Hello! Could you connect several of these to achieve greater power per channel? If so, how would I do it?

I also have two of these ... could I use the 24 operational amplifiers as a single block?:

12W for headphone is too excessive, my dear.
12W es una bestialidad, loco, te vas a quedar sordo!

Sensitive or INsensitive? With pair of headphones of the standard quality, 1W is more than sufficient.
don't mention headphones at any time jeje
they are speakers It is an active system

STEREO HEADPHONES. 24W for a headphone is catastrophic for your ears.

Firstly you ideally need 64 NE5532 opamp stages (32 packages) to drive 8 ohms with low distortion, and you can't get 24W from it, perhaps 15W.
If you wanted to bridge you'd need to double the number of stages in each half (256 opamps, 128 packages total) in order to drive 4 ohms from each half of the bridge (8 ohms bridged looks like 4 ohms to each amp) - you'd get 60W in theory. I don't think its very practical.
The opamp array amplifier doesn't scale easily due to the power rail voltage limits.
Each half of an NE5532 can drive about 500 ohms with good fidelity, but will struggle at lower impedances. This is why 64 halves are needed to drive 8 ohms.

Of all the amplifiers I've tried, it sounds the best, with my beyma tpl150 of 100 db 0 background noise and much less aggressive and more details and barely heats up
that's why he was thinking of increasing his power ...
So I could not join two plates of 24 to achieve at least 48 per channel?

Given the supply rails set the voltage limit, the only way to increase the power is to increase the current drawn - meaning you'll need a lower load impedance. You could use an output transformer to implement a voltage step-up, effectively reducing the impedance of your existing load.
