it really depends of type of amplifier , but - at quick look on data ( even if I don't have data for 7310 dynamic capacitance ) I can't see why not ...

The amp it's an arcam alpha 5, on the final stage the mosfets are died and I've to change them all.
Arcam says that "substitutes" are IRF540 or IRF 640, but I have many Irf3710 and to me (if I'm not blind) the irf 3710 looks more similar to first ones than 640 types...... |

in that case - just go for it , and let your ears decide ;
after all - that's not nuclear physics
