My present speakers are hales t8's (hales has been out of business a long time ago) and they are about as far away from that ideal as you can get.
Wait...are you saying you think the Hales T8's are "slow" with transients or something?
I sure wouldn't say so, having heard them a few times, and having owned the slightly smaller T5s (and I still own Hales T1 speakers). I'd take the T8's over any planar speaker I've heard. But, hey, we all get the "want something different" itch.
