Coen,

I wish I had posted my thoughts before you ordered those diaphragms ( maybe it's not too late to get GPA to do the following ) .

Thought :
  • Whether you agree ( or realize it ) , GPAs current pricing for a 288 diaphragm is a steal . So ;
  • Offer them a $50.00 premium over the going rate ( for each diaphragm ) to test each for performance ( FR & Distortion, obviously ) / as well as matching specs to each other ( which is fairly critical for HiFi based listening, unless you are a whiz at creating passive EQ correction ) .
  • This extra $100.00 is well spent towards avoiding the head-aches ( & nastiness ) of a getting a mediocre performing diaphragm, due to some liberal QC standards.
  • This "Insurance Premium" would nicely address GPA's ( very real ) concerns about selling components to those of us who actually measure things for their expected performance traits ( & don't just readily accept the Kool-Aid of "How Great It Was In The Past" ) .



That was my main thought ( for the day ) that I wanted to share .
