Why is 2 Channel better than multi-channel?

No. I am acknowledging that decent MCH will take up more space and cost more than decent stereo. I was also saying that prejudice was the only other reason I can see. ;-)

I guess I don't follow how MCH is better. If you compare 2 similarly priced systems and the 2CH sounds better...

So I guess my answer to the OP would be that 2CH is better because it sounds better. "At a given pricepoint" is always understood.

"At a pricepoint" is not universally understood. If you want (it) to be understood, you must say so.

In addition, even at a pricepoint, the choice might be influenced by the particular pricepoint. For a $2K system, I would certainly agree that a 2CH system would sound and, therefore, be better. For a $200K system, the situation is debatable. The advantages of MCH will, imho, will be more enjoyable compared to a $100K 2CH system and, also, more enjoyable than any incremental improvements you might make to the 2CH system for an additional $100K.

Is that a real-world analogy? For some, it is. OTOH, we are speaking of generalities here.

There is no reason why you can't enjoy both. It does take a substantial investment into multichannel to have a system that does both very well.

I have been struggling with this myself and have decided after listening to a limited number of SACD recordings that I am going to convert back to 2 channel and utilize my 5 channel amp to bi-amp my Linn Ninka's and call it a day. Most films I watch are just fine in 2 channel anyway

I'm a little late to the game here but could not resists weighing in. There is no doubt in my mind that a very good recording which is available in a 5.1 and 2.0 mix, is more enjoyable in 5.1 at any systems pricepoint over say 5K (or even a bit lower). For example, the Nordic 2L recordings come in 5.1 96/24 and 2.0 192/24 and the MCH mix wins hands down on any half decent surround system.

Think of it like this. You have say 20K invested in a good 2 channels system, and have 10K more to spend. Your options are upgrading your 20K 2 channels system to a 30K 2 channels system, or spend 10K on a center channel, pair of surrounds, 3 channel poweramp and active sub. Your 2.0 channel upgrade is deep into diminishing returns territory, while your 2.0 to 5.1 upgrade is a huge net system improvement. The issue is that because outside of the classical reportoire there are so few good native 5.1 mixed recordings available, many people in the audio crowd would understandable opt for the 2 channel upgrade anyway. However, this is not because a 2 channel 30K system is better than a 30K 2 channel system. It is because there is no content to enjoy the superior 5.1 system. Obviously for the movie crowd the equation is different.

So in my opinion you cannot discuss the relative merits of 2.0 and 5.1 without considering availability of content. Interestingly, the way audio is evolving it looks like legacy MCH high rez (i.e. SACD and DVD-A) is dead, future MCH high rez (i.e. Blu Ray music) is not really going anywhere, and 2 channel high rez may well have a future through 96/24 and 192/24 downloads. I personally love MCH high rez audio and this state of affairs frustrates me no end, but what can you do other than spinning your favorite MCH recordings over and over again....
