OpAmps wired in parallel

Hi,

Since we can read everywhere that wiring converters (TDA1541, 1543) in parallel, as well as Chipamps (LM series, or the TDA7293) would be of a benefit (which I confirm), I wonder what would happen if we wire 2 or more OpAmps in parallel. What would be the theoretical benefit.

I tried it with some cheapo devices (2114), so far I couldn't hear any difference towards better (difficult with those items removed from a cheap player), and they went hot, but withstood the heat a few hours, unitil I removed them.

Has anybody experienced this? Will continue if I find a multiple of some better devices.
