Surprised no one has mentioned the Ushers. I have a pair of 6381's which do a very nice disappearing act even in my compromised HT set-up and less then ideal listening room.
I've owned many speakers over the past 30 years and know of none that are a better value than the Usher 6 series (especially on the used market).
They will compete and any many cases, destroy many speakers costing "much" more. They are as transparent, if not more so, then the Maggie 1.6's I owned which were also very good in this area.
