Soundlab reliable?

Contemplating buying SoundLab M-2PX or A-3PX speakers to be driven by some Atma-Sphere amps, how reliable is the speaker? What concerns or issues have you had?
Keith what amps are you driving them with?
Also congrads you may never listen to a dynamic speaker again.
Hello Rleff, I'm driving my M-1PX panels with Pass Labs X600.8 mono blocks. Oh, I'm not giving up on drivers! In fact, I just had the pleasure to hear Magico's new S7 speakers yesterday at the Magico facility in Hayward CA. The speakers are amazing!
Yes I heard them at overture audio in Delaware and they are
amazing. I think what I like about my m2's is you can listen all day and not get tired of the session; the soundstage is just huge and being able to locate instruments within is awesome; enjoy your new investment!!!!
Just picked up some A3s that had new mylar installed in 011. I also picked up some A3 pxes along with pristine 3s and pristine 2s . Nothing can compare in my book. After hearing a good panel, driver speakers sound so slow and I can hear the xovers. They all sound like a cardboard box .

I've had a similar experience. I'm the second owner of very early A-3s (serial# A300****44.) I purchased them ~10 years ago, replaced the Mylar and they continue to sound great; better with the torrid upgrade. In the the past decade I've had no substantive performances with them.
