Hi everyone,
Ive been tracking this exciting conversation for some days. One from outside may think this is weird, we are making a lot of air about some sound-description without getting to the point. Im (or was) normally more rational. And if I read something like that years ago id just leave that page 
Now, in the beginning i wrote, there is not much description about Goto Sound in the web.
I understand now why. There actually is. Like "oh that air, that soul, that mystique aura of plasticity...." and I thought "and what? wheres the point? speak sense, cut the BS"... and that made me think there is no (serious) sound description of Goto.Well then I heard em and i cannot do it any better 
hehe. There is nothing wrong about Goto and it would be an ordinary boring thing if not after 30 minutes it suddenly soaks you into the rabbit hole of excessive joy that is hard to put in words. That just for the ones reading this here thinking the same "what the heck theyre talking about" ...
OK. My 2 cents on Romans earlier words. Thats right, i mightve been influenced by other things than the prechamber, i didnt have a comparison.Let me add, i mentioned the speed of sound to Klaus. Then he mentioned the chambers. And that he had visitors that where so inspired that they copied the whole 1:1 and it didnt sound right. It turned out, they used a classical prechamber. So that ruined it...Still i believe i mightve also heard to 100 squaremeter "hall" that basically lacks all the usual 40-120 cycle room modes that bounce and decay into headache in any normal small room. Thats my assumption.
Next, on the later posts, i was kind of laughing that of all possible paramters you guys first attack the suspension.Well Klaus himself said Goto sounds like that because of its huge magnets.To me that all makes little sense. Suspension and magnet shouldnt be overestimated. Especially that no matter how big you scale any magnet in its physical dimensions... it will not guarantee you any bigger force in the gap reaching the voice coil. Coz thats a lot bound to efficient concentration of flux by hard strong special iron etc, tiny gap size, etc. So if you look at the Goto specs, their magnets (though big looking) are not any stronger than the usual JBL, TAD, Lowther, whatever...
I was thinking about it though. The general setup of good horn design, many ways to run only very few octaves per driver.... etc prevents a lot of coloration by principle (honk at the bottom, breakup on the top). That explains to me the general cleanliness and lack of any disturbance or coloration.Still, it doesnt play "sterile" like a TAD. I assume 2 things to blame. One is the titanium. That rings way earlier, resulting in very little very short decay resonance already octaves below the typical breakup point of a specific diaphragm size. As they run all very narrow bands like <=2 octaves, and a very constand growth of dia-sizes downwards the bands... it likely distributes gentle resonances across the whole audio spectrum evenly distributed. With a scale so small you cant distinguish a coloration standing out to annoyance, still feel this vibrant something adding a spice to the colors like that rough texture. Almost smooth, yet exciting.
The other thing that may contribute and really sets Goto apart from usual compression drivers, is the "compression".Normal drivers and phaseplug design is so much different than what Goto does. At least nowadays. Goto still uses compression chamber design from WE times like half century ago. They play the whole diaphragm against a flat blocking surface, squeeeze with incredible high compression through some holes. No good in modern perception. That may cause a normal working design that only in case of sudden dynamic peaks of very short & high level create second harmonics and even IM distortion. That would explain the special dynamics in perception.
I do not want to write negative. Just to find a rational explanation.
