so feedback on lack of success  seems not to correlate clearly  so it might be due to other reasons..

But don't spend a lot of money until you try it first

I very much doubt there are many domestic users who need GB speeds, and if you're one of them you must be using a lot of data hungry devices. In which case maybe there's all the more reason to consider isolating your audio gear with a separate switch.

Posted on: 18 January 2017 by Simon-in-Suffolk

I must admit i don't get this 'isolating' my separate switch concept. Switch by definition is data isolated on all ports - unless broadcast traffic is being sent - and that will go to all active switch pots in the home network subnet.

So by all means create an audio specific subnet if you wish - but I guess that will be beyond most home users expertise and home user equipment - but even then you can still provide a common switch as long as it support VLANs

I was thinking of any interference that might be picked up from other devices as much as data itself. Would you happily connect PCs, TVs etc to the same switch as a streamer and/or NAS? If so, doesn't that make a mockery of the idea that fibre optic links have a use in isolating streamers from other noisy devices on your network?

I was told that a separate switch was best practice so that's what I did. I think it was that Mike B fellow. 

Posted on: 18 January 2017 by Gandalf_fi

Yes, separate switch is a best practice. I have done comparison between all my house switch in techical room vs. separate in close connection to NAS/NDS & the difference was very clear.

Wot ?? it wern't me, it wuz 'im sir, 'e did it.  

I have separate switches for audio & study 'cause its tidier,  its just more practical in my house.    But even so I would probably try to do it this way as to me it just seems the right thing to do.      

I will double check with my Linn mate on SQ,  he has a small business with 3 or 4 people in the office that runs off a multiple port HP & he used to have the audio running off that.  It was an easy set up for that as his listening/living room & office have a shared dividing wall but a while back he split it off & now has a separate Linn>Netgear>QNAP branch
