There r many 5532 audio ckts on the net.
For a 7294 a 5532 is good enough. In fact it sounds really good. Phillips make sounds the best.

you may use LF353 preamp. If you want I can give you all schem.. and PCB..

That is tested and got nice result.

why do you need a preamp?
A bridged output amplifier normally has twice the gain of an unbridged amplifier. This usually results in requiring more attenuation of the input signal.
