Default So which one is the best of the low power LM chips

So I'm planning to build a low power GC to run from +/- 16VDC. This will be a "well I already have almost all of the parts in my bin" type project.

There seems to be a concensus that the LM3875 is the best sounding of the higher power LM chips. What do people think may be the best sounding of the lower power chips?

Looking through datasheets, I can see that the LM1875 wins for lowest THD, but the LM4765 has maybe the best combination of low THD and high slew rate.

The whole problem with the world is that fools and fanatics are always so certain of themselves, and wiser people so full of doubts. Bertrand Russell

I didn't try them, but something tells me that LM1875 might be a better choice

I agree that the LM4765 may be the best of both worlds wrt slew rate and low THD. Also,

look at the S/N and damping figures. Pretty impressive!
