Marc,
I have a pair of Super 3's, a Fi-X, and a Decware Zen triode. The 3's needed to be broken in again, and they are opening up a little, but still any opinions might be premature. But since my Abby's arrived, I've not listened to the 3's very much. After this weekend, I will get back to them, and do a more thorough comparison. The Decware has a little more power, and I'm told it likes lower impedance loads, so it might be a better match (and is a lot less expensive).
