a 3 way design speaker with the ESS Heil type sound

Thanks again everyone. 
I think tomic601 and decooney are on to it. Extended, detailed bass, but with mid bass slam. Beautiful dipole fast and accurate highs. 3 way with HEIL. I never thought of a high current amp. I was thinking tube preamp to tame upper midrange beam. 
I learn something from this site often. Been lurking and learning. Only commented a couple times. 
Still interested in those beautiful Cinnamon Audio speakers. I don’t think they are available to my budget. But, I can hope. 
Is the Qualio midrange ran up high, or do they make good use of Mundorf AMT?

Does that midrange work for slam and dynamics?

 Thought they made use of full range midrange. 

I bought a Melton tube amp with P/P KT88s and do not care for it with the Heils.  I much prefer my Yamaha RX-Z9 receiver in "Pure Direct" with them.

Older recordings prior to reworking the crossovers, but that has no effect on the highs.  A quality monitor will easily display the differences.  Levels were matched to within 0.2 dBA with pink noise.

Some may prefer the "tube sound", but at least in this case, I prefer the solid state.

While I have voiced enthusiasm for open baffle speakers, this does come with the warning that dipole speakers often do not go very deep in bass response because the opposite phase front and back waves tend to cancel each other at progressively increasing amount as frequency goes down.  This is true of dipole panel speakers as well.  I am not a bass freak so this is not as big a deal to me as it might be to others.
The original Heil AMT speaker had a dipole AMT driver but the bass was delivered by a more conventional woofer that was not used in dipole configuration.  That speaker had serious problems with the two drivers not integrsting well.  That problem persisted with the new iteration that is out now.  But, other builders have been successful matching heil drivers with conventional drivers so it can be done.  
 

@tomic601 so the MTM w mid bass drivers of 7” or so with a sub makes sense…just my .02$….

That configuration is darn close to my own custom built setup:

• Dual 8" Nomex mid-woofer/midrange
• --Peerless Tymphany version
• ESS AMT Great Heil
• --updated AMT diaphragms
• MTM configuration
• 1200hz crossovers, custom
• --isoberic chamber tested
• 92.5 db sensitivity, 4ohm
• Walnut enclosures, not baffle
• Tune ported at rear
• +Dual custom 12" Scanspeak stereo subwoofers

We design and manufacture our own AMT drivers. Our entire line is based on AMT drivers. All of our speakers are OB.
