We sell new and used equipment and we always suggest to our customers if they can find a used piece of equipment they like, to buy it instead of buying new. With used equipment you get much more for your money than buying new. Several people have suggested buying Vandersteen 2Ce Sig's and it is a good suggestion but for the same amount of money you could buy a used pair of 3A sig's. You can get much more for the same amount of money. These days with so few audio stores around more and more people find it impossible to find an audio dealer within a reasonable distance from them, many times good used equipment can found close by and at a reasonable price.
Planers are normally on our list of suggested speakers but since you found the Thiel's harsh in your room we suggest you may want to avoid planers and horns for the same reasons you did not like the Thiel's.
Here is a list of used speaker that are our best sellers. Your budget will tell you what models you can afford.
Vandersteen, Focal, Martin logan, Gallo 3.5 ( try it without the sub amp first) PSB, Sonas Faber, Legacy, and B&W.
If you are patient and are not in a hurry you can find some really good deals on used speakers. We just sold a pair of B&W 802N's in perfect condition for almost the same price as what your budget is because we did not have the original boxes and it would have not been worth the time or money to build crates and ship them so we opted to sell them locally cheap. When it comes to speakers and turntables (for us anyway) it is better to sell it locally at a lower price than to build shipping crates and boxes, pay the extra price for shipping, incur losses from shipping damage, to only come out a few percentage points ahead. If you are have cash at had and are fast making a dicision you can take advantage of these situations.
