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.

Please explain "Analog offers 12bits maximum resolution."

There are no bits in analog, I am confused (but it's not the first time).
Oh this is easy. Because their are so many obstacles involved in gettin the sound from your speakers to your ears. If you have only two speakers screwing it up rather than 5, 7 or even the dreadful 10 the outcome is alot less noticable to your audible perception than multichannel. there is to much going on in regards to phase, power consumption needs and room acoustics for a multichannel system. No one pays attention to acoustics in two channel system never mind a multichannel set-up. Of course this is just a general statement. There those that have paid great attention to wonderful multichannel setup. And to those i tip my hat. But, by-inlarge multichannel will always sound a lot less involving and way to destracting than most two channel systems.
look at my system I just finally posted the pics tell me what you think about my 5 channel setup.

'Tain't. Music arrives at our 2 ears from all directions. Five channels gets it lots righter than just 2.
.
The next logical step for this guy is a better AV pre/pro, perhaps with "dirrect analog bypass" for his better sources.
Try an older Krell HTS2. I think this has "throughput's" for analog pass-through...and the digital is unbeaten for DD/DTS and PCM music.
Otherwise, spend less on a more dynamic DD/DTS pre-pro, and do a 2 channel dedicated pre for your 2 channel music(looping the two together).
