Vandersteen Model 7 $45,000 per pair. I got to hear them in two different settings. Just amazing in a hotel room at the RMAF great experience. Then in a treated, well set up living room of a local dealer. Just sat and listened for about 50 mins kind of in disbelief.
It is kind of nice to know what you can strive for even when with amplification and sources it was around 150K + system and I am not going there just yet. http://www.vandersteen.com/asmodel7review2010.pdf
Wilson Alexandria driven by a pair of very large Krell mono blocks and Wadia front end and all wired with Transparent cables. Easily $1/4M (and probably closer to $1/2M). Bought a lottery ticket that day, but just didn't pan out.

Aerial Acoustics 10t's that I auditioned at Audible Elegance in Cincinnati around 15 years ago. I later purchased Aerial Acoustics LR5's that I still own. I guess my kids will fight over these when I die.
