@inna Tell me your speakers and I'll tell you who you are

Magnepan 1.7s augmented by Mirage MM8 small (9" cubes), sealed, very fast subwoofers. Happy with this combo for 4+ years so far.

Lowther Fideleo's with sub. Why: No crossover (except for the sub), high efficiency (sounds great with high quality class a low powered mono amps), transparent, three dimensional, image well with wide deep sound stage.

Magneplanar Tympani-IVa, but my current (and in all likely hood permanent and final) music room is not big enough for them. So I have to get along on Quad ESL and Eminent Technology LFT-8b & LFT-4 loudspeakers, augmented with GR Research/Rythmik OB/Dipole Subs. Not all at the same time, you understand!

Inna, your comment: “There is absolutely nothing in essense you can do to fundamentally change the way speakers sound. They are what they are.“

This is supposed to be a joke, right? There are many things that can change the sound of your speakers: speaker positioning, room, amp power, and more. 

If I put a speaker with a port in the back up against the wall, you don’t think the bass will change if you move the speaker out feet into the room?
say you own a pair of Wilson Alexia 2 or Maxx 3 speakers and you drive them with a 100 watt onkyo receiver, don’t you think the speakers will sound better if you are using a Solution or a 1000 watt McIntosh amp?

The key word is "fundamentally".
I have Michael Green Audio free resonance speakers, also called controlled resonance speakers. They have their limitations, but I don't listen to big scale music and anything at a very high volume.
Michael believes, as I do, that speakers are not only devices but also musical instruments. However, the full realization of this concept is I think nearly impossible. This should be the kind of instrument capable of reproducing all instruments in a convincing manner with full power.
Aside from rhythmical instruments, I like string instruments, starting with the most basic that each of us has - voice. I don't want stuffed speakers or excessively braced speakers, I want them to move and breath. These speakers are also very sensitive to even small changes in the system anywhere - I like it too. Vifa drivers in them are not bad at all, the crossover could've been made better, I suspect, there is some congestion in there somewhere, I guess. Coherence is good. Powerful and tuneful bass from that 8" driver with my amp but not overpowering. Excellent speed and dynamics, involving sound. Not the highest resolution or imaging sharpness but enough for me. Deep layered soundstage with the right cables and power cord on the integrated. Michael's used to be top of the line Chameleon speakers are great if you like this kind of sound, they were made in very limited numbers and personally voiced by him.
