Kimber discontinued the Black Pearl due to time consumption and production requirements that couldn't be sustained at any asking price. Ray had gifted a first-run pair to us around 1980 and later traded them for a last-run finalized version. He, of course, used our speakers in his development work.
I was honored and pleased to evaluate the finalized CS2.7 even though I was not involved in its development. I saw the careful and sustained work of Team Thiel to bring that product to market in Jim's honor.
