Guys, I can't contain myself anymore. You are evaluating FRFR speakers based on a number of elements that sequentially add unknown non-linearity into what you hear.
Scott's room -> portable Zoom recorder mic & electronics -> file compression -> your listening room -> your FRFR electronics / speaker
You certainly can compare one speaker to another in relative terms, assuming Scott's Zoom positioning was accurate, but you have no point of reference. You have no way to compensate or account for the non-linearity each link in the chain adds. Yes, I listened to the YouTube video for fun, and I could hear differences, but I would never make a purchase decision based on this. I really don't know what "neutral" sounds like in this context.
Put in other terms, this is like selecting a fine art paper to use for photographic art based on an iPhone photo that's someone has e-mailed to you.
Scott, you've put a great deal of work into this, and it has been fun. I am concerned however, that some perspective has been lost along the way.
Terry.
