Try the Seas Excel Millenium if you can bear the thought of a less expensive reference tweeter. Most people think the more expensive product usually wins, but this is not always the case. Its virtues are see through transparency, clarity and are virtually non-fatigueing. Tweeter on the Harbeth Monitor 40 look familiar, you got it, only that one is modified by Harbeth of course. Still a heck of a bargain at about $145 each, in my opinion.
