Hi Chesseroo,
No, not at all. If pressed, both Ian Colquhoun and I would admit to a bias towards not treating rooms, other than our standard line of "a typical domestic mix of carpet or rugs, upholstered furniture, some window coverings, and shelving or bookcases and the like to break up excessive reflections" --in other words, a mixture of both reflective and absorbent surfaces.
Of course, there are exceptions to these general guidelines, but both of us have experienced so-called professionally "treated" rooms that were overly dead and absorbent and quite unpleasant as listening spaces.
My article was really meant to stimulate discussion about various approaches to the recording and playback environments.
Regards,
