I've also noticed when doing the frequency sweeps on the Avia disc that the VP150 sounds nothing like the M22s. Would I characterize it as bright or tinny? Mmm, no, not really. I'm certainly not disappointed with the VP150, but in theory (noise sweeps) and in practice (movies, SACDs, DVD-Audio) I have noticed a difference.

I tend to reqard the measurements from Avia as just a guideline. Spend a little time tweaking to your taste and I think you'll find it blends well.
