Enjoyed reading your review, John. I'll comment a bit on your QS8 use. If adjusted correctly(no Panorama, center width around the middle default, Dimension to taste according to how much surround ambience is naturally present in the source material)the use of processing such as DPLII significantly improves the sense of "space" by removing surround ambience from the front channels in two-channel material and putting it into the surrounds where it belongs. The level shouldn't be so high as to be audible as a separate entity, but should instead just blend in to a rather subtle degree. However, the difference becomes obvious if the switch is made to straight stereo and the sound field collapses toward the front. I always use this for the surrounds with all two-channel sources.
