Why is 2 Channel better than multi-channel?


I hear that the music fidelity of a multi-channel AV Receiver/Integrated amp can never match the sounds produced by a 2 channel system. Can someone clearly explain why this is so?

I'm planning to upgrade my HT system to try and achieve the best of both worlds, I currently have a 3 channel amp driving my SL, SR, C and a 2 channel amp driving my L and R.
I have a Denon 3801 acting as my pre. Is there any Pre/Proc out there that can merge both worlds with out breaking my bank? Looking for recommendations on what my next logical steps should be? Thanks in advance.

I have enjoyed both but my decided preference is "you are there" mainly because I cannot fit or even imagine fitting more than a handful of musicians in my listening room. However, that is a matter of preference and the fact that multichannel media can be used to satisfy either preference should be regarded as one of its technical advantages.

I've always wanted to have a CD with a quartet recorded one per channel so it would sound like you were standing in the middle of them. I think it would sound really interesting.

I agree, Kal.
The Los Angelos Guitar Quartet has a very well recorded SACD out ("Latin"), with one of the guitar players mixed to each of the four corner channels. They have a few more SACDs out that probably does the same.

If you want to experience instruments coming at you from all four corners in quite a different genre, get the quadrophonic mix of Deep Purple's Machine Head.
I actually have a LAGQ SACD, but my player isn't multi channel and my rear speakers are comparative "junk" so at this point it's more of something that I'd like to hear rather than something that could be a reality in my system.
