Speakers under $3-4,000?

My few cents worth based on your stated amplifier and budget:

Gemme Audio Katana's are great and will fall in the middle of your budget ($13,000 when new for the V2s). I have a pair of these and also a pair of Wilson Watt/Puppy 5s and after 6 months still can't determine which is a better speaker for my tastes and which ones to keep/sell.
The Thiel 2.4's were a good rec., but why not also consider the 2.2's which sound very, very similar and can be had for about $500 (a cheap way to determine if you like Thiels).
Dynaudios are another good recommendation.

I have a lot of respect for Elizabeth, but I am not so sure about the Mags unless you have already listened to them and know you like their sound. I know E will probably dispute this, but I think they are a higher maintenance speaker when buying older used ones than MOST people want to deal with. If you are going Mags, I would find a dealer and consider buying new or at least a later mfg. pair locally (which she suggests anyway).

Ckoffend makes good points. I did not recommend the Thiel 2.2 because I have not heard them. There are just so many good buys out there on the used market. You can get the Revel Studio for around $4500 ($12000ish when they came out) and make your first highend buy your last (assuming it is your first)...

There are rebuilt Quad 57s, Quads 63s, or a good used pair of Quad 988s !!!!!!!!!!!!

Try some NEW BOSE series 6 version 2's....one of the BEST and future CLASSIC that we will talk about for a long time! These new 901's have had over 650 improvements done to them! They don't even use the same speaker drivers as was in the 1988's 901 series 6 any more! Two pair of these NEW 901's STACKED sound DAMN GOOD!....
