Hi Pureaudio,
Not much to add to the accurate comments from Ken C and others here, except to say that the new titanium tweeter in the v3s produces a slightly more spacious and deeper soundstage than the previous tweeter of earlier models. In my listening tests, it was most noticeable in the M80 v3, the M60 v3, the M3 v3 and the M22 v3. I didn't do comparisons of the M2 v2 vs the M2 v3.
The newer tweeter along with the slightly tweaked crossover in the M60 v3 also brought smoother midrange response in the M60 v3 over the M60 v2. These changes are fairly subtle but certainly audible in a blind instantaneous A/B comparison. The smoother mids in the M60 v3s were immediately noticeable on male and female and operatic vocals plus brass instruments and reeds like sax.
Regards,
Alan
