Default Is this a good LM3886 Kit?

Has anybody done this exact one from China? How does it sound?

Any other suggestions for best possible sound? Open to any kind of chip.

Nover capacitors are not British.
I wonder how many other lies are in the description.
I also wonder whether any of the components are not fakes.

I do not recommend buying a kit from China.
PCBs is well manufactured can be reliable. But their layout design is often bad.

Thanks for your reply. What kits can you recommend regardless of the chip used?

None,
I have never seen any chipamp layout that meets an excellent layout standard.
There are two PCBs that are excellent, but because the Member has turned this Forum into an income generator, they are both very expensive. And he is not prepared to release any IP that might reduce his income flow.

Audiosector? I don't agree with the "expensive" part if they are indeed "excellent".

With such things, it's always hard to say...the seller has good ratings, but I couldn't find schematics (they might be there somewhere)...so, if you do encounter some trouble, it might be tough to trouble-shoot.

So do I need one for each channel?

Which toroidal transformer should I get if I buy two boards. Also im in Australia so we are 230v-240v.

What else can I buy other than a case? I messaged the seller to try and get a schematic.

Thanks lads!

here is a lot of members which turned into business - but what is business, I dont think they earn milions ... if somebody will, he can find a lot of things freee for diy ... if somebody will rather pay, he can do it here or ebay or somewhere ...
