Default Chip amps amplifier ranking


How would you rate chip amps amplifiers you built in past?

Maybe this information will help others decide which amps to build.

6 power amps with 2xTDA7293 rebuilt to be transconductance amps by making the feedback loop a current feedback.
Adding external DC servo, and adding some voltage feedback at high frequencies to prevent oscillation.
In practical use you end up in rather low distortion, since you are decreasing the distortion from the speaker. Quite impressive!
Inspiration from this tread:
