Yeah,but you don't want to hear how much they charge.(smile)
I'm not obsessed with it,but the more I'm around this stuff,the more important it seems to me.
For me,and perhaps I'm fortunate to not have the ears to tell the difference,I use carpets,drapes,tapestries,and plants,untill the room is dead enough that I can't hear a sharp(percussive) handclap's echo.
I know the guys into physics will think that is primitive,and they will be right.
But it makes a difference to me,with modestly priced stuff,with expensive stuff,with all different styles of music.
