A decent chip that TDA but the gain is fixed at 46dB, rather high for practical use at lowish listening levels - the high gain makes it rather noisy. Note the worst case is 0.5mV output noise.
Hi Guys- thanks for your suggestions I think I should stick with a manufactured board for this one. I don't have enough experience to build from scratch.
How would the LM1875 sound with my miniOnkens? Is there a parallel 1875 board anywhere. I haven't been able to find one.
It's the easiest chip to work with, best chip amp I've heard.
I'll post my layout of mine on my website if anyone is interested.
Thanks - curious why 46dB isn't enough and you need more gain from an opamp?
The input impedance is plenty high enough (above 20kohms) - I'm feeding my TDA8566 (same family as yours) direct from my DAC and its not giving any problems, rather its sounding awesome. As you're someone who appreciates the great sound of these chipamps, why not try bypassing the opamp and see if you like it better? NE5532 is a decent opamp but its not quite in the same class as the sound I'm getting from my TDA

I use an opamp as a buffer so that the previous stage doesn't get overloaded.
