So I bought a European Amplifier with 240V supply power requirement. while it was shipping I installed a 240V outlet for it. I know about the differences between US and European 240V power (not going to explain them here) and most European equipment other than induction motors will run fine on US power, certainly a simple power amp. But my amp (Ayon Audio) is less simple and has a phase detector that senses the plug is wired backwards when running on US power...so I'm looking for other options.
I test ran it on a tiny (500W) transformer and confirmed it works. However, it was severely current limited on such a small transformer. I have a 5000 w transformer on the way. Inexpensive transformer to play with. I'm afraid it will be current limited for spikes (especially playing bass) on this transformer too.
Tube amps especially, but all amps in general, need a generous supply of ready power to handle bass notes. The average power of this amp may be 375 watts but it needs availability of much more than that for short spikes. I run all of my amps on 10ga power cords I have a dedicated 10ga power line for my stereo. Excellent results.
I'm concerned about the output impedance of the transformer. Transformers are good for smoothing out noise spikes. I don't want to smooth out the noise spikes, when my amp needs a current spike, I want to feed it.
So my question is this. can a very large transformer avoid the output impedance problem? I'm specifically looking at 15,000 watts and above, like this one:

Other ideas are welcome too. Power conditioners don't seem to be an option. All manufacturers make European conditioners for Europe and US conditioners for US and making one that is fed by US and outputs Europe would be a one off custom and take an already super expensive component to unreasonably priced.
