Kappa 9 vs Martin Logan Quest Z

Rrog
My point is that he has an exceptional ear for sound and has heard most speakers including I expect ML. Thus he would be a good source for any analysis and a good advisor for helping to choose the "right" speaker for Mickey44. Not that anyone other than the person listening can ever know what they really will ultimately enjoy most. A seasoned ear however I think can at least provide guidance. That was my point.
All this may be meaningless as I am uncertain if he would even want to share his thoughts on the matter.

The difference between the two would probably be best know to Bill LeGall of Miller Sound. He is truly a specialist in Infinity speakers and has worked on and improved numerous Kappa 9s. He is Wlegall on Agon just read his feedback. You may be able to send him an email for some really knowledgeable advice.
Since he is not currently selling anything here to my knowledge, there is no financial conflict of interest to disclose

In defense of my statement about Bill, he has worked on probably every major speaker marketed in this country his knowledge is comprehensive. He has been doing speaker repair and light modification with a perfectionist skill for listening as well as hand labor that few will ever match. He has been immersed in it as his only profession for in excess of 50 years. He is a personal friend who has recommended to me that given my tastes at the time to try Dunlavy and also Mourdant Short. I know he personally uses vintage Patricians and Acoustats in addition to one of the few unmolested sets of IRS V's. He once owned Arnie Nudells show off pair but sold them. I heard them and was floored.
