Thanks! The A3X's are fairly analytical and detailed with very extended treble response and at low to medium volumes they very much enjoyable but high volumes it becomes difficult to listen to. But keep in mind they are near field monitors so they should really be enjoyed at low to medium volumes. The imaging with these speakers is highly dependant on their placement and positioning. I find the mids are actually very (emphasis on very) slightly recessed due to the emphasised treble (spoilt by the LCD-2 I guess) but overall they are very natural and effortless. With regards to bass, I find that they have a slight mid-bass hump when compared to the super tight LCD-2 bass and obviously don't go very deep (neither do most comparable monitors due to physical limitations)
I actually think the A3X have a lot in common with HE-6 which I listened to during the London meet. Their sound signature is very similar (extended treble, slightly recessed mids with the HE-6 handling deep bass better) and if I want to remind myself how the HE-6 sounded, I just turn my speakers on
Sorry to go off topic
