Yes, I do have Blue Circle / B&W Combination and I do enjoy it very much. The Soundstage reviewer of the Nautlus 804s used some Blue Circle equipment (and others) as part of his test. They also used Krell on the Nautilus series.

I really think "accurate" describes Blue Circle, so the bass is accurate, which means the whole sound is well balanced (accurate) from highs to lows.
