To get the real benefit of bi-amping you need to add active crossovers and bypass the passive crossovers in your speakers. Then you'll need some measurement tools to dial in the crossover frequency, slope, etc. A lot of work but definitely worth the effort, on my Matrix 802/3s.
Bi-amping
Does bi-amping only benefit sound quality if your really driving your amp hard? I have a Mark Levinson 23.5 which is pushing my B&W 801 series 3. This amp is a beast and I never push it anywhere its max. I have an opportunity to purchase another 23.5 but don’t want to buy it just to buy it. If i’m not going to benefit in sonic performance, I wouldn’t want to do it. Any thoughts?
