Really? I have Salk HT3s (older model) and have not noticed a "non-coherent sound of separate drivers". I can only speak to the HT3s, though.
I always liked Dynaudio, too, and they were the top speaker when my friend and I did a shootout of many different speakers in around the 4-8k price range. For instance, for me, the two Dynaudio we listened to were much, much better than B&W, which made my ears hurt.
I also like other speakers, too. I still like my Linn 5140s and loved my VMPS RM40s (though my wife did not like the coffin look). Of all the speakers, to me, the RM40s were the best in their price range and the best I've owned.
I agree. We have auditioned 4 different Salk models (SoundScape12 [wow], HT2, SongTower, and Ellis 1801). One of the positive joys of all of them was the driver coherency from top to bottom...from twinkling, airy cymbals to powerful bass lines. If fact, I would call coherency a trademark of Salk loudspeakers.
