Relationship between Ethernet Switch and SQ

... This isn’t fast enough for streaming so error checking goes out the window, replaced by "error correction" meaning that if a bit is dropped, some value between the 2 adjoining bits is chosen (interpolation) ... So streamers, clocks, power supplies, and audiophile switches are ways we endeavor to avoid dropped bits ...

What streaming service are you using? I can tell you that Qobuz uses the TCP/IP protocol, so the end user should get a bit-perfect transfer. It takes very little network speed for Qobuz to work and even at hi-res, 10 mbps should be enough. Remember that your streamer will load content from a service such as Qobuz into a cache, so if there is an error in transmission, there’s more than enough time for the packet to be resent. Interpolation isn’t part of the protocol - at least not for Qobuz over TCP/IP.

Let’s not confuse caching with buffering…I’m asking about caching.

If you want to be precise, what a streamer really does is load the file into a buffer. It’s really a difference without a distinction, though. You’re getting a bit perfect file from a source such as Qobuz because the data is sent in packets over TCP/IP with error correction and no interpolation, contrary to your claim.

You haven’t identified your streaming source and I suppose it’s possible that you’re not getting bit perfect files from your provider. Which service are you using?

Cheaper streamers buffer. Higher end streamers cache. Some higher end streamers buffer but use a healthy buffer area and processing to ensure the data is clean.

What streamer are you using, @audphile1 ? What streaming service are you using that "isn’t fast enough for streaming so error checking goes out the window, replaced by ’error correction’ meaning that if a bit is dropped, some value between the 2 adjoining bits is chosen (interpolation) "?

You can fiddle with power supplies on your streamer all you want, but you’re likely to get much greater improvement by looking at your streaming service and cleaning up whatever network problems are contributing to your dropped bits.

Meanwhile, I think @mathiasmingus made a great choice in the Bryston BDP-3. I dumped an Aurender for the Bryston and have never been happier. Yes, the interface is crude and some people just can't get passed that. But it's a terrific streamer.

I am using a network renderer in my DAC (Bricasti M3) as a Roon endpoint (Roon core duties are handled by Mac Mini) without an outboard dedicated streamer. I also occasionally use MConnect to bypass Roon and stream direct from streaming services (Qobuz and Tidal).

It seems to me that something is badly amiss if you suffer dropped bits while using that equipment with Qobuz, as you describe below, @audphile1. I'm not a Roon user, so I don't know if maybe that's where your problem is. But you should be getting bit-perfect delivery from Qobuz and if you're not, you be better served by fixing your network issues than anything else. If all of your wiring and connections are tight and secure, you might want to look at that DAC as the culprit.

... I get why people want to be in the cult of anti facts ...

Of course. That's your world.

I am an expert, however, you fall under the Dunning Kruger effect ... I called him a BSer. Because that is the truth ... he is just another clueless guy hawking gear that doesn't do anything, at best, at worst deliberately trying to make money of people who don't know better. 

Nasty insults are no substitute for reason. They actually weaken whatever argument it is that you might be trying to make.

... how about an actual test and dissecting of an "audiophile" switch?

People have reported their results but you tend to dismiss them with a wave of the hand or a string of insults. Of course you could conduct your own test, couldn’t you?

But when you don’t know anything about the topic, it is easy to be caught up details that really do not matter.
