Have you tried toeing in the speakers so the drivers axis cross well in front of you? That is Andrew Jones' suggestion of how the TAD's should be set up. When the focus is right the concentric drivers should present a holographic image that comes a bit forward as opposed to imaging behind the speakers, is highly focused with great inner detail, but shouldn't be "dry".
I never heard the Pioneer's but some people hear the TAD as sounding a bit "bright," and I totally understand that description.
However when I had the TAD's and used to listen to them directly after hearing un-amplified live music from up close (as opposed to from the audience) I found the speakers presented a balance very close to the real thing, which in some instances can sound forward and detailed. But I never heard any of the magnesium mid range models, just the beryllium, so I can't speak as to their tonality.
