With the Classik, I would want something efficient and sweet in the midrange.
My Dad uses Triangle Titus ESs with his Classik. They are efficient enough to be used even in a fairly large room. He's very happy with the sound. The ES model might be a bit closer to $550 than $500 on the used market.
B&W 601s should work fine but when I listened I thought they were a good deal less lively and involving than the Tituses. Less efficient too. I actually preferred B&W 302s.
