Im struggling to understand how having a large Transformer within inches of the amplifiers that are fed by it could possibly have more resistance and losses then having the same amplifiers being fed straight from the wall, assuming the transformer is of adequate size to perform task.
If you have a hypothetical bucket full of electricity sitting inches away from the amp power supply how can that be more detrimental to power delivery then having the amp wait for adequate juice to arrive from the breaker panel, thru the house wiring, thru the receptacle to the power cable of the amplifier?
What am I missing?
A transformer does not generate power, it transfers it from one side to the other. Losing a little along the way as Amir said. You don't have a "hypothetical bucket full" -- you just have a another hose to connect the amplifier to the bucket (wall outlet) on the other side. And the transformer also has limited bandwidth and current capability, usually less than what the wall socket itself can provide.
