I have heard some improvement on an Innous Zenith Mk II (running Roon Core) using it's dedicated ethernet port for an 818 and recently saw this on CA:

As I am still using/enjoying what is still stored on my QNAP/Sooloos server, does anyone know about this bridging option and has tried it? Sure makes a change from the anti-MQA threads...

Hmmm, the superlatives seem to outweigh any technical reasons why it could be the case.

If anything, network bridging and/or link aggrigation could degrade the quality due to:

1. Potential issue with multiple ground/earth routes
2. Adding additional points/antennas that EMI may be injected into the device
3. Incorrectly configured such that data packets are either lost or misrouted

However, if correctly configured, I cannot see any reason why it should not be any different to a single link connection. Bridging is to increase data bandwidth and potentially add resilliance - no reason why increase bandwidth is necessary as audio streaming is a fraction of even a 10Mbs connection and if you need resilliance then just fix the underlying problem.

But hey, if you think you can hear a difference, and don't mind complicating matters, then why not.

imho.

Thanks Ian,

If Meridian offered us anything regarding the possible developments for end points, let alone their ambitions (if not a road map), I would not be forced into reading about rubidium clocks for network switches eek

More seriously I have found using Roon ROCK on an NUC, or Roon Core on Innous Servers, sounds better to my ears than using Sooloos, counter-intuitive as it may seem (end points being the priority). Wondered if some of the developments elsewhere were worth trying.

And it's raining.

And as you say, it’s raining, which of course could improve the SQ for properties that use an earth rod...

Knew I should have got an earth rod...

Nic Bridging is great for Data no so for Audio, Keep it simple less to go wrong, as most bridges will use a fake nic

ie you phyical NIC0 will create a logical card called NIC0:1 on physical NIC0 this will look all good until you get a issue,
and the issues are wide ranging from i now have a single device on my network with 10 IP addresses to poor performance, Just keep it simple Qnap (Single port) to switch , then Switch to device.

Bridging only works properly if ALL your devices support it and so does your Switch and most home switches do not support bridge mode, 9000MTU or various other functions, They can be a swine to implement and fault find, I have all the commercial gear at home, and the performance gain was not measurable in real terms, switch load in creased by 50% and so did power consumption.

if you have a san with 24+ 10K spining disks in a ZFS array with 1 gig nics then brill you will see a massive increase in throughput, but in the home environment you will just have headaches
