Sorry for the delay in responding.
Yes, I have these and am quite happy with them. I use three of them in the front with two S-85 in the rear with an MX-90 sub. I first heard M&K speakers in 1990 and always liked the balanced sound they produced.
For a two channel audio system only, I like an open sound stage with good imaging, like B&W, Martin Logan and KEF.
For multi-channel hometheater, I like the more forward sound of a horn loaded system like Klispch or some of the JBL speakers.
To my ears, the M&K speakers did a great job at both stereo and surround. I do prefer the S-125 to the dedicated 5.1 systems that M&K offered when I bought these, but I have not really auditioned their more recent product.
Because of exposure to too loud music for a long time, I suppose I have lost some of my high frequency hearing. Which might mean to someone with better hearing, the M&K might sound bright, but in the end, you have to listen a lot to find what suits you.
Speakers are like food, there is no best food for everyone, only what you like best.
