well, for what it's worth, today, I just received 2x Halogram A to go on my ASR Basis Exclusive II amp and a Halogram D to go on my Playback MPS-5. Previously I have T3 on both the amp and Playback.
So far everything sounds very promising. The bass is not yet quite as deep or big as T3 but quite a bit faster cleaner and better control. T3 could be a bit on the fat side there. The sound is more open although mid and high is still a bit hard. Well broken in T3 is darker, warmer, a bit more full body. Halogram has blacker background and more detail. I hope once the Halogram is fully broken in, I will get similar warmth and full body sound as well.
