Buying Advice Class D amplifier board – no hiss & no “plop”

Dear community,

I am in search of a good Class D amplifier board with small measurements fulfilling the following criteria:

– 24V operating voltage
– no hissing (no high gain required)
– no “pop” sound on turning on the amplifier
– preferably mono design or stereo design (no seperate subwoofer channel etc.)
– preferably small size

I bought 4 of the TDA3116 100w mono boards (XH-M542) and was very disapponited. The board has a lot of hissing and the speakers pop when turning on the amplifier. Modications are not possible because the heatsink is glued to the TDA3116 and cannot be removed without ripping the chip off.

Thank you very much for your help.
