Unbelievable

You would like an apology?

OK, here's one Mr Magic Atoms.

I'm really sorry for exposing you for the fraudulent and tireless shill merchant that you are. 

Good enough?


Anyway, back to question at hand, does Yamaha's claim stand up?

"Glossy black piano finish provides improved signal-to-noise performance — and adds to the luxurious joy of ownership"

Or is it simply marketing gumpf?

I'm going with the former, because it's Yamaha and they build some great electric pianos, but a few cabinet resonance charts to back up their claim wouldn't hurt, would they?

Apoplexy accepted.

Resonances are distortion, not noise.

Not exactly. Resonances produce distortion. But you were close, very close. The signal becomes distorted by resonances induced or external. The signal itself in cables and cords and wire is not vibratory.

In the framework of "Signal to noise" which is a measurement, cabinet resonances are not noise, but could present as distortion. If you want to be pedantic magic pebble man, resonances induced that are not at the frequency of the stimulus will measure as distortion. If you are going to be pedantic, at least be right. 


The thread is about speaker finishings. Bringing up what happens in a cable is called lack of self control.
