Choice switch audiophile network

Rate this topic

Recommended Posts

Hi all

I want to improve the audio quality of my system by adding an audiophile switch behind my streamer

Here's my installation
 

  • Lumin D1 Network Reader
  • Sbooster BOTW ECO 12 V MKII
  • Ampli HEGEL H80 - Gigawatt Power LC1 MK3
  • Pregnant COLUMN DALI Opticon 5
  • LIFATEC toslink optical cable
  • Cable HP ATLAS Hyper 2
  • Barrette Secteur GIGAWATT PF-1 MK2
  • Network link ethernet Supra Cat 8




For the etherregen,the price is out of reach at least I think for the audio set I own unless it makes a real difference compared to the other solutions proposed


I have chosen these four solutions

 



 

  • Netgear GS908 tweaked by an English: 320 euros: Lately I discovered that an English handyman proposes to tweak a basic switch: This tweak plus a linear power supply would achieve the rendering of an Aqvox SE:



 

  • SILENT ANGEL BONN N-8: 400 euros (comparative between Bonn andAqvavox SE



 

  • Fidelizer EtherStream: 400 euros



 

  • Switch Cisco SG110D-08 modified by Clones Audio: 440 euros



Which solution do you recommend me for mi. System in this budget of 400-450 -

Thank you for your answers

I can’t give you specific advice as I’ve tried none of the alternatives you mentioned, but my experience may be worthwhile. 

 

Originally I bought an AQVox SE to go in front of an Innuos Zenith SE. It brought a worthwhile improvement in sound quality that I thought was worth the money, so it stayed in place. AQVox were at pains to note that the wall wart with Shuko to UK plug adapter SMPS they supply was specifically engineered for the SE and could not be bettered even by their superior LPS. They said that certain LPSs actually made the sound worse.  OK. Anyway, the Zenith SE was producing fantastic sound that I was utterly delighted with so I thought I’d try a Linear Power Supply from Dr Sean Jacobs, the guy who designed the Zenith SEs LPSs. I duly ordered and installed a DC2, not his best but non-the-less an excellent PS.  I could not believe the level of improvement. The sound was already great but it got a whole lot better, to the point i traded back the DC2 and bought a DC3 with Mundorf caps. Wow, the jump in performance vs the DC2 was around the same as adding the DC2 in the first place....namely large.

More recently I added a new DC cable..,..built by Ghent Audio in China its made from 15AWG Neotech Ohno Continuous Cast, 7N purity cable, with top connectors and JSSG360 screens...its also 50cm instead of 100cm.  And its the cherry on the top. In summary, the careful addition of high quality power supplies and DC cable to the network switch has delivered a far greater uplift in terms of sound quality than the network switch itself delivered. The combination of switch with DC3 provides a very significant uplift in SQ, at least in my system.

Not to hijack the thread, but does anyone know of an audiophile ethernet switch with more than 8 ports? I would look at the Bonn N8 but I need at least 11 ports...

 

Is it possible to concatenate 2 Bonn N8 by sacrificing 1 port on each for the connection between them?

Try and find a used Cisco Catalyst 2960L-12 or 2960L-16. Both are fanless and offer 12 or 16 ports and will be considerably better sounding than a Netgear etc switch. I got my 2960L-16PS (PS can supply poE) for $155 used, though I think they generally run in the $2-400 range for used or open box ($1k new).

Unfortunately the details are scant on the actual testing protocols.

As always opinions will vary on a test setup, no matter how the test is performed (the same opinions don’t seem to apply on individual testing/reviewing at home..)

 

Personally I’m thankful and find it great that this test is being organised (glass more than half full!)

Just to share: this Saturday ~10 switches will be used for a double blind test.

 

Hi Fred:

Do you know if the EtherREGEN is going to be included in this test? Almost a dozen Netherlands users received one from the first batch earlier this month, so it seems possible one of them would share it for the day. B|

Thanks,

Who needs testing protocols when you're safe in the knowledge that they'll be testing switches 'playing' (assuming correct Google translation of 'speelt')? 🙂


We are far more united and have far more in common with each other than things that divide us.

Well, an obvious protocol would be in/out loop testing: Play back with the switch connected to computer/streamer and unconnected (buffered play).

I don’t know (based on the info on the website and FB), it would be great if an unit would be available.

“ On Saturday 30 November 2019 we held a switch test at Alpha Audio with ten readers. Blind ... This purely to determine whether readers can hear a difference and if there is a difference, how they are valued compared to a normal standard switch. “

 

One room, two reader groups, seven tested scenarios:

Silent Angel Bonn N8

Ansus PowerSwitch

Meraki 8-port managed

Netgear GS724T v3

Fiber converter

SOtM sNH-10G

Fidelizer EtherStream

(Unfortunately one reader -with his switch- couldn’t attend)

The preliminarily results are interesting, to say the least. More details next week.

They really should have thrown in a Cisco Catalyst 2960 as well.

+1 Blackmorec and have done almost the identical set up. The DC cables make a noticeable improvement along with the Aqvox switch. I used a Audioquest Diamond USB cable that I had laying around and made it into the dc cable.

 

Everything in the chain makes a difference.
