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.

Wrong on many counts...A guy only needs 2 stereo pairs (total of 4) and it can all be done analog without any dsp.

The following describes a setup with 3 pairs, but, one can get some great results with just 2 pairs... that can make him regret going back to stereo.

Angela Yeung has many videos on this topic.

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.

That may well be true. Nevertheless, I’d rather spend my money on improving the sound quality of the two channels I have than on acquiring more. Each to their own.

You could crack out the stereo as much as you want....But, there’s a very finite limit above which there is no perceivable upgrade, only side-grades, different sonic signatures, repackaged and sold over and over in a different chassis, different color lights and buttons from different guys. It’s a fallacy that an endless amount of sonic upgrades shall be bestowed upon a guy just because he keeps paying up. Such a thing shall never happen.

 

What Angela Yeung’s describing is actually a very simple and straightforward experiment...no dsp, no complicated prepro with a steep learning curve, no 360 reality, no neural x, no atmos, no auro 3d.......nothing but good ol’ analog stereo, continuing to keep it simple for simple minds, no one’s trying to teach old dogs any new tricks.  She’s just talking about adding another stereo pair of speakers sitting behind the listener receiving the same stereo signal that the front speakers got....

 

Most guys around here have an extra set of preouts on a preamp that’s hooked up to their turntable, i’d assume??

Most guys around here would have an extra set of bookshelf speakers and a poweramp or something catching dust in storage??

Well, put the bookshelf pair straight behind the listening position and hook it up.  Flip the phase on them (swap the left/right speaker cables) or not and see what works best. You may need something like a 40 dollar Schiit Sys for a separate level adjustment on the back speaker pair to move the resultant stage depth forward & back, based on what works in the room, that’s it....It’s not surround, it’s not quad....it’s good ol’ stereo and it’s really not complicated.

 

That may well be true. Nevertheless, I’d rather spend my money on improving the sound quality of the two channels I have than on acquiring more. Each to their own.

Ah! That old chestnut, diminishing returns. Of course, it’s quite possible to spend unwisely. That doesn’t mean it can’t be successful as well.

Stereo has nothing to do with how many speakers you use. It refers to how many audio channels are in the recording. Whether you use 2 pairs, three pairs or 4 it’s still stereo. By the way, what you’re advertising is not new. People have been doing it for decades. .
