Bridging a Mark Levinson 332 and 332.5

Hi there, I have a Levinson 332.5 I am currently using and have a 332 at a friends which most likely (still possible) hasn't been upgraded to a 332.5.

What my question is is how close in character are the 2? I'm pretty certain I know the answer but... Can I bridge one to each channel for 1600 watts!!! Or would I have to sell the 332 and wait for another 332.5?
