Simple mosFET amplifier

[OnAudio]

Can one reliably hear any difference between this amplifier and a lower THD amplifier. A really good amplifier. As you can see no capacitor is used for stability compensation

It is not necessary a good thing.

I can see the input stage is heavily degenerated to keep the gain low enough to maintain stable.

The sound should be OK. Anything below 0.5% THD, you probably won't notice. (At least for me)

Why settle for 0.5% when 0.005 % is not difficult to get now.

We use graphs to reason, but what do they mean?

I don’t know.

Are you the designer? Probably you can share some philosophy behind this design.

Here are some IMD plots

Very similar IMD thd performance to B&W Active 1s

This is one project that has become more popular than I thought , deserves a clap 👏👏👏

This plot is for a mod with 330Rx2 LTP degeneration

It looks as a powerful amp.
How many Watts?
