I have learned a ton of tips, tricks, recommendations, and information from these forums the last few months. I just wanted to make a thread that has a nice place to read about what you have learned about today.
This one sounds trivial, but I have to check for it every time I reinstall TIDAL. Make sure you select your DAC and place it in Exclusive Mode so it can do its job without your PC getting in the way.
this is a strange one, but based on the amounts of comments i learned that the 58x is more popular than the 4xx. which is frankly slightly surprising, mostly because the 4xx have a sound signature that i feel would be really popular (altho…as someone who owns both and prefer the 58x considerably more i get it ha)
Learned that planars need proper power to function properly.
I powerd my ifi zen dac with my phone for a few weeks and when i plugged back in and it sounds better. I also started to realise that there is a sweet spot volume for my He400i 2020 where every thing will be presented properly, anything lower that that lacks alot of things and it will sounds bad.
Damn I just learned about roadie wrap from Super* Review’s live stream. Should’ve known about this sooner. I would even say this wrap is life changing lol
I learned that dolby atmos music on Tidal is enjoyable.
Thanks to @Ahobaka I learned about the existence of Harmony Design:
That’s one of the things about this hobby. There are so many little mom 'n pop type brands that you could learn a new one everyday for ???
TIL that I still haven’t learned how Ali Express works. Just paid twice for connectors I ordered 2 weeks ago. Seriously, what is the deal with their store? You order something, pay for it, then 2 weeks go by with it sitting at “Shipment accepted by airline” only for it to declare the order “unpaid”.
I know they do this thing where they don’t release the payment until the product ships, I thought I was just confirming the payment to release the order. 
Ha, cracked another one today: Hiby Music
So it’s actually Hai Bei (like “hi bay” or “hi bae” lol) = Seashell Music. And look at their logo. Of course it is. Seashell Music. 
I’m learning app development right now
I learned how to decipher vacuum tube manufacturing dates, nothing major but useful as I start my collection. 
We’re back…
I found out how to make a sceenshots with this snipping tool https://screenpixel.org/ on Windows for free. This snipping tool software uses the newest way to take a screenshot or record what’s happening on PC screen. I just need to click 2 mouse buttons. Never thught it could be so easy to do. Useful tool for every Windows users.
Was trying to find out where one of my tubes for my Schiit Vali 3 was made (in Russia somewhere) so I did the usual thing and turned to Google. Found an informative resource doc that a member made over on the diyAudio forums and found what I was looking for.
Going to share the link with the original post (downloadable & updated list in second from last post) for any interested and in the spirit of sharing information!
