So it should then be possible to construct a crazy-wattage audio amp (3000+ Watts?) without a transformer (i.e. the most expensive component) if you use the 240V mains (U.S.A.) on a dedicated pair of circuit breakers and directly rectify the mains voltage so you can have a split supply.

Although C-core audio transformers for tube amplifiers have had fairly wide acceptance (at least in Europe and Japan), C-core power transformers are not common in audio equipment. Photo 8 shows a medium-power C-core power transformer, a single-loop transformer with windings on both legs of the core. R-Core Transformers.

ern audio products and the optimal noise performance is attained when the characteristic “noise resistance” of the amplifier, Rn, is equal to the source resistance, Rs. While transformers are not required, as in tube circuits, a precision input transformer will optimize the op-amp to the source impedance, which is unequal to the op-amp’s Rn.
