CANAAN CS6A4989, 2-channel power amplifier, Power SIP-10

This chip sounds very good and is very easy to use.
Only make sure that the gain must be high enough (not much lower than mentioned in the data sheet reference circuit).
If not it will not be stable.
The other disadvantage is that it breaks easily. It seems rather fragile. Once it has run for a while it is OK.
I have used it in four amplifiers now (with small speakers) and am very pleased with the sonic results.

I have built many amplifiers, including tube amps. This comes close to a good tube amp (with the same top-quality volume pot, etc. of course).
