I'd second atl4love's recommendation of that pair of Nola Boxers on ebay. I bought a pair of the originals and liked them so much I upgraded to the S1 version, sold the originals to a friend with a full McIntosh stack and now he's in love with the Boxers. They've worked beautifully for me with both tubes and solid-state. Do a search for reviews, there are quite a few online.
