I recently bought a pair of M30's ( 30th anniversary edition) from my local Harbeth dealer. Was able to compare with the 7ES-3s but not unfortunately the HL5s which the dealer told me they no longer held as they much preferred and the 30s in comparison. Certainly for myself there was a certain magically quality I heard in the 30s which was missing from the otherwise excellent 7ES-3S . I can only guess this may be due to the different tweeter and cabinet design that the 30s have in contrast to the 7ESs and HL5s .
