There is an improvement, only you can gauge if it is worth the investment. I went from M229v1)/Vp150 to M809v2)/VP150 and the upper bass the M80s play adds some added warmth the M22/sub combo doesn't play to the same extent. The M80s have a warmer less technical sound to them, yet are as equally detailed as the M22's. For me it was worth the investment.
