Basically I have a 7.1 receiver that does not support True HD or DTS HD, however it does support Dolby Digital and DTS. I'm trying to decide whether to biamp or to go 7.1. I've read up on how to biamp in the manual and it seems beyond my range of knowledge (or i may just be reading the manual incorrectly). Without True HD capabilities what will 7.1 sound like? Will it basically be a modified 5.1 or will I be able to get distinct sound from every speaker? The reciever is a Denon AVR-1709 if anyone knows anything that can help me out about this.
Also I have the option for 6.1 but I won't be taking advantage of all the power this receiver has to offer. The receiver does have 6.1 surround modes though.
