Are future improvements in Amp/PreAmps slowing to a crawl?

I hate to break it to you, but stevecham is right. The speed of sound through air is directly proportional to the temperature of the air. You cannot make ANY assumptions about the speed of sound through air without considering it's thermal kinetic energy. The problem is with Roger saying stupid things like this:
"Changes in the playback speed of the music signal generates harmonics. Air never alters the speed of the traversing sound waves - neither should the amplifier. If you can stabilize the velocity of the amplifier you have simulated that property of air. This is readily recognized by the brain." 
The speed at which the diaphragm of a driver moves isn't dictated by the speed of the electrical signal passing through the voice coil. It's dictated by the rise and fall of electromagnetic waves traveling nigh the speed of light. The rise and fall of those waves in the time domain is what gives rise to frequency, not the speed of the electromagnetic energy. There's no reason to believe that any amplifier significantly manipulates the speed of electromagnetic waves at audio frequencies. He's suggesting that circuits can act like prisms and that's not what circuits do. Just like waves on a body of water, small waves ride atop larger ones. If a small wave shares the same relative position and vector of a large wave, the small wave simply rides atop it. EM waves do the exact same thing through transistors. They don't apply gain at earlier or later times based on frequency. Again, he lacks proof. Not only can he not prove he's solved a problem, he can't even prove the problem exists. 

My preamp sounds great it didn't crawl using CJ ET5 maybe upgrading to ET7 soon.Enjoy!!

Costco_emoji, obviously I’m referring to standard temperature pressure at sea level. You can ignore the kinetic VELOCITIES that Steve was trying to promote. I never said the speed of sound isn’t a function of temperature, Mr. Smarty Pants. Stop trying to put words in my mouth. The speed of sound is a constant at standard temperature and pressure. In Roger’s case you can assume any temperature or pressure you want. It doesn’t matter. He wants to preserve the speed of sound - whatever it is under the conditions at the time. Duh! The recording could have been made In 110 degree heat during a thunderstorm. It does not (rpt not) matter. Follow?

"Ok, so what are you going to do, slow down the propogation of an electrical audio signal to 750 mph? That in and of itself, if achievable, and I doubt it, would time distort the signal even further in the electrical domain."

>>>>Uh, I get the feeling you’re not following the discussion. He’s not saying that at all.

Then stevecham wrote,

"And, I challenge that air does not time distort music; there are microbar or even nanobar changes happening in local environments constantly, simply through the movement of air alone. We know how wind direction can easily change if we hear across a distance or not. Air molecules are chemical entities; electrons are first generation leptons. Each is governed by a VERY different set of physical properties."

>>>>Again, yours are Strawman arguments. He’s not saying any of those things. You are jousting at windmills. Furthermore, If you had been paying attention you’d know that electrons have practically nothing to do with it.

Then stevecham wrote,

"Changes in playback speed change pitch."

>>>>>So what? You might as well say the sky is blue. He’s not implying playback speed changes. Hel-loo!

You're an idiot. If we need help with Morphic fields, Scientology, and new age hocus pocus we'll look you up. Roger is claiming circuits alter play speed AND he claims that's the source of distortion. That's pure BS. 
As for you claiming air is considered motionless, it is only because there's no alternative. Just putting sound in the room manipulates the pressure of the air at any given point and acts like it's just some presumed constant, which it is not.
