        You might have a good point if you'd made it back in the mid
eighties.  The fact is you can do these things digitally now with
digital filters and oversampling.  Brick-wall filters are a thing of
the past.

        I forget the context in which I mentioned them to T Owen, but
it must have had something to do with the fact I own both a Carver amp
and the Ribbon speakers in question.  Oh, and they're 6 feet tall, not
7.
