We Need To Talk About Ones And Zeroes

Galvanic isolation is the bare minimum, vast majority of higher end dacs and streamers have taken care of it, grounds contamination is a well known issue.

 While attending to many of these network and other streaming issues often result in incremental improvements, some may only be audible in extremely high resolution/transparent systems and streaming chains. Whatever the case, a good reference for determining the quality of one's streaming chain is to compare it to your physical media, no reason it can't compete on a level playing field with cd's or ripped cd's on local storage. Get you clocking/timing optimized and it can compete with very nice vinyl setups.

As for the Dejitter switch, I suspect this won't be the last switch attending to this issue. We can debate the theoreticals, but in the end I also rely on empirical evidence in coming to conclusions, I fully expect I will try this or another similar switch at some point.

Well said! I agree that galvanic isolation is essential and should be intrinsically baked into any serious DAC or streamer these days. Ground contamination and timing errors have a way of creeping in subtly, and you’re spot on; the higher the system’s resolution, the more these small tweaks and upstream changes can reveal themselves.

I also like your point about comparing streaming to physical media — it’s a great benchmark. If the chain is dialed in, high-quality streaming can absolutely go toe-to-toe with local files or even well-done vinyl. I’ve experienced and achieved that in my setup. 

As for Dejitter switch and any other audiophile dubbed switches, I share your curiosity. My personal experience says otherwise. After experimenting with a very high end switch (Telegartner M12 Gold switch) and few sub $1K switches, I am now of opinion, less is more.

I found audiophile switches redundant or have very minimal impact as long as we have addressed galvanic isolation between network devices, effectively breaking ground loops and blocking electrical noise from traveling through Ethernet cables.

Too often, people only consider an item’s primary purpose and judge it by how well it accomplishes that purpose, but that’s a limited, it not somewhat blinkered approach.

Indeed, by that token no one should buy a Patek Philippe because a lowly iphone keeps perfect time and the Patek sure doesn’t, so Patek Philippe must be snake oil.

Of course, accurate timekeeping has long since ceased to be the raison d’être of fine watches. Therefore their secondary purposes of beauty and craftsmanship have superceded their primary one of timekeeping.

Similarly, if a person doesn’t like to look at items of low or average quality in their home, then a well-designed network switch milled from solid aluminum and fitted with the best components and ports available makes sense. 

If the goal for that network switch is to improve sound quality, however, disappointment is bound to ensue.

The Telegärtner M12 switch doesn't use RJ-45 connectors. Instead, it is equipped with proprietary connectors, requiring the use of proprietary patch cables.

An interesting approach for sure.

He says it all boils down to galvanic isolation. More food for thought. I have no dog in this fight. 

with an forum alias of @nonoise that goes without saying.
