content: This sounds great... by using components from audophile technology... it has achieved quantum leapsin signal quality...04:54QuoteThe sound quality of expectation cannot be judged blah blah blah.Joke: Our opinion is right... if it doesn't sound as expect to you then your hearing must be wrong.QuoteAll above reminds me a bit like of this:Quote from: Wan Huang Luo on November 13, 2018, 08:43:09 pm12.33 I see it looks like that would have fitted without cutting the fins.What if they cut the fins off to make it look like they put the crystal in there but then that isn't going to matter as they glue over the screws and not many would want to drill them out.Another audiofool company at it as well:https://dcs.community/t/upnp-disconnects/1705/33?page=2QuoteAnsuz Ethernet SwitchDlink DGS-108 REV.C6

content: Switches can make difference in Pro Audio setups. Dante for example. Lots of articles about what switches to avoid.https://usa.yamaha.com/products/contents/proaudio/docs/dante_network_design_guide/101_network_switches.htmlSome list have brand names that have inconsistent packet delay times that are to be avoided.All that said, a wrong switch and it will either drop the realtime auto streams or force you to configure for longer latency. It will sounds the same.

content: I remember another audiophool network switch. I need to check tomorrow evening if i can still find the images.It was de-branded by the sellers, but they showed an image of the board. The switch was recognizably a modded small Cisco desk switch. They replaced a couple of electrolytics, added a few in the area of the voltage regulators, and they replaced the crystal of the CPU. Just looking at the pictures the seller themselves posted, and these were quite blurry, the shoddy soldering was quite obvious.I think they sold it for more than ten times it's normal off the shelf value.

content: Quote from: Jr460 on November 02, 2022, 09:47:27 pmThere's a good reason for that and people will need to learn about Dante to understand what it is - distributed multi-channel digital audio with no world clock, so fully asynchronous, which is a pretty tough endeavor and requires strict timings and non-trivial algorithms to resynchronize/resample audio.But it has almost nothing to do with what is shown here: a simple ethernet switch for basically streaming audio from a single source to a single destination with no mixing.

content: Funny thing: They state "Made in Denmark" - which is a lie. And certainly means a legal issue (competitive regulations).Also lacking CE mark on the PSU, so it's illegal to sell in EU. Plus not matching manufacturer, so using the GS mark might be illegal as well.

content: Quote from: Haenk on November 03, 2022, 08:27:42 amAll is a lie: country of origin, mods done, improvements, EVERYTHING is a lie.The fact is that these people often get away with it.If I were D-Link I would sue them for using my brand name and packaging for something like that.Also, in addition to the scam issue, I think that whoever makes that thing is really crazy since he also took the trouble to put "special" stickers underneath the glued part.
