Dougdeacon...At rows 5 to 10, the Airy 2 is the most distant sounding ? I'm not making fun of your statement, I'm just sort of amazed ! Rows 5 to 10 are pretty close to things. To echo the old cliche, "it's all relative" ; that is, to the other two cartridges. No wonder I thought you may have unintentionally erred in your earlier staement. In any event, all very interesting. I'll have to take a more serious look here. Thank you.
