... as I said - why being smart when Papa is already smart
Papa is using low-ish rail voltage to avoid the hotspot issue. The IXTN140N30P is not one of the ones designed for linear usage.
If you want to run higher rails then you'll need something different. The IXTN200N10L2 and IXTN110N20L2 look interesting, although they have significantly higher capacitance....
Hi Jeff,
look at the 6moons review of XA25 and you will see that the 140N30P is a is not out of the race....

Oh so true - new research is important and provides a great foundation but always build on that which is done before you.

If you play a 10kHz sine wave, then you are correct. If you play music that has some 10kHz and some 11kHz, then don't be surprised if you do hear some IMD.

"well , I didn't mention Caveat - I enjoy finding logic behind his Smartness"
Absolutely - the pieces of the puzzle must fit 😀
for me - back to square one learning about pucks
Thanks to all of you

as I'm older and older , I'm finding Mithrandir's stance - about working on just one project at a time , more and more clever
though , I'm thinking that he's lying , un poco ..... more precise - deluding himself ...
I fell to sleep last (late) evening reading one of Barsooms , woke up in a middle of the night to waste some DIY Kefir and to hop in Pajamas, read little more ...... then I woke again around 04.00 - dunno did I dream some idea or I was contemplating about , so I simply must fire up LTSpice to check it
so , around 07.00 did go again in bed , and woke around 14.00 , not feeling fresh
always saying - sleep is overrated ...... but only if you have less than 30 ....
moral of this rambling - maybe I need to send e-mail to Pa to confirm my guessing why he implemented 10A protection in XA25 .... but counting how I'm again in disgrace, I know that I'm doomed to proceed without reply
so - I did implemented 10-11A protection in Babelfish XA25 concoction .... even if I'm sure that this block is certainly having idiotproof function , more than it's really needed .... same as 1K output resistor in first iteration of B1
anyhow , it's good for brain 🙂

got to keep that brain young😀😀😀
F4 beast is a wealth of information - don't know how it fell off my radar and even if I only understand a small portion I'll be happy.
You guys are great !!! 🙂🙂🙂🙂

I always thought the 10A protection is because these damned pucks have no current limit by destruction.....
But of course there is a fuse in the mains AC department....

I agree about IMD, but his comments were specifically related to his graph of Harmonic distortion vs frequency not IMD.
Edit: I am mostly expressing some frustration that a person who publishes measured results:
1) Can't bloody notice issues with his own measurements.
2) Shows some level of incompetence with his analysis of his own data, with respect to music and human hearing.
3) But mostly because based on point 1, I have no confidence in any of his measurements.

Just woke up.
Hahahahaha
I will read again.

Is that 10A mains protection or 10A current limiting on the pucks?
Guessing you mean 10A current limiting circuit on output stage.

would I write about bloodypicodumb mains protection?
After my last brain fart, it's safer to be sure.
HD and IMD are generally the same thing when it comes to music. A nonlinearity in an audio device will produce HD in response to a single sine wave frequency alone, and IMD as the response if two or more sine waves are present at the same time.
Music generally contains lots of sines at once, so lots of IMD.
HD is mostly just a convenient way to quantify device nonlinearity.
