thanks for the review, jsut a question about the soundstage being forward ... does that mean there is a lack of depth to the soundstage, or just that the depth begins at the plane and not farther back?  Thanks!

Tardy reply:   The soundstage does not lack for depth but the front of it begins, as you say, at the speaker plane.

The step response (Fig. 7) looks similar to that of PSB Imagine T2. JA stated that all drivers in PSB Imagine T2 are connected in positive acoustic polarity. In Adam Column Mk3, however, "the tweeter and woofers are connected in positive acoustic polarity, the midrange driver in inverted polarity"?
