Hi,
I managed to pick up the multi-eq second hand, and think it's a great bit of kit. It especially works well if you have a difficult room set up (shape. reflections), and works across all speakers and so integrates the sub with the rest of the surround set up. I used to have the denon-avc-a1xva with integrated audyssey, but the stand alone unit offers much more tweaking of parameters and did away with the need for my velodyne sms-1 sub equaliser. It's not cheap , but it does its job very well, cheers, Tony
