I have a pair of Thiel CS 3.6 speakers good to about 27Hz/2db. They are great speakers. Even though mine are a part of a 7.1 system, I listen to a lot of 2 channel stereo using just the Thiels. This is a discontinued model but can be found for less than $2000 a pair used in great shape. I found mine for about $1300. Got lucky.

A pair of Axiom M80s might do ya.

Enjoy the Music. Trust your ears. Laugh at Folks Who Claim to Know it All.
