The "politically correct" reviews say the 12.2 is more clear, extended, detailed fromwhat I remember. WhatHiFi? always bashed original M15 for it's "airless" presentation. But what did they use for amplification? The original series sounded perfect with A50i amp and CD-50 mkI IMHO. Although some people call Creek detailed and analytical compared to say, Cairn.
IMHO the newer models are bright with both Rega Maya amp and Adcom amp. I couldn't believe how unpleasant they sounded because the above mentioned setup was so darn good!!! I believe measurements of the .2 series show an emphasized top end. Some people don't want a neutral speaker with low distortion. Distortion can give our ears some "excitement" to hang on to.
