Blueswan is correct, except for the Equi-tech wall units. These are very large very high KVa. The Q design is for high current (particularly useful for amps). Their smaller component type units, I would agree should be left for source components.
The transformer accomplishes two things. One it creates balanced lines (+/- 55V) rather than 110V and a neutral. These are out of phase and thus have the noise cancellation properties mentioned above. The other thing a transformer of this type does is isolate the power for the audio room from all other noisy electrical components in the house. Separate circuits will do this to some extent--but not entirely. These transformers really work in that regard.
Blueswan is correct for the most part about current limiting devices, except for the Equi-tech wall units. These are very large very high KVa. The Q design is for high current (particularly useful for amps). Their smaller component type units, I would agree should be left for source components.
