No bass from the Clue speakers.

Since your post is very vague the only suggestion I would throw out would be most of the time a lack of bass is a placement issue. 

I should have added that I am using a bel canto evo 2i gen ii amp with a marantz sa8005 CD player and a vpi mkiii turntable. My other amp is a Cayin a50t. The lack of bass is noticeable whether I use the bel canto or the Cayin.

Is there any more information about the speakers? Also, are the woofers working? Can you feel them moving?

My recollection from the Stereophile review and the manufacturer's comment was that Atkinson noted a shelved-down bass in his measurements, the reviewer was lukewarm about the speaker and surprised by the lean bass, and the manufacturer suggested in his comments that the speaker should have been placed within a few microns of the back wall.  How close do you have the speakers to the back wall?  I think you're going to have to do a bit of experimenting with placement to get the best results.
