millercarbon, kudos on the exploration and new experiences coming your way!
Have you ever owned a quasi-line array speaker? Prepare yourself for some dramatically different (in some ways more/less pleasing) attributes. I predict it won't be as precise as your current speaker in terms of center image density and focus, but will have a great deal more presence and scale. The bass should be more profound as well. From what I heard of the bookshelf model at AXPONA (back in the days of shows; hopefully to return soon!) it will be moving in the direction of a panel speaker, with a splaying of the imaging, but a sense of openness to it - a simple trade-off based on design. (Now, for our rabid Tekton fans, I have zero interest in arguing about my observation. It's not intended as a scree against the design, but an assessment of the inherent characteristics of different designs).
It would be ideal if you can keep your current speakers and switch between them over time. It's a terrific way to play the game, by gaining familiarity with the variety of builds, designs.
You may find yourself pining for a different amp, too. A line array is a different experience with higher power.
Don't be surprised if you have mixed reaction to the speakers at first. It will be dramatically different. It takes bit to acclimatize to the new design. The scale and dynamics will probably be impressive. Go back and forth between the two (Perhaps not hourly - unless you can put them side by side! ;) ) and you will hear the characteristics of each one's design, and perhaps you will be like me, finding much to appreciate about both types. The temptation may be to quickly declare the Moab the "winner", but in time with comparison you may find that each has its own strengths.
Switching between different genres of speakers also is curious because it allows one to experience the settling effect that happens with ownership. After one adjusts to the idiosyncrasies of the new speaker, it begins to sound perfectly normal, as if it is ideal. Then, when you switch again, the settling must occur, and eventually the mind adapts and considers that also to be a distinctly "right" sound. In one sense it's a bit scary, because it shows how malleable our perceptions of what a perfect sound is. OTOH, it shows that many different speakers are capturing some wonderful aspects of performance. :)
If you have never owned a panel or quasi-line array speaker it may tickle your fancy and be "the One", the type of speaker that thrills you to no end. Looks like you're in for some fun!
