I've sometimes been thinking about exactly what you say here,
i.e. a rear setup creating a natural ambiace, as it happens in the
real theatre/hall due to reflections. Kindof a minimal effect, just to
add what a spaciousness-wise 'flat' stereo recording don't have.

Yes, I've tried some crappy consumer gear attempting to do that,
of cause to no avail. I'll have a look at your suggested gear.

Uhh ohh, I'm most surely going to be lectured now :-D

Not from me.

You can start with a Hafler difference-signal setup while you're looking
for
a synthesizer. (The Yamaha DSP-1 shows up all the time on eBay; just be
patient and wait for one with a remote control. If a Yamaha DSP-3000 or
JVC
XP-A1000 or XP-A1010 shows up, grab it. JVC still has remote controls,
though they're down to three.)

I should point out that the most-significant ambience is the "lateral"
sound
of the hall, not the rear reflections. All the synthesizers I mentioned
produce four channels of ambience, two of which are intended to come from
the sides.


In the 80's I worked for the classical organ centre in Oldham, they used the
Alesis digiverb units in 'dead' churches to liven up the rear speakers,
heard one once on Songs of Praise which was very weird, the organ finished
each verse with this long cathedral like decay but the choir just stopped
dead....... the Alesis is very good though.
