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 been into HT for a while and currently have a system that rocks with movies that are produced well. My whole set up cost me less than 7K. Certainly not audiophile class.
I recently started to listen to more music and was trying to figure out what the best solution would be ie. upgrade home theater system or a separate system for each. Here what I have learned so far.
For home theater fronts and rears are best using identical speakers. Center channel would probably work best with the same speaker again. This usually becomes a problem with regards to shielding.
If you were to set up a system like this for music as well as HT it would work fine if you use a processer with 5 channel stereo (a dsp mode).
Problem is the cost/space for extra speakers.
For audio two channel seems to be the way to go since there is very little that is produced to listen to in any other format and even less that is done well.
I just picked up a pair of Joseph Audio monitors to use for music and will probably purchase a new amp to run them. Hopefully this will make a big enough difference in quality to justify the cost of additional equipment.
So here's the end result of my research so far. Ht set up is for HT and if you want to listen to music, get the best pair of speakers and amp you can afford and stick to two channels. At least until there is something produced for multi-channel listening that's worth doing an all in one system.
Just a newbies opinion.
