I spent a very educational and entertaining two hours in a rehearsal studio with MoJoKe this morning and, rather as I feared, I have been thoroughly smitten by these systems, and especially by the Audio Chain - the larger unit with the 2x10 subwoofer.
Although I have researched (quite thoroughly) all the major competitors, including all of those listed elsewhere in this thread, I cannot claim to have listened to, or played through, them all. I am therefore NOT an expert on this subject. Nor, indeed, do I have a dog in this fight. I never really got on with pooper-scoopers.
But I HAVE invested two hours in getting seriously up close and personal with this Markaudio stuff, and I have been sufficiently impressed that I'll be putting my hand in my pocket. I've already listed for sale about £2k worth of kit here on Basschat to help fund this move, and there will be more to come. I'm not here to write advertising copy for Markbass, and they wouldn't thank me for it anyway, so if you want to know more about my thinking in PA terms please drop me a PM.
But this being a forum for bass players, I should at least mention that the deciding factor for me was that this is a PA system that actually is also a serious high-end bass cab, and which can be used quite happily in stand-alone mode (i.e. no PA mixer etc.) to this purpose. Just stick an appropriate preamp or pedal in front of it, plug in to the dedicated socket and ... job done. You can do this regardless of whether or not it is in use as a PA at the time.
Rather than - as now - having three Barefaced bass cabs (610 + Compact + Midget) and two RCF PA cabs (ART 322-A) knocking about, and taking at least three of those five to every gig by my main band, I can think in terms of losing all three Barefaced cabs with no appreciable loss of performance. Having been a notorious Barefaced fanboi for roughly a decade, life post-Barefaced will probably seem strange to me at first. But I suspect that Alex won't notice that I've gone.
