So what is the best speaker you have ever owned?

Rockadanny, sure.... if people would do that. But they aren't so it's just another -list your favorite- thread.

Artemis EOS and now Wilson Sophia IIIs.

The best speaker that I have had is my current Salk SoundScape 10s. They have a holographic soundstage of unbelievable depth. They have incredible smooth horizontal dispersion so have the same tone throughout the room. The RAAL is possibly the best tweeter available. Maybe the tightest bass I have heard and it is flat down to 22Hz. They are also the most transparent speaker that I have had. With my Aesthetix Calypso preamp and McCormak amp the speakers can even make the Lawrence Welk show sound fantastically real, even in mono. The price is also very low for what you get. One problem is that they are only of average efficiency. The only other problem is that they are dampable open baffle midrange so they needed proper room treatment for the ambiance wave.

My best is my Soundlab m2's followed by my Dunlavy scIII's.

My current and last set up, Shelby+Kroll Nano Monitors and 2 Woofer Monitors. These give me exactly what I want in music. All of what is described in the opening question and always a huge grin everytime I listen.
