I had forgotten that DVD-Audio also had some options for this. It always seemed like a tremendous amount of trouble to do, even if the software supported it. The idea of installing one or two (or more) separate speakers along with switching and even additional channels of amplification just to play one or two discs was just too hard to accept. It is a little easier to accept the idea now, with PLIIz and DSX offering matrix processing to provide more widespread use of the speakers.
From all I've read, height speakers are a good idea. It's just the in-room implementation that I expect to trip up a good number of people.
Anyone else notice the supplier of the speakers under the heading "Observational Listening"? Back when they were getting good publicity such as this.
Back when they
still existed, for that matter. Of course, the speakers being discussed in that article were Swans, not AV123 products, and Swans are still available through other dealers.
