I'm hoping for some improvement with the HABAmp. I hope I'm not disappointed, i.e., ₤50 disappointed.No, it comes ready assembled. It's a very basic circuit - there are only 7 components on the board in total. The amp IC, a couple of caps, an inductor and a few bits on the power traces. It uses the same amplifier IC as the one you have ordered, however that HABAmp also includes a SAW bandpass filter, so should have a significant advantage.
