The Gryphon Colosseum requires a 20 amp circuit and can pull up to 2400 watts from the wall.
“Can pull 2400 watts”, would be absolute peak, and if the breaker doesn’t blow, then it will be pulling less than 20A.
In a small room, I doubt it would be push out more than a watt of power to the speakers… but let’s say it is 10W.
Maybe it draws 5A at idle… there should be a spec somewhere.
Yes, the amplifier has huge capacitors to bank power and the Niagara also banks power to provide the amplifier with instantaneous current.
I asked Perplexity for an explanation:
“Yes, the AudioQuest Niagara 5000 power conditioner does keep a reserve of power for amplifiers connected to its high-current outlets. It includes a bank of capacitors that can supply up to 80 amps peak for 25 milliseconds, ensuring that power amplifiers can draw the instantaneous current they need to handle musical transients without experiencing current compression[4]. Additionally, it has an instantaneous current reservoir of over 90 amps peak specifically designed to support power-starved amplifiers[6]. This feature helps maintain a low impedance and provides the necessary current for high-demand situations, ensuring optimal performance of connected amplifiers.”

The idea of needing instantaneous current, seems a bit misguided.
The amp already has a power supply with capacitors inside of it… unless it is running way up on the SPL power/volume side , then “what the external Niaga
The Gryphon Colosseum requires a 20 amp circuit and can pull up to 2400 watts from the wall.
“:Can pull 20A is worst case.
The SPL would need to be railed to get there, and if one is not throwing a breaker then it is not pull 20A consistently.
In a small room, the SPL would be shockingly high.
So we can call it 1W of musical power, or maybe 10W if we really stretch it.
I suspect that the input would be 5A, but there shoudl be some idle current, or some power at idle that ne be used for the low end.
Yes, the amplifier has huge capacitors to bank power and the Niagara also banks power to provide the amplifier with instantaneous current.
Many amps have a massive capacitor reserve.
If the input is coming in at 50Hz, then the 25 milliseconds sort of defines the dead time of an AC sinewave.
Those amps would seem, in theory, to be less affected by an external buffering power supply.
Does your system sound different when the power amp is plugged into the wall, than into the Niagara?

Let’s set aside whether that power conditioner is helping…
I think that asking Gryphon if their amps can run at 115v/
50 Hz could be worthwhile.
That is not the same as 110v/
60Hz, and if their transformers do not like 50Hz compared to 60Hz, then that would be good to know ahead of time.
I know with motors, some of the newer ones can operate at either frequency, so I assume that transformers in the amp may be similar.
They are either using different power supplies in different regions because they use different transformers, or to limit grey market trade, or for something else.
Many other manufactures use the same transformer, and change which taps are used depending upon region.
So Gryphon is different.
It would be a shame to find out that the amp cannot run (and last) on 50Hz… In that case, it is worth more now, than it would be later.
This paragraph, from their manual, frightens me:
“
Your Gryphon unit is especially made for the AC voltage of the country to which it has been shipped. If the voltage has been changed, the warranty is void and the product may be unsafe or mal- function.”
