I'm not even sure what the OP is fully attempting to achieve especially since there are entire "headphone distribution systems" that can be purchased for studio use. I'm just trying to help the guy out without getting too involved in a bunch of details about it (you would need to do your own homework). While I do kind of understand somewhat what it is that he is attempting to accomplish, if it were me trying to do the same thing..... I would be taking an entirely different approach.The PAM device is class D, it should not have much dissipation.
The TDA device is class AB, and the package is only rated for 1W, so I think you would need to do your own homework there and not rely on the design being done right from the unknown super cheap vendor.
I'm outta here!!!
