Hmm, you didn't like Noble's Spartacus? Granted, it's not DD, but I felt that the dual BCDs did a pretty good job with the low end. In fact, I remember thinking to myself Joop might like this one!

I remember trying to convince @eruilluvitar that the LCD-5 (which we both have) has great bass and plenty of it. Now, granted, it took an audition on a Wells Audio Headtrip to convince him, and that amp is descended from an integrated putting out 50 wpc, but I wasn't wrong.
