Hi, hope everyone is safe and well in today's challenging conditions.

 

I wonder if my set up would benefit from using an Edgerouter x er-x (between a virgin superhub and cisco switch), as I've seen it recommended here a few times. My chain, which is flexible and open to any suggestions, currently is:

 

Dual pc set up: Control pc (Femto net card with one port active) -> Cisco 2960CG ->1x fibre optical cable to audio pc and 1x copper cable to Virgin 2ac superhub (in default router mode). The latter is used exclusively to for wireless connection to android tablet (bubble) and has no internet connection. Music library is local storage on control pc.

 

Thanks

Hi Marcin....that's good news because I bought it  .  

 

Would you happen to know which wizard to select in the edgerouter set up page?  My femto card (one port active) has static ip set to 192.168.0.25 (for connection to audio pc and superhub via femtoserverIPaddress) and default gateway/ dns boxes are of course blank. But you need to include the latter in the set up wizard?

I think I used basic setup.

thanks.. entered the same static IP I mentioned in last post but no luck. Looks like I have some YouTube guides to study over the next few days..will get there in the end hopefully.

Hi Marcin,

 

Why you are on single PC ? is it any advantage in use dual ? what you recommend ?

 

Thanks,

I recommend single PC, but only if your server is highly optimized using linear power supplies, specialized cards, high quality sata & DC cables etc.

Marcin, does that mean that one optimized PC is better than two optimized PCs?

I'd need 2 exaclty the same configs to be able to tell for sure, but I can tell you this: with what I have here, single PC sounds so good I have zero interest to go dual PC.

Are  you trying to enter static IP of your network card as internet  connection in router cfg? If so, this is wrong. Please check with your ISP what is the proper configuration.

Thanks. Yes i was. I don't use an internet connection in my audio set up, other than tethering my mobile phone for OS updates and these days reactivating JP .

Then you have to set it as a switch.

 Would I be better off ditching the virgin router and getting something like an ubiquity access point?

Yes, I'd recommend thisi In combination with ubiquit router

I am confused. Are you (ho5456) using a cisco switch, Ubiquiti router and Virgin superhub as a router? Can you do a basic connection diagram please? I ask as I use the a cisco switch between audio and control pc. My control pc is wired into an Apple Airport Extreme router then to the Virgin Superhub running in modem only mode.

I recommend single PC, but only if your server is highly optimized using linear power supplies, specialized cards, high quality sata & DC cables etc. 

But if the server hardware is not highly optimized as described above, the dual PC route is better than the single PC route?

Hi Peter.  I am simply replacing the virgin 2ac modem/router with an ubiquity alternative; namely the ubiquity access point and er x router combo mentioned in my last post. It's still unclear whether the lack of a landline ISP connection is an impediment to achieving best results with the ubiquity gear? I only have mobile internet.

 

I use the a cisco switch between audio and control pc. My control pc is wired into an Apple Airport Extreme router then to the Virgin Superhub running in modem only mode

 

I have just the one port of my control machine's net card enabled, with a single static IP, default gateway & DNS settings left blank. 'femtoserverIPaddress' is directed to this. So just one cable (to the switch) from that PC.

 

The chain is easy to explain in words; Two PC's and one (still Virgin) router connected to the same Cisco switch. So the switch has three ethernet cables. Any set up advice/suggestions very welcome .

Marcin has, countless times over the years, said that a dual system was best for ultimate SQ, and this is also mentioned in the manual.  Has the s/w or h/w changed since then?  Well, it's still JPLAY and similar h/w, so not significantly. He did mention a while ago that a single machine was preferred for ease of testing (which Marcin obviously has to do a lot), so that may be a factor too. 

 

The single v dual viewpoint seems to change every couple of years. Over on AS, it's back to single again with the latest powerful cpu's and the likes of Euphony.  Ultimately, either should result in great SQ, as long as implemented well.

 

One important thing though with a dual system is that the network set up becomes more important, and that is why I am interested in upgrading my virgin router. Currently, I'm unable to lower my transmit and receive buffers to their minimum without stopping playback.  From a recent thread:

 

 

Not necessairly, because in dual PC mode another factor, except for the DAC Driver and PC performance, becomes critical - network latency. 

 

Regards, 

Marcin

If it sounds better to you than it is better, it certainly sounds very different, so both configurations will find enthusiasts.

I've switched to a single PC since JPLAY FEMTO as this sounds best in my system.
