Cost effective dsp (+amp?)

I have a "AA-JA33286 WONDOM JAB5 4x100 Watt Class D Audio Amplifier Board W ADAU1701" on the way to me. It was $59 for the DSP + amp board and another $23 for the programming board.

I was looking for a 2.1 Class D amp and stumbled across the board on PartsExpress but it was more than I wanted to spend. One of the answers mentioned the same board being available from Sure audio and when I looked it up it was about half the price of PartsExpress so I bought one.

They have 2 channel versions and lower power 4 channel versions for cheaper. I like the idea of the programmable potentiometers/switches and that they plug into the board through headers instead of being soldered directly to the board. I am looking forwards to re-engineering my 3 piece boom box... sub with amp and controls + 2 external speakers.
