Cisco Router to match Cisco WS-C2960-8TC-L

Couldn't agree more Simon,  my recent ethernet isolator tests showed the AR device caused SQ deterioration on my all ethernet system;  whereas the owner of the device we used in the tests has it on his rather more complex home audio + AV + gaming & separate office,  some parts of which are over WAP,   & he is convinced it sounds better with it.  Horses for courses I guess. 

100% for LPS,  all LPS have voltage regulation & much like the old Naim PSU's with LM317 regulators, they are noisy,  hence why Naim introduced the DR.  So what VR is used in these various LPS's, yer pays yer money & maybe you might get what you think you pay for I guess.    The forum favourite iFi iPower is a SMPS that claims to be '20% quieter' than a LPS,  they seem to work pretty good & are cheaper than even the most basic LPS,  but I guess cheap means it can't be real audiophile   ........   oh well

BTW Peder I advise against promising people WILL hear SQ improvements as there will always be those who won't ... that fact that you have and you write about it, and plenty of others have on this forum and now I understand elsewhere have also done this is enough. Those with an open mind and curious  may  then try if they haven't already.. it might not suit all of course and indeed a few have stated they don't like the SQ 'change'.. but more appear to have had a positive outcome..  the key thing as you say is have an open mind.....

Simon,of course,you have absolut right about that.I write that early....very early in the morning,I live in the northen part of Sweden and the sun goes upp quite early.

And under the summertime the sun never goes down,than you see ....... I take the chance to push a little for my part of Sweden :-) .

About the Cisco-switch,the company that we buyed  it from say that not all Ciscos goes thru the 26-point testprogram.....some Cisco's failed.So maybe it can be "a not fresch" Cisco out there in someones musicsystem if they have buy it from someone at fleabay. It can be because of that,that not everybody hear a better SQ.

I don't know.......but maybe !

But,as you........ and I say,better have an open mind ;-) .

we are a lot, in naim audio forum and other, to have experienced real improvement in adding ethernet isolators and ps as uptone or hdplex on switches.  But not so many with cisco catalyst switch.   But i will try this cisco switch, my mind sometimes is opening a little...

if i can get a cisco 2960 for around 100 dollars, with a certain guarantee, i am not so closed in my mind and open to try.

Can you give me an internet adress to buy it?   thanks

Pierre - we cant give business addresses on this forum... but online auction sites may well be good place to try

Are there not so I can send a private message to Keler Pierre.

Maybe I get up too early this morning,but I can't find it.

ok simon, i will see. For now, on ebay, i find only refurbished, and don't know if i will have a bad surprise or not after. I just want plug and play....

refurbished should be fine - these things are robust work horses. Try and ensure the the device has been set to factory reset - which clears any bespoke settings out - and will function as a regular switch with no intervention required

Having an open mind and being gullible are very close together. I could tell you that a red London bus is on the moon, and unless you see it for yourself to have an open mind. 

I have had multiple routers, its a bit of geekery on my part. from pre made ones from draytek, asus and netgear through to home builds based on dell and HP. I have used many variants of PCs for Untangle, Sophos UTM and PFSense, using ssds, normal harddrives, variants on ram, older hardware with Pentiums through to newer hardware with Core i3.

One thing I can tell you is, a router makes F all difference to a hifi sound. Open mind and all. So who is right here?

ah ok , factory reset. What is the power supply for this model, 5v or 12v? can i use my uptone audio linear ps with it?  i know you are not fan of these linear ps for switches, but for me it worked very good on my netgear gs105.  Say me just if i can try to use my uptone ps, thanks simon.

Got your mail...thanks

One thing,check the year they made it,take one as new as possible.The Company I talked about helped us with this service.Think " Naim Recapp-service " and you understand what I'm talking about .

You have the year on the backside of the Cisco.They produce it between 2007 - 2013.

I drop you a mail later......

The switches have powersupplies built into them . The 2960PD-8TT-L cam be powered by PoE or an external 48V dc 0.3 amp power supply.

ok thanks, i will look at it.    48 v is lot of, my ps can power 5v to 12v ....

i will try this cisco, i will be fixed and compare it to my netgear gs105 with teddy pardo linear ps.

I just found an article that can interest you: on computer audiophile : stability and performance from access networks. I did not really understood it, but they use also cisco 2960 switch. The hardware seems to improve the sound...

i just received the cisco 2960. After 3 hours run, i can say globally that there is an improvement in dynamics, decay and edge of instruments vs my netgear gs105/tp ps. But the sound with the netgear  /tp ps is a  little nicier, softer and less forward. Generally speaking, on most tracks, i prefer the cisco now. Perhaps, if it was possible to put a good linear ps on the cisco, this one would be better in all areas, for my ears of course. Without my optical bridge and uptone js2 to power my serve and tp link before the nds, i am not sure i would go for the cisco: i think the sound would be too bright and forward to me.  But i don't want to experiment all possibilities, with or without linear ps and cisco, with or without optical bridge....

So i decided to keep the cisco and will sell my tp ps. 

Keler Pierre,nice to hear from you again .Look earlier in this thread,I give you some advice about the installations.....input,2017 05 14,time 7,52.

I also say,let it be warm and run for a week 24/7.Our experience is that the music flow get better + other things to.

What year are your Cisco from?

You must also have some good feet under the Cisco,right feet = better SQ. I don't know what hifi-rack you have so try different feets and see what you like best.

I look forward to hear from you again.

thanks Peter, i put little granite blocks under the cisco, but the cisco is not on audiophile rack, but in a rack under tv....i have no space more and put all switches, tp link, router etc...in a tv rack separated from hifi. ( as main block, separated too).

As for cisco date, i don't know, it is not specified, i will look after.  I don't understand what you mean by imput( they are all the same , not?). The cisco was recently factory reset, the model is 2960-8tc lv 01(dg). Sold by auditmacstech, seem to be serious.  what is it time 7,52?  Does it change a lot , because i hate computers and don't want to install or configure the cisco with my pc?   

Keler Pierre....... You can also after a week or so try another powercord. I have a Chord C-Power that I don't use,so I put it in the Cisco......better in my system.

I don't say it's the best powercord for the Cisco-switch,but I have it, so I put it in. Shall later try the new Naim Powerlite.

/Peder

Keler Pierre , input = I mean the date and time I give you some installations advice earlier in this thread.I write the date and time so you can find my input easier,2017 05 14  7,52.So you shall not configure anything,promise me that .

About feets,try to cut four pieces of cork from a winecork and put between your Cisco and the granite-blocks,just to see if you can hear anything different......or maybe you can't,but try. And the router as far away from your Cisco as you can.

Just to check,the right Cisco-nr is " Cisco WS-C2960-8TC-L ", have you another number on your Cisco. You write Cisco-8TC-LV 01 (dg)

cisco WS-C2960 - 8TC LV01(DG).  The netgear was also before on the granite blocks before....The cisco is separated by 1,5 m lan cable from the router but physically very near. It must be physically far from the router?  if yes, why?   thanks

Finally, after long listening, i thought something was missing. I put the cisco at 1m from the router, on a good wood shelve. The cisco is running since 20h.

I put again my netgear / tp ps:  the sound is more natural, the voices give me more emotion, there is more silence between notes....The cisco is more forward, the dynamic is a little bit exaggerated i think.  Without my near 400 dollars tp ps on the netgear, i would perhaps choose the cisco. 

So, finally, i am sure today, i prefer my netgear/tp ps. But i understand, for strictly naim sound africionados, why they prefer the cisco.

Can you join me at my mail Peder, because i want to sell or return my cisco. thanks
