I run Horning Eufrodite Ellipse with my FW SIT-3 and the pairing is excellent. I also use my Frankenstein Mk.2 300b's mono's and like them a little better, but I like tubes and the SIT-3 is a beautiful sounding SS amp.
If the Eufrodites are too big or not in your budget the Aristotle would be a good match.
