Nadac?

[andrew_stenhouse]

Merging has written firmware specifically for the Dell 2xxx (now discontinued) - not sure why they went this route for the audiophile market. Anyway no huge deal. I can get up and walk 3 m if I want to change the volume.

Opps hit first snag today - stuttering converting 24/172 to DSD 256. Its fine up to 24/88. Known issue with 3.12B3, apparently.

Merging has written firmware specifically for the Dell 2808 (now discontinued).

Is the Dell 2808 discontinued? It's still showing as available for purchase on the Dell web site.

Sorry meant the one before the 2808. Anyway I think Merging should package a managed switch with their firmware on it if that is what they want you to use. Or better still get rid of that idea and give you an IR remote.

I still don't understand how the mobile device is supposed to connect to the Dell switch since the switch has no Wifi. Do they say use the switch, and a wireless router together with it?

I think they presume that there is a wireless router somewhere on the network already.

Usually you will either run a switch, or wireless router. Not both. You can get managed switches with Wifi as well. Seems a bit strange. I was reading all of the online manuals, and can't find any info on setting up the mobile app. There must be a better way.

When I look at this picture, I see a Netgear router, not a Dell 8000 series switch.

Here's the solution to Andrew's problem. He needs to run a dual port FMC just like this one, right at the output his server.



Then connect one of these tiny little wireless routers up to one of the ports:



Then run the fibre to the FMC connected to the NADAC. This will put wireless onto the same LAN, so the NADAC mobile app works. But, with this dual port FMC, it's really not necessary to have the fiber NIC in the server. He could just use the 2nd copper port built into his motherboard, and return the fiber NIC. At the time I recommended the fiber NIC, I didn't realize the wireless had to be on the same LAN for the remote app.

Here's the best deal I can find. The rest of them are big bucks!

Wow....Your brain really works very fast. Do you ever sleep? It is a compliment.

Ha ha. Well I hate not finding solutions to problems. Not being able to use the mobile app with optical isolation, and dual LAN bandwidth, with the NADAC would drive me crazy.

I've actually thought of a cheaper solution that would work as well. Simply use a regular router connected to Ethernet port #2 on the motherboard, and use dual TP-Link MC220L's. One connected to the router, and one to the NADAC. That should work as well. It would be exactly like their example picture, only with optical isolation. Easier to find the parts than the other way too. You wouldn't have internet on the iPad while using it though. But will still be able to control Roon and the NADAC app.

Ethernet port # 1 will also be connected to a router, but it will just be to pipe the Internet into the server. That router will also provide an Internet Wifi connection to the house.

There may even be a way to share that Internet with Ethernet #2. But I don't know how to set that up off the top of my head. It would be nice to have Internet on the iPad at the same time.

Connecting one of the outputs on router 1 to one of the outputs on router 2, might even work to bring Internet connectivity onto that LAN.

Not so. My main modem/router in NYC apt is connected directly to my main PC and a NAS. It has WiFi and CAT5e wired to the music room where there is a switch for my streamer, a preamp/processor and disc player. I have a similar setup in CT and it seems pretty logical to me.

Connecting the NADAC to that switch in an all-gigabit network, does not work. Merging advises a managed switch but, instead, I connected the NADAC to the #2 ethernet port on the streamer with success. However, that means that the NADAC is on a different network than the NAS although the streamer is on both networks. As a result, iPad cannot see the NADAC.

OTOH, when I ran a separate CAT5e from the NADAC directly to the original main modem/router, it also worked fine and iPad access was good. Too bad that the new CAT5e is 40 feet long and runs through the dining room which makes it impractical.

Which streamer are you using that has an ethernet port to connect the NADAC to?


Yeah so if you just had a single regular router, like in Merging's NADAC diagram, it would be fine then. So should the other configuration I suggested with the 2 port fiber switch.

But I'm talking about going a couple steps further by having a separate pipeline for the internet, and the NADAC, as well as optical isolation, while still having communication with the remote app. This should be the best way possible to connect this DAC.

My NADAC app works fine, although there is a bit of lag rendering on the app (3 seconds)
My network:
FIOS ONT to ASUS RT 68 wireless router
ASUS lan out to DLINK DGS 1210-24 switch (set to defaults although it can be managed)
Everything wired plugged into DLINK including NADAC and NAS(NADAC ip fixed out side DCHP addresses as well as many other clients) Have 20 or so clients running thru ASUS.
So contrary to KR, the NADAC works fine on single network

 

[Kingsrule]

BTW I use a GISO on the copper from DLINK to the NADAC..sounds much better. I'm going to try fiber to NADAC in the next day or 2

You should try a dual LAN setup with fiber isolation like I suggested above. I don't think it can be done better. Especially if you're streaming from Tidal, and upsampling to DSD 256. You want as much free bandwidth as possible.

Makes sense, in general. I don't use the app.

No doubt. Not in my setup.

Why? Works fine right now

 

[Blizzard]

Are you resampling all PCM to DSD 256, including Tidal? The network gets pretty busy when you're doing this. Dual LAN's should deal with this nicely. Have you heard the difference optical isolation with DAC side FMC powered by ultra low noise supply makes? Since you claim other Ethernet tweaks have affected the sound, perhaps this could be the holy grail!

 

[Kingsrule]

Do you even read the posts? Like I said, I plan on trying fiber in the next few days

And I never claimed anything, just offered my experience...

I read that, but you never said a dual LAN setup, to take advantage of the extra bandwidth which is beneficial when streaming Tidal, upsampling to DSD 256, and streaming to the NADAC.


When I read something like this it sounds like a claim to me:
