The LM3886 needs to be operated in a closed-loop manner, for "more predictable clipping behaviour", and most of the amplification needs to come from the high performance op-amp and not the power-amp chip. Many power-amps are designed for a minimum gain (10 for 3886) and therefore their gains need to be reduced without affecting stability.
Composite amplifier: LM3886 + LME49710 | diyAudio
https://www.diyaudio.com/community/threads/composite-amplifier-lm3886-lme49710.334273/
Hi, After reading tons of threads on this forum and all the info from the Neurochrome website I thought to give it a chance and design a composite amplifier using the LM3886 and the LME49710. I have some hobby level electronics experience and this would be my 4th serious electronics project (2...

Hi, I just build my first LM3886 composite board by my own, to learn, test, measure and all about that. I do in front of the LM and its composite OP an passive EMI "modul" with OP to filter all about e.g. 40 Khz. theoretical you see here...
DIY LM3886 Chip Amplifier (Gainclone) Kit
https://diyaudioprojects.com/Chip/LM3886_CA/LM3886_CA.htm
The LM3886 is a high-performance audio power amplifier capable of delivering 68W of continuous average power to a 4 ohm load and 38W into 8 ohm with 0.1% THD+N from 20Hz - 20kHz. For the full details and operating parameters of the LM3886 IC refer to the LM3886 Datasheet - (PDF 1.2MB). The gain of the LM3886 amplifier circuit is set about 33.

BrianGT’s Chipamp LM3886 boards. So I’ve had these BrianGT boards sitting around for along time. I finally decided to stuff ‘em and cobble together the power supply. I had to hook up stuff to see how they sound, and the answer is: fantastic. But I think I’m going to need bigger heat sinks.

LM3886 Amplifier/Speaker Wattage : diyaudio
https://www.reddit.com/r/diyaudio/comments/r50ljv/lm3886_amplifierspeaker_wattage/
I know the LM3886 can do 68W at 4Ω, but I'm pretty sure that would be to much for the speakers I'm planning on using. I wouldn't worry about amplifier wattage being "too much" for a given speaker. One does not turn up the amp to the max output. In fact, most of speaker damages out there are caused by underpowered amps turned up too loud and ...

BrianGT LM3886 based chip amp project progress. Finally wired up the chassis and sat down to listen tonight. I kept blowing the fuses in the IEC, and I figured it was either a fault I couldn’t find or just the inrush current. I quickly ran out of fuses and decided to have a little confidence in my work (I really didn’t think it was a fault ...
