vandersteen 2ce signatures

i own a pair and i am using cary cd, preamp, amp. and love the mids and highs since i listen to jazz, both traditional and fusion. they remind me of the old quads in that they don't add anything, although i believe they are a bit dry...but rather have that than extra with certain freq. hot, so in saying that...i was dissapointed because with the tubes i wasn't getting the bottom end strength that i know is needed. so i added a sub q and i like it because it does give more of the power amp to the mids and highs, but i was thinking about changing to a real good solid state amp..say bryston,etc. but scared i will loose the liquid mids and highs from the tubed amp...any suggestions? thanks
