See the photos in post #143, I am sitting in front of the couch these days.
At one point I had foam on top of the coffee table (when it wasn't so cluttered with accessories ) but removing it for a test makes sense. I know that when I stand versus sit there is a big difference in tonality (more bass near the floor).
I will try this and the other experiment you suggest (standing on chair listening into beam area) and report back in the next few days.
It's an awkward time right now for these types of test though; the Transparent cables are breaking in and even the Pass XP-10 (normally ultra smooth) sounds harsh.
Hmmmm....I never found the Transparent harsh when new. The terms dark, closed in, undynamic come more to mind.
