I certainly agree with your list. I would add the KLH 12, which was amazingly smooth, due in part to the two acoustic suspension midranges that were run full range and equalized in the
KLH table radio and their "suitcase" all-in-one phono player. I owned the KLH 5's for many, many years--they were the same as the 12's, but in a smaller (but still large) bookshelf cabinet. I loved those, although the midbass was a little boomy in that smaller cabinet. Far superior to the 3a's.
