I understand that no matter how well your speakers image you can never surpass 5 or 7 channels in surround mode with 2 speakers......get real. Digital surround is discrete, not matrixed (exception being the center surround on Dolby EX). Once you downmix the Dolby Digital or DTS signal to 2 channel you loose your discrete rear channel information and its all smudged into one mono channel. I seriously doubt you can hear surround information coming from behind you in a 2 channel stereo set up.
