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.

Lol I was just kidding . I enjoy my 2 channel setup , I enjoy multichannel if recorded properly. But 2 channel can be better than multi channel if your front two speakers are high end , and the rest of your speakers are mid fi.

The bottom line is if you enjoy a recording , than you enjoy a recording. I have never been to a live concert where the band says OK we can only use 2 channels and Ive never been to a concert where the performers set up surround sound. In this hobby the only one you have to entertain is yourself , if you like X or Y or both X and Y
its all good.
Guess I never gave the subject much serious thought...I have the HT system in the living room for the 5.1 movies and a nice analog TT based system in a spare bedroom..seems to work for whatever listening/viewing mood I'm in...
It is not inherently better. 2 channel is a dying form of entertainment. The 'dead cat bounce' is no reason to believe that it is being resuscitated by the Cro-Magnons. I have subscribed to Hi-Fi pubications since 1965, have sold equipment in specialty stores and still buy hard/software.

The principle reason that 2channel is inferior is that it is essentially an anti-social medium. Only one person can sit in the sweet spot. Frequently you can not even move your head to maintain the illusion of dimensionality. It lives on with mostly regurgitated recordings.

If you want good two channel, buy quality earphones sit on a sub-woofer and be done with it.
