Thanks very much for the careful (and positive) review Tom. The one issue that jumps out is your observation about the possibly restricted width of the soundstage on both the HT2 TL and the Song Tower. The only explanation I can think of would be the MTM configuration they share. If you had only noticed a narrower soundstage on the the HT2, I would have concluded that it was related to the LCY ribbon, which has a wider element than some other ribbons, and therefore might have more restricted horizontal dispersion (but superior vertical dispersion due to his shorter height). But the little 0W2 some tweeter used in the ST has about the best dispersion out there, so it can't be a question of tweeter dispersion. It also can't be the crossover slopes, because the 4th order Linkwitz Riley acoustic slopes I chose are widely used by other manufacturers. That leaves the MTM design, which was originally developed to optimize vertical lobing, and not for any particular performance in the horizontal domain. But the soundstaging characteristics of MTM's aren't all that well understood, and the driver placement may in fact affect soundstage width. There seems to be a compensating advantage in imaging, so I guess this is just another one of those trade-offs so prevalent in audio.
