Looking to drop in an amp3 in my Denon UD-m31 mini-system. The chip amp is miounted to the heat sink and is connected to the circuit board right next to the heat sink. There are about 20 wires connected to the circuit board so wondering if it's more than just an amp board.
The preamp must be on a chip as there is a digital volume display and no conventional motorized pot. Which is too bad as it should be pretty cheap to fix the preamp too.
The main problems with the Denon:
1) bad H/F distortion or crosstalk makes it impossible to use with metal driver speakers.
2) Lack of adequate P/S so music lacks dynamic range. You can see the stock x-former in the photo.
The other possible option is to use the "pre-amp" output rca jacks on the back. Just not much room inside to add a second amp board.
I tried to attach a photo but it is too big.
