I have my mains "bi-amped" via my Front A and zone 2 connections. Receiver has an option to set it so its supposed to be a true bi-amp. Is this a waste of time or could it possibly help a bit? I have no need for 7.1 or zone 2 so thats not an issue.

For the most part, bi-amping speakers with passive crossovers (almost every speaker made is passive) is a waste of time.

Further, bi-amping is most beneficial when you have two separate amps doing it (i.e. two separate boxes with their own transformers). In my experience, that's usually the only way you'll hear an appreciable difference in imaging and dynamics.

I guess the best way to find out whether it makes a difference to you is to try it out.
