The best speaker you ever heard?

Got my hands on a vintage pair of Krell Resolution 2 speakers and they have turned my idea of what a home system can deliver upside down...or is it downside up?  Spooky staging, unrestrained dynamics and tonal perfection with uber-palpability!  They blow away the Wilson WP 6's, B&W802D2's and Dynaudio C4's I've owned...among many others.  As clear as Maggie's without dynamic limitations.  For $3300 I hit the lottery!!

One of the most impressive systems I ever heard was a pair of huge Soundlabs, can't remember the model as it was 20 years ago, but the amps were Classe 400W monoblocks, pre was audible illusions modulus 3a, and don't recall the front end.  The speed, detail and transparency were sublime.  I was a Maggie owner at the time so I found it easy to fall in love with those Soundlabs.

Wayne Picquet refurbed original Quad ESL's.  I've had a pair about four years now. 

Either every other speaker is right and the original Quad is wrong or...... 

I used to love the Quad ESL's with warm tube amps.  My tastes have changed greatly over the years, but I do have great memories of that speaker.  

Charney Audio companions with Lowther Dx-65 driver.  Folded, curved, back loaded horn with incredible dynamics, linearity, coherency, immediacy. After 45 years in this hobby I realize single-driver speaker systems sound so more lifelike than anything else. If your in the nyc area you must go audition these.
