timbre -- if two different sounds(not sine waves), have the same pitch and loudness, then by definition they have different timbre.
Extreme timbre -- 90db 440Hz_A on a Piano vs. 90db 440Hz_A on a flute
Subtle timbre -- 90db 440Hz_Piano on a TD15M vs. 90db 440Hz_Piano on a Altec 416 AlNiCo

constant directivity speaker you don't know what you are missing!

I've already said that... just these numbers make me having daymare. A lot of common DACs have 0.001% (thd+n) distortion but we won't get 0.001% (thd) at 100dB with any speaker drivers. Gonna sit and wait some revolution coming.

Its quite shocking looking at some loudspeaker response graphs.
We have an amp that puts out 0.0001% distortion and a speaker that is all over the place.
All we can do is buy better drivers or tolerate cheaper ones.
A speaker is pretty complex device with resistance, inductance and capacitance, so its not surprising it isn't a precision device.

I have been lucky enough to listen to many CD systems including synergy horns and dipole. My own setup uses a dipole midwoofer and SEOS horn. So my preference is for CD

However, the most important upgrade for me was broadband absorption

As I said CD is just one piece of the puzzle

I have a feeling that the mechanical distortion and electronic distortion can't be compared on the same table. My ears seem to be much more forgiving for the mechanical distortion.

Edit: And digital distortion is the ugliest distortion to my ears...

Indeed, my first immediate answer was:

1) brain
2) room ( anyone experienced a stationary wave ?!)

Why do you need a speaker with 0.0001% distortion?

The sheep have been led astray!
If you listened pro audio drivers that sound honky and resonant but measured good, i would attribute that to very lousy executed xover.

THD may be the red herring, HD not quite.

moguće

Crossovers were mine but ive also heard in a $$$ jbl speaker

But i can hear that spider/ cone/ surround resonance on many pro drivers when others cant. Others say it sounds "dynamic"

HD is a red herring when people argue between 0.001% vs 0.1%
