The speaker reviewed is mine. Before that I owned the T5V and I can say that the A5X is superior. The clarity and separion of voice and instruments is significantly better and it goes a great deal louder. I'm sure there is more and cleaner power on tap.
I use the A5X with a SVS SB1000 sub crossed at 80hz so I don't miss the low end.
I cross my A5Xs over to a Rythmik F12G.
I suppose much depends on the size of the stereo triangle (the smaller the better).
Yeah, desktop with room correction. Super near field is great.
