I do. I didn’t tried them, but I did a comparison.
Hifiberry Amp2 (65,64€ Amazon):
Justboom Amp HAT (69,6€ Amazon):
Basically they are the same. Both using the same Texas Instruments Chip (TAS5756M) . So the specs are identically (2x30W) so I think electronics around the chip are probably also the same.
And cost almost the same 🙈 the Justboom has more features. Like Softmute, Hardware mute, IR control, etc. etc. etc. eeeetc.
The JB HAT has spaces for the camera cable and display cable. None of the hifiberry have them. So big minus for the hifiberrys. And pins for the Rpidisplay (what ever).
The speakers aren’t so small (https://www.neuhold-elektronik.at/catshop/product_info.php?cPath=242_253&products_id=6537) but they are quite flat.
And flat speakers are what I’m looking for. They are designed for TVs so they are quite good for higher Hz (voice and music) but due the small cones, the don’t have much Bass (Deep Hz lower than 110Hz are missing) and so you will hear that (I play with the idea to add an crossover with a pair of exciters for the bass, said in an other thread here).
One speaker 10W RMS/20W peak @4Ohm. I’m using two per side, so ~20W RMS @8Ohm left and right. It’s not perfect but with the exciters I think it will be almost perfect for me.
Next step, add the Flick HAT to control the volume :
I don’t know if the flick works with the hifiberry amp2 also (I do not really care cause I have the JB)
Pictures, yeah sure! I will post more till the end of the project :) next steps will be the flick and the frame, … the LEDs (indirect RGBs around the mirror) direct above (1m CW/WW Led strip like this: https://www.lampenwelt.at/100-cm-breite-led-spiegellampe-esther.html? ) and so on… and on and on ^^
