That's just not true:
1. The biggest distortion contributor is the VAS of course
2. Any class AB amplifier is actually a class A provided that the output signal's excursions are small enough to not go beyond the boundaries of transistors currents conductivities.


I wrote the second statement because if I remember, till now no one mentioned the output levels and if there's (any) correlation between them and graininnes of the sound.

And I ask, could a superintelligent alien who knew all the physical mechanisms of sound and terrestrial amplification devices, but nothing in the human ear, make a good amplifier?. My answer is yes

one more cent,
grainy sound could mostly comes from cold active amplifying devices, no matter ss, tube, AB, A, etc, after 40 minutes things are different (the ear is used to?)

Bought a little cheap DAC. Heard one year. Removed then the analog-output; this one cs4344c - Google Search
drives the 2-stage-SE. A dream! Compared with the original NO grain;-) Power, punch, cleanness, clearness, homogenity, endlessness ... a dream, a dream, a dream;-!!!

Is the word "granulated" something new to describe the sound? I have once seen a "dictionary" of audiophile terms, but I don't think I remember this one .... I thought that describing " treble sharp", bass "round", or "silky" midrange was enough! Blessed are the lucky holders of "golden ears", I applaud your fantastic facility to describe sounds with words ! What would we do without them? This system sounds very natural, or this system sounds unnatural seems to be not enough, you have to be more specific, isn't it? We used to say "Those treble punctures my tympanum," or "those bass kicks your *** ." How ? What is outdated, very widespread and does not work? Oh sorry then. I will continue learning and updating myself .... What do people mean by a "grainy" sound? | Steve Hoffman Music Forums I found it, I'm amazed, I didn't think there were so many ways to describe the indescribable ... Grainy : A moderate texturing of reproduced sound. The sonic equivalent of grain in a photograph. Coarser than dry but finer than gritty. Stereophile: Sounds Like? An Audio Glossary

The first question to be answered here is what *is* 'grainy sound'? What are its characteristics? What does it look like?

How does one learn which types are “noisy”. Is anybody keeping a table of these?
