Power supply for ethernet switch?

There is some data to help answer the question of whether or not a quality switch can make a difference.

Some will still disagree or remain skeptical about 30 picosends of timing error being audible. So be it. But I would suggest that it’s no longer worth arguing over. It can be measured and some of us hear the improvement.

I’m aware of how the data is handled. However, I’ll just go back to what I posted:

curious. - I don’t know why the picosecond didn’t copy over from my post. Another mystery.

As to your question - I won’t venture an answer as I’m not the author of that material. The point the author was making is that a switch indeed introduces measurable jitter.  

Before this study, many believe they heard improvements from upgraded switches. I acknowledge it could still be placebo, but at least we now can begin to consider potential deleterious effects of jitter with some supporting data.

The point I was trying to make is that it’s not worth spending time on as it’s a circular argument.  A point you seem to find unsatisfying.

Despite the well-meaning intentions of those who wish to help prevent us from spending money unwisely, I recently purchased the Reiki Audio switch and upgraded power supply through Liquid Hifi. (See: reikiaudio.com) It seemed more thoughtfully designed and built than the others I considered, other than the one from Taiko.

Newly installed, it brought a sizable and unmistakable improvement over my previous switch - the English Electric.  

I don’t think expensive network switches are for everyone. They range from an expensive accessory to very expensive accessory. And I can imagine some home networks will benefit more than others, some less, based on the many variables present. Nevertheless, for me, it was an entirely reasonable and worthwhile investment.

YMMV.

I wasn’t familiar with them either until about a month ago. But a fair amount of digging and consideration for what each respective firm was doing led me in this direction. I think they’re all trying to reduce EMI noise and use improved power supplies. Reiki and Ron Buffington at Liquid HiFi - the dealer I worked with (recommended) were better able to make that case.

I’m quite pleased with the results.

Best,
