There is nothing wrong with belonging to either camp but frankly, I would like to belong to both. I would like to enjoy the M80 clarity, accuracy and transparency with works that deserve such treatment but I would also like to kick back and relax with the M60 sound for pieces that are under-whelming from a recording/mastering perspective.
