Couldn't find much info about some opamps that keep popping up in Aliexpress, so I decided to create this thread to know more about them and also understand whether they are worth testing.
There's a big family of hybrid(?) opamps easily recognizable by having a golden enclosure. The brand is called 金色乐厅 (Golden Music Hall).
You can check all family here: https://www.aliexpress.com/item/1005004049405669.html
Another brand seems to be HDAM and they claim to have some connection to Marantz's HDAM technology. There's also some different models ranging from DIP8 solid states to hybrid cans.
There's also Oracle. Not sure if they have any connection with Sonic Scientific (https://www.monoandstereo.com/2019/07/sonic-scientific-oracle-02-audiophile.html).
Finally, there are many discrete models from different stores/manufacturers. Here's some of them:
What are your thoughts about any of the them? How do they sound? Worth to try or just avoid them?
