Failure of Multichannel


This is a supplement to the currently revived thread on SACD.  
  The most important reason for SACD, DVD-A, and Blu Ray to fail was that all physical media couldn’t survive the rise of streaming.

  There is a current attempt to revive it with non physical media, with Apple leading the way.  I don’t have any data handy but I don’t think that it’s been particularly successful.

  It was released at a time when baby boomers, the biggest consumers at the time, were raising families, perhaps having their first divorces.  It having multiple speakers, with the entailed wiring, and new sources and amplification is a more daunting start up challenge than say buying our first two channel systems as young adults.

  In the non classical/non jazz sphere a lot of multichannel releases were gimmicky, reminiscent of quad.  Separate speakers for different instruments.  This party trick could wear thin with time.Many serious listeners didn’t detect any sonic advantage, even when the mixes were more musical.  I personally enjoyed the ambiance that a label such as Pentatone would place in rears, but many Classical lovers didn’t perceive this or thought it was gimmicky.

I think you hit on something that's probably also true for Home Theater.  While chips and features have gotten cheaper, the need for more and more speakers and wires and more difficult configurations keep pushing home theater decidedly into the high-end.  This is no longer a hobby for the enthusiast/movie buff, but for those rich enough to afford a dedicated listening room. 

Interesting take. Keep in mind you can stream SACD and blu-ray or DVD-A. We don’t want to confuse the format with the medium but I get your points. Multi channel will never eclipse stereo. As of now, stereo is the king of the hill. It is established, simple and economical. This is real genius stuff. You only need 2 speakers to create a holographic image of a complex event. It uses your room and some acoustical equipment to bring you to the event. Multi-channel requires a minimum of 5 speakers and a lot of digital signal processing to do the same thing. The problem with stereo is that only one listener sitting in the primary listening position can enjoy the magic. Everyone else gets basically something closer to mono. To beat stereo you would have to do it with one speaker, most likely cylindrical (like an Alexa speaker) and be able to recreate the soundstage in two positions or even four. That’s not impossible but it would be hard.

There are speakers such as Linn 360 that go a long way towards solving the stereo listening position problem. Unfortunately, they are expensive. At least, the principle is established. Maybe, someday there’ll be more reasonably priced solutions for this issue.

I have been exposed to some of these solutions, including BACCH DSP. I don’t feel that they are solutions for this particular issue. They do remove the head-in-a-vise problem but they are far from allowing two people sitting comfortably on a love sofa to experience the stereo effect equally. Nothing is perfect, but like you said, maybe someday…
