An appropriate discussion could be about how to scale the quality of the
experience from stereo to first-order ambisonics with four speakers up
to eight and more, in the same room. Installing a good surround system
is not very different from installing a good-enough stereo system. The
critical component of any reproduction system is the listening room;
starting with a dedicated room for stereo listening (with appropriate
acoustic treatments), going surround might be a big step because of the
added speakers around the listening area, but then going "up" to
horizontal ambisonics with six or eight speakers should be easy enough
if one is using a silent computer and a good software decoder (instead
of a vintage hardware decoder).
This is an important point!
Ambisonics actually does scale, which is one of the advantages. (For
example, you can reproduce 3rd horizontal order "via just 4 speakers".
And you could reproduce 3rd order on ITU 5.1, if you wish to do so.)
I mean that an Ambisonics decoder could "translate" to underspecified
speaker arrays, as long as you have at least 4 speakers. (6 speakers are
mostly better, we had this discussion years ago, speaking about
practical implementations...)
Best,
Stefan
