That may well be, and indeed is a factor overlooked in many installations
both professional and amateur. (Still, we haven't seen any measured data or
ABX comparisons on this, so I guess we''ll have to challenge your

Oh so true, so true!
But who can believe roadies? And where's their data?

Waitaminnit! I was just told that most gear is "properly designed". Now you

And I happen to prefer vanilla ice cream.
But there's high-end ice cream out there too, with real vanilla extract, not
synthetics, although tests show that most folks can't tell the difference.
Which is why they're sold the cheap stuff. And the price makes them happy!
Likewise strawberry ice cream can have real fresh strawberries in it, or
sugared frozen juice concentrate. I can tell the difference, but then I've
had my palate educated.
I count myself lucky.
