I'm confused. Have you linked this so people can laugh at someone who believes he can hear things 130db below the signal or are we taking this seriously?

Serious - open for discussion.

I think he is somewhat confused about a few points, but his goal is to bring some ideas that are not usually in the world of EEs to them... you can hear signals way below the noise floor... under some circumstances.

Was hoping that folks would find this interesting to discuss...

yes it is amusing/distressing to see "outsiders" (mis)interpretations of a subject you've spent some time studying – the different perspectives can be helpful in getting us to think about why we believe something

noise isn't a single number, you need the full spot noise vs frequency info, signal spectrum, knowledge of critical bands, masking, outer hair cell nonlinear amplification

the numbers for the ultimate range are impressive, but most music is experienced in situations with relatively high nose floor compared to our threshold in quiet after minutes of accommodation, above the level that saturates the outer hair cell amplification

an interesting extensively DBT tested result is seen in psychoacoustic compression algorithms, mp3 and better only use ~7 bits per critical band to achieve "transparent" coding of music

Dude, I don't have any of that knowledge at all, I just turn the volume up past "7" and let it crank! My friend says that until you get the knob to "10" it won't hurt the amp or speakers, right?

Both of them made from sands and metals. From my research, they have different way in driving loudspeaker, for example if a tube amp using high NFB they will sounds like not tube amps.

Thanks for that article, and tube amps are not the one with best sounds among all type of amplifiers.
You may have tube sounds coming out of solid state also if you make it driving loudspeaker like tubes did. First the informations of differences between tube current source and transistor current source in any condition should fully collected. Then advance to the next step, to make transistors do the same.

Heheh a waste may be.

No. I totally disagree. My tube amps with high NFB, low THD, low output resistance, sound like tube amps. It is the proof that tube amps sound warmer not because hey add some "warm" distortions. But because they don't add "Cold" distortions. My SS amps that don't add "cold" distortions sound also "warm".

Its well known that valves put out more second harmonic distortion than SS amps. I have even built soft limiters to emulate valve type distortion.

SS amps can sound very cold due to lack of distortion.
