Kappa 9 vs Martin Logan Quest Z

Mechans, What is your point? I know Bill is very good at repairing speakers. In fact he has repaired speakers for me in the past and I have purchased many speakers from him, but when it comes to listening it's just an opinion.

If you like MLs, try a vintage Infinity with EMIM midranges upgraded to the brilliant new Apogee Acoustics EMIM diaphragms. Electrostatic clarity with way more dynamic range. Here's a snapshot of my RSIIb's:

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.

Have you heard either K9's or K8's or the ML's? There's no comparison. Completely different. Almost opposites. Different amp demands. The K9's are very demanding but so are the ML's, in different ways. Different placement/ listening position. Anybody that owns either and heard the other would, at best, say a polite, "That's nice".

The question only makes me wonder if you have any idea of your own requirements. Not trying to be rude but you seem to without a plan.

I cannot say which I like better the ML or the Kappa 8. I Like the Kappa 8 over the ML Zquest and the Kappa 9s. The ML is bright and hashy and the Kappa 9 has too much going on in one cabinet. The dual woofers in the kappa 9 fight with each other. The Kappa 8 is also a difficult speaker to drive but it is kinder to amplifiers but not but not by much from the other two speakers discussed in this thread. If you want a bargain buy the Kappa 8 it blows the doors over the other two. I do not think you can go wrong with the Kappa 8. They disappear and have a great tonal balance. The friend that has my old set has changed everything in his system accept the Kappa 8 and the Threshold SA 1A monoblocks. He has tried other speakers but keeps comming back to his original choice. ML are bright as niles on chalkboard. The Kappa 9 the bass is muddy and fat confused and incoherrent.
