TAD Vs B&W 801, 803
TAD is more tonally balanced, coherent, easy to place/work with in suboptimal rooms. Holographic soundstage of TAD cannot be produced by b&w. TAD engineering may have figured out how to engineer a emotional response, figured out some esoteric sauce.
801 can feel more, dynamic, latest rev exhibits some spatial qualities, quite intriguing. Guys who have exposure to spatial or object based audio (atmos, auro, etc) will catch this. I don't care for its skewed (for my tastes) tonal balance, but, it is their signature, not that they are incapable or lack the aptitude to engineer something else...which should have appeal for others... could be harder to work with in suboptimal rooms.
Listen to both and decide what appeals to you more.
How did they compared to b&w 800 series speakers?
