The best speakers you can buy for under $2000 are IMO, the PSB Image T6 speakers. They are around $1400 per pair.

Both Stereophile and The Absolute Sound have tested them and rated them the best in their price range.

I had them for two years and they were very good in every respect. I only sold them when I moved on to the Vandersteen Treo speakers ($6000).

They have good sensitivity and your amplifier should be adequate for them for all but the very highest volumes, which you apparently won't be doing.

You should read the review article Stereophile did on them; available right here on this website.

Highly recommended.
