I had a couple of pairs of DM3s I got direct from England about 1970. They were good speakers, I sold them when the Spendor BC-1 came out. I had had a pair of P2Hs, which was their first speaker, then a pair of DM-70s, which a friend of mine still has. They were both hybrid speakers , the first with an Ionic tweeter, the second with electrostatic. The DM series were good speakers for their time but not up to some later ones.
