Agreed. In addition much is dependent on the PB equipment's imaging
refinement and also control of listener placement. I'm used to placing
myself very purposefully in a hall or a studio if at all possible, but most=
cannot be expected to, and the "performance' of recordings will always be
limited thereby.

Interesting - might it not have been more discernible with directional
mics? I haven't done much with this, but accurate imaging requires careful=
phase control too, as I understand it.

Well, not particularly, just great numbers of them! They can be heard a
long way off.

What, as candle-holders?? ;-) Or did you mean Tapirs? Stereo snorts.
Well, when I bought them all there WAS was tape, so they've burned their
share, but seem to work well digitally too.

Yep, Radio Shack special orders. Recordings through the US-122 so far
haven't been particularly problematic, although to be honest I was
expecting more gain. I'm going out to the Valley tomorrow, so we'll see
what I get.
