Andrew with reponse to your last post. You should check out this show report ( see top # 1 room)
http://hometheaterreview.com/the-10-best-sounding-rooms-from-the-new-york-audiophile-show-2012/?page=2
The comments from both the room orgainiser simpfi ( who also at the time sold Harbeths) and other listeners ( via audio blogs) was that although the Harbeths plus active Gradient bass panels worked very well together.
the Active Gradient Revolutions still sounded the best.
The room orginiser has also used the M30.1s with the Gradient subwoofers but still prefers the Revolutions.
This echos with my recent experience with the Revolutions even having owning ( and loving ) both the Harbeth M40.1 and M30s for over 10 years.
As you already have experience with both Gradient (working well with your Quads )and Harbeths you really should try to listen to Jorma Salmi's enduring masterpiece . Its easily and often overlooked which is a big mistake in my opinion.
Good luck anyway.
Philip.
