Picked up my new V4 M22 on walls, VP150, EP500, & QS8's today. Out of the box first impressions there is just "more" information. Midrange is slightly more articulate compared to V3's, and the top end is very different to me. The new sub seems tighter than the V3. I haven't re-ran my Anthem ARC setup, but first impressions are very good.

Debbie took the time on a Friday afternoon (with beautiful weather to boot) and gave me a detailed factory tour; it was awesome. What a professional(!) who also loves her job.
