I asked this question because the International caps perform, sound and feel
much better than Mallory and Sprague Atom in a Fender Blackface Twin, I dont
know why.
Printed on the caps : HTD : High Temperature Dynamics( for high temperature)
Could this affect the feel and sound in a Fender Twin amp?

In order for there to be a difference, audible or otherwise, you'd have to
provide a meaningful explanation of why one company's microfarads behave
differently to another company's microfarads !

And *then* additionally why the caps in the power supply would be audible in the
sound. It's not as if they're in the direct signal path !

Have you actually considered measuring their value ? I wouldn't mind betting
that the caps you're saying sound better have actually dried out and their value
is a fraction of the value printed on the can. That *would* affect the
amplifier's dynamics. You could mimic that effect by using new caps of lower
value than original.
