I was looking into making a high powered audio amplifier and it seems that one of the biggest components is the transformer. I've also seen amplifiers (commercial) run from 12v up to mid 30's, depending on the maker and size.
I've taken apart many large UPS battery backups of 2200-3000 watt rating and even higher. They have very large transformers, usually of 12v or 24V - IDK the KVA rating of the transformers but they are quite large, about 1.5-2x the size of the average MOT in physical size and weight, if that gives any reference. Each unit I took apart had 2 identical transformers.
I also have some 12v SMPS supplied from servers that are rated at 1200 or 1600 watts. IDK if these could be used in the place of a transformer, they are very efficient and were super expensive when they were new, on the price of near $300-400 each IIRC. IDK if these could also be used as the source of DC current.
The reason I questioned if the transformers could be used is because I've often seen transformers for amplifiers advertised as "audio transformers" and they were often much higher priced than same rating normal transformers. I don't know if they are built with special components or something or with different requirements.
As far as the type of audio amplifier, I'm not sure if it would be a A, B or AB class but I would also like to make a class D for a sub woofer amp.
I do have some very well build line filters that were made for communications equipment. These are 120/240v rated and for 1660w/2,700w PSU so they should be able to handle the power for the transformers if the line needs filtered.
I guess if these transformers can't be used for this, I could use them to make a nice sized isolation transformer with 2 of these?
