Dolby Digital 5.1 vs. 2.0 Surround 2005-11-08 02:05:23 If I have just 2 speakers and a subwoofer, will I hear a difference with Dolby Digital 5.1 as opposed to Dolby 2.0 surround? Or will the 5.1 sound just like the surround? I am a purist, so I prefer 2.0 to 5.1 even on a 2 speaker system. But I do notice that 5.1 is louder than 2.0, which I like. As a purist, does it matter for me which type I should choose?
