Has Anyone Uesed A PrimaLuna Amp With Harbeth Speaker's


Hi guys, I will be on the market soon for a new amp and I keep looking at the Primaluna Amps, has anyone heard the Primaluna Dialogue Premium amp driving a pair of Harbeth's 30.1 speakers? these are 87d/b and I am not sure how this will work out?

I just honestly don't think Harbbies need tubes, they have kind of a tubey sound already built in IMO. 
I just heard the m30.1 and shl5 today powered by a Blue Circle SS integrated and the combo was fantastic. My preference would be ss or hybrid.
I'm using SS with my harbeth c7es3.   mc452 > c52.  This combination is amazing imo!
