LM1875 distortion... any alternatives?

I was looking at the LM1875 to make an amp with about 5W max output and minimal component count. It looked fine until I saw the distortion graph.

The quoted distortion looks great with "0.015% at 1kHz and 20W". Problem is that in a living room and normal speakers, you very rarely use 20W. So if you look at the graph, then distortion is more 0.07% around 1W. Which is about 10 times more then the LM3886. And that hump is really strange compared to almost any other amp, chip or discrete.

Any better solutions? I'm looking at a minimal components amp that can do around 5W bearing in mind that in the end I might need 24 or more of them.

If you do not like lm1875, than build lm3886. Its does not matter what wattage you use it for.
 
At low levels, you must have sensitive speakers.
And for that level, you must have trained musicians' ears to make out the distortion.
In real life, does not matter.

Or look at Class D modules, quick and easy alternate, may have lower distortion than 1875.

Speakers have more distortion like in single digit percentage, so even a modest 1% will still be magnitudes larger than any chipamp's distortions. If you can get hold of genuine ICs , good PCB layout and +12/-12V PSU, you will get clean power upto 6W
