  1. I don't believe the new switch will be wireless. I too use a wireless bridge. But I have connected the wireless bridge to a 5 port Network switch and connect the renderer to the switch. You can so the same, just connect the wireless bridge to the input Ethernet port of the new switch and connect the 'clean' Ethernet output to the PS audio .
  2. @Superdad +1 on this. Would love to use a USPCB between my DAC and the UltraRendu.
  3. Hi John @JohnSwenson 


    Firstly, thanks for everything !

    This includes your knowledge, research, and time for the community. 


    I have a few questions:

    1) I know about grounding the negative of an SMPS but if using the Netgear GS108 switch powered with a linear PS, can / should I ground the  negative of the LPS ?


    2) How long should an Ethernet cable be? My current set up uses FMC's and a 10 meter fiber cable between then. I was thinking of removing the FMC's and just getting a 10 meter Ethernet cable between the Netgear and the renderer. 

    Is that too long? 


    3) I already have some shielded aftermarket power cords.  I was thinking of getting some copper braid and make a JSSG and put this over my existing cables, including the interconnects. Do you think this will help or not required. 


    Thanks again

      John sent me a PM.

      His was response to the questions was as follows:


      As to the questions:

      1:  to shunt leakage from upstream LAN gear you need two things: one of the specific switches, and grounding the geroundplane in the switch. The easiest way to do this is to ground the negative of the PS powering the switch, in order to be effective it must be grounded, whether it is an SMPS or linear.


      2: this is a toughy, there is no definitive answer. Ethernet is a very robust standard, there is no specific technical reason for one length over another as long as it is less than a couple hundred feet. Length may make a slight difference in sound in some systems, but other things are far more important such as keeping leakage out of a cable near the audio system.


      3: Again who knows, there are such a large number of possible variables in any real system there is no way to make a general determination on that. It might matter, it might not. it probably will not make things worse.



  4. I recently bought the SSR. I am running MinimServer on a fanless synology NAS. BubbleUPNP as the controler. I am loving the sound. Much better than my laptop running Windows Server and AO. I am using the SPDIF out to my Dac. I2S may be better but I am very happy with what I have.

    Thanks Mate.... I cannot wait. So far I have ordered and am waiting for the following: - SSR -Fanless NAS from Synology -Fiber media converter - Ethernet over Fiber - WD red drives You can imagine the anticipation. All should be here by Easter.

    That's why I ordered a 10/100 version. Still waiting for it to be delivered though.

    SSR does not have a User interface or control point of their own. You use it with apps like the BubbleUPNP and if you get the Bubble server app on your NAS, you can use almost any control app that you like including the Linn apps like Kazoo and Kinsky, Lumin app etc to control the unit. Advantage of this way of doing things is that you are not tied down to one app to control the SSR. You just just choose the app that suits you the best. Simple. On a side note I have read about a fair number of issues with the Lighting DS app.

    I was also deciding between the above but decided to get the Sonore Signature Rendu. I have not yet received the SSR so cannot comment on the sound. I believe, based on the reviews here, that it has the best implementation of SPDIF among the renderers.

    Network Isolation

    wow > wow > wow Now thats a well isolated system .. :-)

    Network Isolation

    Not wanting to open a can of worms.. at least not on this thread... but I wonder if an isolation transformer connected between the renderer and mains will help in blocking SMPS nasties coming in via the back door.

    Network Isolation

    Thanks.. God I hate SMPS's .. well atleast the cheap badly built ones supplied with NAS's and the like.... Also wanted to add I will be getting a cheap LPS for the fiber convertor connected to my computer (SSR)

    Network Isolation

    I have just ordered the non Gigabit version of the convertor. I believe just for streaming music Gigabit is not needed. Infact my current switch is also not gigabit and I have not had any issues even with streaming Hi Rez. Looking forward to trying this in my set up. The fiber will be connected between my computer (or SSR soon) and the switch which has the NAS connected to it. With the isolation that fiber provides do you think adding a linear power supply to my NAS will make a difference ?

  14. I was looking to get a NAS to replace my 4 year old Synology and came across this fanless NAS. https://www.synology.com/en-us/products/EDS14 It seems very interesting. It has no internal disk storage. It has two USB ports where you plug in HDDs or SSD's. It also has 2 network ports. I need a NAS to run Minim Server and serve Music to a rendered like the SSR and I am not looking to set up a RAID. Has anyone used this or have any opinions on this model. Obviously the main draw is that it is fanless and silent. Also it's is very flexible in regards to power requirements so upgrading to the LPS is easy if I wanted to go down that path. ATM I was thinking of getting this NAS and a couple of USB3 2.5" drives.

    Does your system sound consistent?

    I think the quality of mains power has a big affect. Evening are usually better in my place however on very hot days when many people put on their aircons, the sound quality suffers. Another big factor is what you have eaten. Unfortunately I have lost a link to the article which basically states after the heavy meal your hearing temporally suffers as a lot of the blood is used to digest what you have eaten. So to enjoy the system, have a light meal a couple of hours before the listening session. I am not sure what the article said about alcohol as I stopped reading further. If alcohol intake inhibits one ability to hear.... I don't want to know about it . And finally ............. that dreaded audiophile disease ... upgradeitis ....... My system sounds good most of the time..in fact sometimes I wonder how it can ever sound better........ But when I am looking to buy/upgrade a component everything in my system seems to be falling apart. All issues come to the fore and until I get what I want, the magic just isn't there.
