$1500 bookshelf speakers with laid-back highs?

I'll throw in my vote for the ACI Sapphire XL's as well. Brilliant little speakers that melt away, and do so many things that you didn't think a small speaker could do. I read another older thread with someone saying they sounded too "hi fi". (HI-fi to me is when speaker designers try to highlight certain frequencies because they think people like it) I don't believe this to be true as they produce a very flat response aside from the very top end of the audible frequencies. This isn't a huge drop and what you give up in sizzle is more than made up for in a speaker you can listen to for hours. The highs are still there, just presented in a smooth, clear way. I've had mine for about a year now and it has been a joy every step of the way.

Dynaudio Focus 110 or 140

A used pair of Tyler Taylo's would be very hard to beat for that kind of money and what you are looking for - Ty has some used pairs, if he would replace the tweeters with the SEAS millenium used in the Linbrook for you I think you would find them fitting the bill and then some.

Used deCapos would be worth checking out.

Good luck,
