Thanks for the kind words Frank. I did try the ART9 on a few mono records but I wasn't too crazy about it. I found the sound too warm and thick in the mid-range, much more so than on stereo LPs. Not sure why that would be the case.
On the second question... Yes I'd probably be happy with the ART9. However I've been kind of restless with tweaking and improving the system, so it's hard to predict whether or not I'd have the bug to try something else. I will say that the Zyx and the AT were remarkably close at times. On some studio recordings where there's not a lot of 'room effect' and not too much happening in the bass, the differences may be pretty subtle. I found this to be the case on the Rounder LP of the Boyoyo Boys (classic South African Mbaqanga music), when I listened to each side on a different cart.
