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 would agree with sean. When a two channel system is set up correctly, the soundstage needs NO speaker in the middle. The problem is that seldom do people take the time to learn and execute proper speaker placement, or people build the system without regards to the room volume and dimensions (Too big of speakers in too small of room with a rack of equipment or worse a big T.V. in the middle). This will lead to disapointment of two channel. It has taken years to get two channel right,dedicated circits, wires not crossing all over the place, dampening materials on walls,correct speaker width and distance from sweet spot, speaker in proper placement in relationship to room boundies, correct toe-in of speakers, amp stands and stereo stand dampend (which is major important with tubes). With all this done, critical listening can be done to really bring a system to life. You will hear the differance in tubes, wires and anything else you do to the system. Once you get to this point you will not want to add more because you will get less, less enjoyment! Keep it simple.
It seems that people try to improve sound by making things more complicated. I have tried this approach and have been disappointed. More speakers, bigger subwoofers, The typical american approach. Now I keep it simple and the rewards have been great

system: sony sacd-1 feeds to cary 805c with 40pt step-attenuators built-in feeding proac 2.5. two 20amp and two 15 amp dedicated circuits with kimber sockets. lots of sand and mdf board lamanted togeter for dampening. This is my path to bliss.
I should add that in many cases mono has better fidelity than stereo 2ch.
I do collect old mono records for their outstanding sound quality of the golden era.
Technically, it's not. A good multichannel system can provide far more spatial information than any 2-channel rig. The catch is the word, "good." 5.1 is a rather poor compromise essentially imposed by the movie industry. Then there are the cost and set-up challenges. I'm sticking to 2-channel (even for video!), but I won't claim it's inherently better.
The quality of imaging available in multichannel systems using height information (for example David Chesky's 6.0 audio layout) substantially surpasses what even the best of 2 or 3 channel stereo can do. Bomarc is right in stating that 5.1 is theater-driver and is not optimized for audio.
It will be some time before the recording community and audio industry at large learn how to record, produce and market multichannel audio in a practical way. This is a large subject and cannot be covered here.
However, as multichannel evolves, it's to be hoped that audiophiles will be the first to recognize the potential, since we care more about sound quality than does any other group.
Good thread. Glad to see some diverse opinions with valid points being made on both sides of the fence.

As to the stance that i ( and probably others ) took, let's just say that we have been pretty dis-illusioned with what the industry has had to offer. After all, they've handed us line after line after line of bogus advertising and propaganda regarding every "high tech" advancement that they've come up with. If this multi-channel does take off, will we have to buy a pro logic decoder ? Then what about an AC-3 decoder when that format arrives? Then what happens when DTS comes out ? I think that you get the point.

On top of that, it has "only" taken 15 - 20 years to get "redbook" cd's to sound good. While a lot of the digital knowledge that they've learned along the way can be applied to multi-channel sound, the question is will they ??? If so, to what extent and when ???

I hate to sound like a dinosaur clinging to existence as i know it, but i don't think that ANYONE wants to go through dozens of "upgrades" and "new investments" every time that they come out with a new format. Even if multi-channel SACD or DVD-A do take off, what is to say that these formats will last a reasonable amount of time ? Personally, i would put my money on DVD-A becoming a commercial success over SACD due to the multi-channel sound and video potential. I think that this is becoming more evident as commercial artists start to embrace it. While SACD may sound better ( when done properly ), quality has little to do with what the public likes or thinks is convenient.

As it is now, neither is good enough or has enough software available to make me think twice about becoming a hardcore advocate. Doing such would cause me to have to replenish my "software" collection with yet another format AND make me rethink / re-invest a large amount of time / money into making my systems "multi-channel" compatible. As such, i'm sure that i'm not alone in these thoughts or feelings.

Then again, the "commoner" with a small investment in their entertainment system might not think twice about buying the latest & greatest "full featured" multi-channel rack system from Best Buy / Circuit City for $499. To some extent, this type of division ( quality vs quantity ) pits the "audiophile" against the "average consumer". As such, we will probably end up becoming an even smaller "niche market" as things progress. After all, to the average person, "more" IS "better". Sean
