I have the Proac D38 and love them. I compared it to many speakers including the B&W N804s and N803S. I have always liked the Proac sounds would not replace it with anything else.
If your budget is $5-8K then I would seriously look at the D38. They are list at $10k and rarely show up on audiogon. You should also listin to the new D28 as it is supposed to be a little better then the D25 that it replaced. I feel that the D38 is worth the difference. Very very involving and musical speaker. It makes you want to listen to music all the time! Perfect speaker for piano and classical music.
However, the D38 are not suitable for a small size room as they are full range speakers. What is your room size?
