Why is 2 Channel better than multi-channel?

velocity,
Thank you for your most enlightening response. Please ignore the two emails that I sent to you. I'm sorry!!! You know who you are and I now know that. Conflict sometimes bring out the best for people and I know that I have benefited from it. I know that you are a dedicated professional who has brought me up to speed. You have my respect for steadfastly defending your position on surround sound/multi channel system. You were not only defending from a standpoint of research and science, but also from years of hands on experience and of course, your passion. One has to have passion in their work to achieve the ultimate outcome. You obviously have that passion and I truly applaud you for it. I hope that all of your work will soon come to fruition in a way that surround sound will be regarded as the prime system to truly enjoy recorded music and works of many great and talented musical performers in the privacy of our homes.

Eldartford,
Well HT is multi channel, but I can understand your fondness for the center speaker. I have somewhat found its use to be problematic and effective at times and as such have used it only selectively with music. You have pointed out that a more careful selection of that speaker will yield effective results and perhaps even enhance the well talked about "sweet spot". The challenge I believe, is to be able to find that speaker quite readily. Having said that, would it be wise for enthusiasts to demand the sale of a third speaker that is exactly the same as the two being sold as a pair? That way blending is optimal and degradation of sound is minimzed or totally a non issue.

I'm not sure what you want to know. Do you want to know why a multi channel amp, with the same specs as a 2 channel, sound different when listening to a just a 2 channel amp on its own?
I've noticed that a mulit channel amp does a very poor job on 2 channel. That's why I use the 2 plus 3 amp set up.
As for music in surrond in general ( if that's your question) Is just sounds bad. My thoughts.

"Do you want to know why a multi channel amp, with the same specs as a 2 channel, sound different when listening to a just a 2 channel amp on its own?"

Yes I'd be very interested why.

"As for music in surrond in general ( if that's your question) Is just sounds bad."

The people a few posts up disagree with you, why does music in surround sound universally bad or are you just saying it sounds bad on your system?

Many recording has been optimized for 2 channel.
I have 5.1 set up with Nautilus 801 and Levison gear.
On some recording such as 1812 SACD, I do find the multi-channel provides deeper soundstage however, it is not as forward or details perhaps due to the loss of resolution on multichannel format. I heard that the two channels is 24bit/192KHz but multi channel is 24bit/96KHz.
