Aerial 7B's were quite like what you're describing, at least to my ears when I listened to them. I found that surprising because I had been under the impression that metal domed tweeters resulted in harshness. However, the 7B's have metal domed tweeters and were certainly NOT harsh at all to my ears. These probably could be had for around what you're looking to pay. Overall I thought that they were a VERY nice speaker when I listened to them. And of course, Aerial's a stellar company. Based on your stated sonic preferences I'd give these a strong recommendation for auditioning, if at all possible.
Addendum: I VERY STRONGLY AGREE with what Brownsfan said:
"I think you will want to listen before you buy."
Also, Like Brownsfan, I've had great prior experience with ADS speakers. Mine were 2-ways deployed in the door of our 1995 Windstar (may it rest in peace). Those had great midbass punch, were smooth and had good detail. So if you're looking to replace the ADS ONLY because you're looking for something more modern, then.....well, it's up to you but I'd certainly at least listen (preferably in your own system) before pulling the trigger on anything. Even if you're replacing them because they're starting to fall apart, I'd still listen to anything before buying it. My guess is that there's a very good chance that you're "spoiled" by what you have already.
