As an EE, my opinion is that transformers are the most logical choice. They convert impedance and voltage inherently which makes them perfectly suited for step up of small voltages. Transistors can do it too but aren't nearly as elegant a solution, either in terms of physics or design.
But I am not a vinyl guy so I haven't made any direct comparisons. It probably depends on everything anyway so I doubt you can get a clear answer to your question.
