Learned about these amp boards today. Most threads are about how cheap can they go but i want to know, how good did they get?
Which where the best finished in a box amps?
Using TDA7498L not tda7498E. "L" is for 6-8ohm speakers. Which is what is of interest to me.

TDA7498E is for 3-4ohm speakers. It’s not suitable for 8ohm. It can do more power into 3-4ohm speakers.

The TDA7498L 70w 10%THD into 8ohm matches the speakers I am getting/boxing a amp for currently 🙂, but for the 10% THD meh 🙂
