I had a random thought this morning. There is no point in bi-amping if a person like myself uses a sub or multiples there of. All frequencies typically below 80hz are routed to your sub. Even for 2 channel, I like lots of bass and I use the sub for that duty and set my receiver to LFE+Main. So really no need for bi-amp except pure direct mode 2 channel.
