In the 90's HP bought our lab, called it CNO ( Canadian Network Operation) part of the Computer Systems division out of Roseville,CA.
We were designing Fibre Channel Switches, One product to the market and then sold us to McData out of Broomfield Co. They laid us off all off, and then merged with Brocade, lost track after that, But the gang (ASIC/chip designers) I still see, some went to AMD(ATI),Qualcom,Broadcom so I still hear the hi-tech stories at my annual BBQ ;-)
Fosi stuff is quite OK. until its time to fix it?

No they probably design better than you do 😀
Seriously there are no perfect products and certainly not in that budget class. The usual suspects so volume potentiometers etc. Way better than the average Aliexpress stuff. I only know the V3.

Do you included yourself?
Design is usually done by a team of EE's, specialties in technology, only as good as the weakest links
Design is one thing, building a reliable and servicable product is another thing, so is using quality parts.
Lots of things to consider in a cut throat market like CONSUMER AUDIO.
I learnt a lot of about design, manufacturing at some quality minded outfits like Motorola, HP, McD. This experience is hard to come by.
These days hard to find something that will last 50+ years and be servicable throught its life.
You should see how the old EE's roll their eyes with the attitutes/smarts of the new breed of EE's, it's a laugh for me
Post the schematics if you want us to look at them and give you some pointers or BAIL on fixing it = recycle = try again on a new one.

Just teasing, you missed the smiley. Assumptions do that to me. Yes you are right, quality of modern stuff is sometimes appalling. The last years I have seen flagrant design errors in industrial gear. Easily caught and this while I am no designer. I made it a habit to find such errors and find solutions for them (if possible) just as a challenge. I even had a high availability device where the manufacturer simply forgot to program the alarm outputs and error flags. No serious condition would give any alarm. This while the series was already rolled out world wide 🙂 Common knowledge is also diminishing it seems, I have experienced serious neglect too in medical devices and their SOPs. Something I never thought to see really.
I sure hope McD is not that hamburger joint.

Those amps are so small you can put it inside the speaker box with probably the same cover plate.
Looking at those Chinese amps. I do not know how they even make a profit. Is it volume based only, are there so many customers for the products besides all their competitors. I suppose you set up the pick and place machine once and run a batch of several thousand and then assemble them at a pace the market demands.
Plus the Fosi stuff is cheap to replace if it does go wrong (vs ~£550 for a new velodyne board).
HP actually turned it into a kit for anyone interested in building it at cost. All over the world, free shipping with usual stock shipments. At that time HP had more that 200K employees. I guess it was a small company by today's standards. I think at the time Dave was the richest guy in the USA. Poor by today's standard too I guess. But I still kept my booklet the HP way and it serves me until today.
