The best speaker you ever heard?

Vandersteen 5a, with the usual Ayre or Aesthetix or ARC gear (all three were available). Quad 988 side by side ever so slightly veiled in comparison. I will audition 57's soon. Vandys had great imaging, soundstage, and very importantly, suspension of disbelief and disappearing as speakers. Revel Studios and Dunlavy IV's were very close to the above. Magico 5's with EAR electronics and Clearaudio statement.. though the Magicos were indeed stellar...when factoring in price... I call them Stupidos. When 45k Vandy 7's sound reasonable...then electronics prices are entering the realm of tulipmania.

Tidal Contriva Discera SEs, I had concluded that every speaker was a compromise in one way or another, until I got these. And they are well short of the 600 hours of breakin.

My main question now is finding an amp to get the most out of them.

I have a pair of Infinity MTS right now in a simple system with an Olive server feeding a Tact 2150XDM. Sounds pretty outstanding.

The McIntosh XRT2K at the McIntosh Labs headquarters in Binghamton N.Y. in March of 2008. Of course driven by Mac 2000 watt mono amps and associated Mac equipment.

fritz carbon 7's are the best ive heard
