David,

I just bought a Sony TV (KV-27XBR50) that incoroporates this circuit (and is
licensed fron Hughes).  Its effect on stereo broadcasts and tapes is OK -- the
soundstage seems to get much wider.  This particular TV allows SRS to be used
on mono sources.  The effect is rather difficult to describe.  The soundstage
widens as with stereo material, but seems more "all around you".  As you move
your head from side to side, the apparent balance between left and right channels
changes drastically at certain places, much like "nodes".  All in all, SRS in mono
is rather hard to take.  It annoys me somewhat, and doesn't sound very natural.
You'd have to hear it yourself to understand.

BTW, what is the reason that Hughes would develop such a thing anyway?
