Tested the Merus 40 W HAT. In a first breadboard set-up, see picture.

Speakers Fountek FE85 in closed (small) box. Raspberry Pi Zero WH, power supply standard Raspberry 2.5 A.
SW, the temporary solution with the MoodeMeritAMP image from Infineon (just to test for next weeks)
AMP settings at default as shared in previous post.
Observations:
- Surprising good rich sound
- Bass performance with parametric equalizer boosted at 70 Hz for 15 dB (to correct for the FE 85 limited Bass)
- At moderate/high sound level, no audiable distortion level, also not at the bass.
- At moderate sound level, no issues with heat, AMp chip, power supply and Raspberry < 45C
All in all, for this application a decent solution. I will further detail the design of set-up and testing in the next weeks.
Keep you updated.
