I had a Hsu VTF-2 MK3 and currently have a Martin Logan Abyss, and both were (are) great. I'm currently running a pair of Emotiva X-REF 10 and I think they're every bit the equal of the Martin Logan, and probably the Hsu. Plus, you get a 30-day return policy. Sale price tends to be $400 each, including shipping, if you're patient.
Just another option for anyone looking for a musical subwoofer.
