Wow - that's some set of speakers there. I love the description (emphasis added):

Note: A-1's are nortoriously-difficult to drive, requiring massive voltage-swing and rock-solid stability into nearly a dead short above 20kHz; few amplifiers at any price are up to the task.

Frequency response: 28 Hz to ultrasonics.

I've got an audiophile co-worker who's wife has finally gotten his habit under control. He's told me stories of going to conventions and hearing the top end speakers (with an equally top-end pricetag), and how they almost capture the "live" sound. Apparently it's the little stuff that gives it away, like the detail of the hi-hats.

The "problem" with developing your ears is that you start hearing defects. It's especially irritating once your ears start locking onto something pervasive, like the artifacts of MP3 compression, or the glassy sound of pitch correction. All of a sudden these problems that you never heard before jump out front and center, and it's hard to enjoy the music after that.
