I have only studied tube amplifiers, but I am interested in transistor amplifiers this time, and I want to study them. The problem is that I know nothing about transistors. I want to buy a kit for under $50 from AliExpress and make it as a beginner. Currently, I am looking at the TDA7293 kit and the Quad405 kit. Which one sounds sweeter? Or is there a kit that you recommend for under $50?
"Completely wrong" means completely wrong, but I mentioned "99% is fake" and not complete.
Since its opening, I have bought hundreds of kits from Aliexpress. The vast majority were made of fake and poor quality components. Almost all of the components I received from Ali were fake that did not participate.
So my determination is based on my experience.
Are you an Aliexpress seller or what?

Funny, but somehow I can't believe it! Because my experience has been exactly the opposite. The board shown above sounds much better than the TDA7293 board from Kaltec, and if you change the op-amp, it's even pretty audiophile! I've built this board into amplifiers 11 times already, and every time the quality and functionality have been very good! China is a big country, where there's a lot of junk, but just as much very good stuff. I don't believe in generalizations or prejudices against Chinese products. If it were as you claim, then Eversolo and other companies wouldn't even exist. I'm not an Ali Express seller, but a German who has been building amplifiers as a hobby for 40 years, and I don't necessarily subscribe to every prejudice because I can think for myself!
Why didn’t you give up after 50, or even 10?
Or is the idea to buy cheap kits and then simply swap out all the transistors from Mouser - and still come out ahead price-wise?

We all tried cheap Chinese/aliexpress kits at one point/in the beginning of our diyaudio journey, but we should abandon those type of projects once we get more educated.
