Hiro,

I've heard the Tannoy TD-12 extensively. My friend had a pair in situ until recently. He got the Acapella Campanella to replace them. I can tell you this. The TD-12 is one heckuva speaker. Its got all the sonic fireworks, but on top of that it sounds very believable ie tone is true. Imaging is world class, and it can through a full scale image - no surprise given the dual concentric driver. Most speakers cannot deliver the scale the way these tannoys can. Also, the TD-12 has that rare quality of aliveness without generating fatigue. My friend loves the Campanella's but I think he really misses the Tannoys. I think the TD-12 truely excels with voice and also violin is to die for.
