content: https://englishelectric.uk/Apparently it even won an award.“The degree to which the upper end of the spectrum was cleaned up was quite a revelation, making the tone of voices and instruments far more appealing. It also opened up the soundstage really nicely, increasing its scale and depth.”Its always about the sound stage. Everything seems to open it up. Just how wide can this supposed stage get?

content: There are lots of uneducated and maybe even educated people in that scene who still live in the past, when streaming digital media was something new and difficult. They think that vinyl sounds better and this may even be based on past experience. Somehow they manage to ignore that nowadays we have near perfect digital transmission of video, even over WLAN and to mobile phones. Streaming audio is peanuts in comparison and standard equipment will do it 100 % correct. This has been true since more than 20 years. But some of those elderly are bored and a bit weak to do anything but buy things, so maybe that kind of marketing works.Regards, Dieter

content: Im loving the fact that apparently a linear power supply is no good for an audio device now:"Switches require high speed power supplies so we could not opt for a linear power source due to their speed limitations. We set about improving the power signal by using an extremely high-quality wall supply. This clean supply permits an optimum quality network signal, driven by high-accuracy TCXO clock technology."What ever a high speed power supply is .... Im surprised they would allow switching noise back into their audio stream!

content: OMG! My old 5-port GigE switch came with a classic transformer wall wart. All those years I'm using it with the wrong power supply and never experienced any issues. Must be a special audiophoolery transformer with oxygen free and cryogenically treated copper wire. And I paid only 20-something bucks for it.PS: I'm still waiting for some company to sell audiophoolery SFPs.

content: This is a nice one indeed.Whereas transmitting digital audio through SPDIF (or similar) can suffer from jitter due to transmission - and thus can sometimes benefit from improved transmission - for "streaming" audio through ethernet? Really(Oh and for SPDIF, you can do some kind of "reclocking" on the receiver side to improve jitter, which certainly is much less expensive than using moon-dust-plated cables.)(What is even funnier is the thought of people streaming lossy-compressed audio through ethernet and buying voodoo cables and voodoo switches. Of course you can stream lossless audio as well, but I'm sure among the customers of these, you'll find some that stream MP3's.)

content: I always think of carbon door handles and interior design elements for cars - they do absolutely nothing in terms of "performance", but are expensive and nice to look. Pretty much the same concept as those 2000 bucks per audio cable(But then these switches are just switches and ugly, and why reclock a CPU for a packet-based protocol?)

content: Linear supplies too slow? When a couple years ago you could buy single chip regulators that have >60dB of PSRR at least out to 1MHz, and similar load change rejection (yes I know I’m preaching to the choir, sorry couldn’t help myself). And that’s just buying an off the shelf chip. If one wanted to engineer something better, it’s no problem either, and due to the demands of deeply modulated loads as CPUs go in and out of “nap” modes at 10kHz rates, even stiffer regulators come out all the time. If anything, a switching regulator has inherent sampling and can’t really do much until the inductor current resets, so those have a hard Nyquist limit to their regulation bandwidth even if everything else was perfect. They make them multi-phase for a reason - it’s interleaved sampling just as the cheap digital scopes do to combine slow ADCs into a “fast” one (it also distributes the electrical and thermal lid across multiple devices, which is nice as well). If we were to be anal about it, a 5GHz linear PA in a WiFi router does “regulate” the output voltage at gigahertz rates 😅

content: In the past six or eight months I started purchasing older valve audio amps and receivers and rebuilding them. Just as a hobby. I enjoy working with the older technology on occasion and some sound nice.Anyway, this has led me to spend some time on various "audiophile" forums to get schematics yada yada. I've come to suspect that a lot of these people may not have much in their lives other than one upping each other or feeling a sense of superiority by dropping the name of an expensive piece of gear they purchased.I would open a thread from someone new to the hobby asking for advice on purchasing a basic item like a phono preamp with a budget of $200. The number of I saw people responding with advice like the following:"I own such and such preamp (lists one that costs $5k) you should just save your pennies nothing under $200 is good" was astonishing. It's like a certain number of "audiophiles" get off by alienating someone new to their world in a stupid display of attention whoring. Audiogon was by far the worst and I can't stomach visiting that forum. The snobbery and the one up manship is just off the charts.Anyway that's my 2¢ no one asked for.

There's no way anyone is that brainwashed(I hope). Even after being presented with evidence of it being a $30 cheap Chinese switch there's a group of about five users trying to legitimize the markup and get others that are skeptical onboard. Those have to be plants.
