On paper the me66's might have a higher noise floor, but in practice it's never even been a remote problem. They sound great to my ears, and I've been using them for taping and videography for over 5 years now. Never noticed noise ever. Even in a completely quiet room, I doubt you'd hear anything but room noise. They go great with a V3 BTW.
Worth trying out... they retain their value well.... you could always sell if not happy.
