How can you not have multichannel system

FWIW, I'm a network television production professional. In my college days, I recorded and mixed multi track music.

I have a reasonably good understanding of recording and mixing, although I would never claim to be able to sit down at a recording desk and do it today.

Here is another sacd article where the reviewer lists her favorite 2 channel and multichannel sacds. Along the way she sheds some light, but not right on the nose. Worthwile if you want to try a few discs, even if 2 channel.

For the technical or engineer, a schematic:

realistic timbre has yet to be attained in any stereo system. isn't truth in timbre the essence of music ? isn't the sound of an instrument more important than where it comes from ?

evn if if i have frequency perception loss above 12khz, i can still recognize a tenor sax. i want a tenor not to sound like an alto. one channel is sufficient for that purpose.
