I use netgear bridges at home (4 of them daisy chained in one room) at about 25 bucks each with their non-audiophile walwarts and they sound perfect :-)
Ethernet Clocking
i had previously reported that adding an Antelope 10m rubidium clock to the Etherregen results in major tightening of soundstage and location of individual instruments. To my great surprise adding filtering on the BNC 75 Ohms connection between clock and Etherregen results in substantial additional benefits. The filter used is a Mini-Circuits BLP-10.7-75+ DCto11MHZ model.
We are only beginning to understand how to maintain clean clocking on digital connections, it is of paramount importance to SQ.

“the devil is in the detail” I concur and that’s quite a audio system you’ve got…wow! It certainly reflects your pursuit and passion for our hobby. I’ve much simpler system compare to yours :-) |
the difference between pure digital transmission and audio lies in the analogue domain, where there is no buffering and noise from the digital domain creates havoc, The only way to detect that reliably is using your ears. To those who believe that a $2 piece of wire and a $20 switch suffice: we all believe in something… |
@lmcmalo I wish you could come round to hear my system with its ‘special switch’ and Ethernet RFI filtering. I would give you a demonstration of streaming from Qobuz with the Ethernet signal direct from the router, and then via the special switch and filtering. The difference is stunning, I do this demo a lot to friends and family, none of which have HiFi systems and are inexperienced listeners. They are all amazed by the difference, ‘night and day’ is a commonly used expression. Once you’d heard this difference you could use your valid experience of designing to help develop even greater products for us all enjoy our streamed music more. Only problem is, I’m in the UK, but if you’re passing by, please arrange to drop in. |
Her is John Quick of DCS as quotedby Austinpop on the merit of external clocks:
We began to employ external master clocks due to our experience in the pro arena, where there are generally numerous clocks running simultaneously, thereby making their use mandatory; though our engineers questioned their efficacy in relatively closed consumer systems, there is both objective/measured and subjective/listening evidence that they can have a profound effect on the sound. The theory why the dedicated, external reference makes a difference has to do with the fact crystal oscillators are electro-mechanical devices, so they are especially sensitive to their physical and electro-magnetic environment. It may be the hammer method, and you can absolutely spoil the performance of an external reference with crummy cables or improper support, but the performance gains are there to be had!
