Okay… we did some experiements with this before. But with the new RF Shielding box the measurements are much more stable. So, time for a follow up on clocks in Network switches!
There are a lot of switches out there. Consumer grade, professional ones and since a few years: audiophile grade switches. Some of them have better power supplies, some even have special ‘audio grade’ clocks. Or external inputs for reference clocks.
We always try to figure out what the effect is by listening to new gear ánd try to measure the influence. With switches it is really hard, for there is no ‘audio’ going in or out. At least: not a signal we can capture. So, in order to get some usefull insight, we try the next best thing: measure in the streamer that is connected to the switch!
That sounds easy, but it isn’t. We noticed that – if you want to have stable results – you really need a stable environment. Especially if you dig in to the picoseconds or even femtoseconds, like with the Wavecrest SIA3000 analyzer. That’s why we build the RF shielding box… the results are pretty interesting!
