If you live in a drop ceilinged basement with a big TV, leather like vinyl furniture, eat a lot of processed food, and do your laundry once every few months, I don't think most single women will be impressed that you have say, Zu Dominance loudspeakers and cable elevators.
However, if you man about town kind of a guy, who knows what you want in life, and are discenring and meticulous with your interests and personal belongings, I can assure you that single women will notice and appreciate good audio equipment and speakers.
Of course, this has to be introduced by focusing on music, not hardware, in the same way that a woman mgiht first notice the "color" or the interior of your Maserati.
But despite women's alleged indifference to hardware, they will be more impressed with the Maserati than they will by a Toyota with the same color and interior.
Hugh Hefner always featured elaborate audio systems in his early "bachelor pads" and in my opinion always did pretty well with girls.
Cheers,
