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?
If you picked up some used Sound Labs, check with Sound Lab about the new backpanels. They make the speaker a lot easier to drive and also sound better too!
Hello KeithMundy
Congratulations on your purchase of the Soundlab M-1Px speakers. Your journey has just begun and you will be handsomely rewarded with one of the best bargains in high-end.

Patience goes along with owning these beasts because just when you think they are sounding great there's always a surprise awaiting you for changing cables,power cords,toe-in (either in or out),sources, or amps. Get it all dialed in correctly and because of your efforts heaven awaits at your listening chair. I wish you many years of pure joy and reliability.
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!!!!
