I guess I am a bit confused. You mention that you want to upgrade, but then ask for an equivalent speaker recommendation.
This way I can use the next model up as my starting point. For example, if the M22 is equivalent, then I should start my research with the M50.
Even though the Mirage M-490 is officially classified as a bookshelf, it is quite a bit larger than the M22 v2 (1,985 cubic inches vs 1,156), and has an 8" woofer. At the time I bought it 10 years ago it was considered a very good speaker. I want to make sure that if I upgrade, I will hear a noticeable improvement.
Thanks everyone for your suggestions so far.
