Un Article après test de Joel Chevassus sur les SW 6. SW 10 et le OCK-2

Le mystère des trames du réseau reste entière.
Et à réfléchir
« In the small pond of audiophile network switches, the SW-10's attractive ratio of price to build quality and features makes for a big fish. Being able to dispatch an optical transmission to a Lumin or other server or streamer equally appointed gives it a fanciful fin up over exclusive RJ45; and 10MHz clock ports open the narrow byway of home-based clock syncing.

That's a contentious topic with top digital engineers like Eelco Grimm and Ed Meitner. In Stereophile's interview with the latter, "…you don't believe in using an external word clock. Why?" "Because I think this is the stupidest thing I've ever heard in the audio business. That means you have a precision clock that you must connect to a wire to connect to a DAC when the clock should be where it belongs, inside the DAC beside the DAC chip if there is such a chip; not through a cable in a different box. This is so idiotic, it's not even funny. It's a money grab."
In Ed's view external masterclocks belong in studios where they synchronize multiple digital workstations during audio or audio/video mastering/mixing edits. They were never intended to improve a single component's performance. In Meitner's and Grimm's view, the best clock always sits within centimeters even millimeters of circuit trace from the silicon handling conversion. The clock signal does [i]not exit a chassis down an external cable through two connector junctions to be exposed to cable jitter, impedance mismatches and airborne EMI/RF. But audiophiles love cross shopping other industries and there'll always be brands to serve them. This could mean €35K for Esoteric's external atomic rubidium clock. The SW-10 welcomes less loaded shoppers with the stablemate $749 OCK-2 clock in matching livery. Equally contentious is the rationale for fancy network switches. If generic routers couldn't deliver bit-perfect data, the stock market would collapse goes the argument. The audiophile counter argument cites incoming noise on the Ethernet pipeline and more noise generated by nasty switching supplies powering generic routers. In that view an intermediate 'clearing house' becomes necessary to isolate the World Wild West from our FussyFi via optocouplers, linear power supplies and reclocking. Hello audiophile network switch. In my still short experience with the genre via my SW-8 and a competing Taiwanese switch from COS, there's something to it. Also true, I find that inserting a quality music player like Audirvana Studio to bypass MacOS's core audio engine contributes more to achieving parity between cloud and local files than an audiophile network switch does alone.[/i]
Et plus loin
Now a switch's primary function is as outlet multiplier like a generic power bar. It's why I think of network switches as LAN distributors. A single signal goes in then splits out into as many parallel feeds as we need. Just as audiophile power bars may add filter/regenerator functions or just superior parts for lower impedance and better electrical contacts, so audiophile routers may pack performance incentives beyond basic port multiplication. At least that's my view.
of my listening chair, SW-8 switch right below it. I see it each time I listen. That's no lie; nor that without it, playing local files sounds better than cloud streaming. Which isn't about dropped bits or any altered or 'improved' 1s 'n' 0s.
