Magnepan MG3.6R's with the Sonic Frontiers Power 2 amplifier. Maggies are among the best sounding speakers available, but they are ridiculously inefficient. The 3.6's require about four time the power of a pair of Vandersteen 2CEsigs to achieve the same volume level. Low power tube amps need not apply.
Audio Nirvana 8" single driver speakers. These drivers have a rising frequency response below 1khz. Even with a bsc filter they are some of the worst sounDing drivers I've heard. I'm talking BRIGHTANDINYOURFACEBADSOUNDING!
Here's a situation we guys with understanding wives and girlfriends DON'T have. I feel sorry for any man who has to come home from work every night to handle this kind of problem. Much better to hear "OH, you got another pair of seven foot tall speakers. COOL!!!" But I do appreciate her woofers.
