Bragging about the size and stiffness of your power supply?

Such is important only to those with challenging speaker loads or those who wish the best sound quality.
Of course it's important, but how much is too much? With a tube preamp, though, I can understand a bigger supply would be critical. If power is used efficiently, perhaps not so critical.
I have a passive preamp, so no supply needed at all! System is very dynamic, and I've had quite a few different preamps, including tubed.

I've never encountered "too much". For comparison, the base Mauro design has two joules of energy storage (27,200 uF @ 12V) according to the schematic. My earlier comment was based on an implementation of that design I found that had 20 joules (60,000 uF @ 25V).
By comparison, the Stasis 3 has 105 joules and the pair of VTL amps, 500.
My experience is that high storage energy amplification provides better resolution and dynamic impact. Back in the 70s, I did some DIY work to an Audire power amp. Tripling the capacitance made a noticeable difference.
Everything is relative.
I wonder if that Stasis supply is the same as the 400A? Bigger? Nelson does like those big caps, and using, sometimes wasting, all that power.
It has been demonstrated that additional capacitance in the MyRef and other chip amps does not necessarily yield better sonics. That might be true for more than just this circuit, but in many other cases where commercial considerations led to undersized PS, more cap is indeed desirable. You're right: it's all relative. These things are not intended to break windows. But they do make really sweet sound, and plenty of it.

Sorry to hear that.
