A friend of mine is using the Quad 11L with great success. Another one I would highly recommend that I liked even better on his Classik are the Spendor S3/5. Also, I liked the Spendors more than the Tukans. The Spendors were the best combination I heard to date with the Classik with lost of detail, smooth highs, fast and lively. And they can be had close to $600 used.
Good luck,
Rene
