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.

All of the information that you need for multi-channel stereo can be captured in a two channel recording. The only advantage of multi-channel recordings is to create a spacious feeling. This can be done now artificially with surround sound processors. It's true that ten years ago surround sound processors that tried to create a live spacious feeling for stereo recordings were horrible at best. Today it's a different story. For a mere $10,000 you can buy a state of the art Lexicon surround sound processor
that will create that you-are-there feeling from two channel recordings, just as multi-channel recordings plan on doing in the future. OK, OK, $10,000 is a bit too expensive, but the price of these processors will drop in time. Remember, the price of a $10,000 plasma tv one year ago was $20,000. I'm placing my bet on surround sound processors for the future, not multi-channel recordings.

Until then, I'm very happy with my six speaker system using two channel recordings without a processor. Two stereo speakers in the center, two stereo speakers in front corners, and two stereo speakers in the rear create a wonderful three dimensional sound for me. The two pair of speakers in front provides a much more life-like image than one pair of speakers 60 degrees apart. This is a tweak that works for me.

I have developed a hybrid of the two that, in my opinion, is better than either 2 channel or multi-channel. I have a 2 channel CD going through a 4-2 multi-channel stereo system. There is no multichannel processor to screw up the sound. The 2 channel music goes through two pair of identical speaker drivers (Klipsch Heritage)positioned at the front and back of the room powered by two identical ML stereo amplifiers. A pair of TacT W410 subwoofers are positioned in the corners to povide the deep bass. Three preamps are used so each speaker is controlled individually. The preamps are connected in series so all speakers can be controlled simultaneously by the first preamp. All preamps are passive so only resistors are used to control the volume. Placette preamps are used to to provide the cleanest sound with no added distortion. The back pair of speakers are raised to a level which is hardly noticeable, but provides a three dimensional sound that is out of this world.
