What are the best speakers you have ever owned and why?


I just recently recieved my long awaited Shahinian Diapason 2’s from Vasken And they are absolutely spectacular! This got me thinking about my long journey to get here. Bless my wife for putting up with the many many many speakers that have passed through. The lifelong saga began with Magneoan MG 1’s back in college which were replaced by Dahlquist DQ 10’s. Then we traveled down a long road of speakers and systems. Magnepan Tympanis, Misson 770, Randall Rsch DQ10’s, Quad ESL single and stacked, Acoustat II, rogers LS3/5A’s, Linn Isobarik’s (2 pairs) B&W 801 Matrix, Hales Signature, Martin Logan Monolith2, Apogee Scintilla (1 ohm) Apogee Full Range, Theil SC 5A, Egglestonworks Andra, B&W Nautilius 801,Quad 63 and some I’m sure I forgot! Each speaker had its virtues and flaws but oh what a fun and a times frustrating trek! I think I have finally found my speaker to take me to retirement they do everything that I value wonderfully . They are detailed without sounding so, very dynamic, they have great low end reach, power and detail, are open sounding like a planner, their tonality and timbre seem spot on and they sound wonderful on any kind of music. Tell me about your journey!

In more or less chronological order:- Smaller Advents- Acoustic Research AR 12
- ADS L710 (still have them in BR system)- Infinity RSII- Magnepan MG12 w/ REL sub
- Infinity RSII back again- Infinity IRS Gamma (these were probably the best...only sold them because of reliability concerns)- Gallo Ref 3.1- ML Ethos- ML Montis (I really like these...They can do some things better than the  Gammas)
As you can see, I am very much a panel / dipole person.  Also I have run a few vintage speakers in my BR vintage system, Klipsch Quartet, JBL L100, various other ADS, Infinity RS4.  The ADS L710 have taken on and defeated all challengers.
Rich, I had both Quads and Magnepans in my music room.  The Quad 2905's stayed.

They are not shrill.

It was not until we hooked up Magnepan products that we finally realized that NO box or HORN or ELECTROSTATIC or RIBBON or any combination of these reproduced sound as accurately as Magnepan products. 

How did you actually determine this?
I ask because audiophiles, many of whom have wide experience listening to different speakers, often disagree on which speakers are more "accurate" based on their own subjective impressions.And it also depends on "accurate to what?"  An "Absolute Sound" type of accuracy to the sound of live unamplified music? Or accurate in a technical sense (which would involve measuring distortion).
