Any modern line level source with an output imp below 1k ohms should be capable of driving an autoformer, and any amplifier with input imp above 10k connected to it can realize its full potential, even with longish IC's. Devices outside those specifications may induce matching difficulties with any preamp. I imagine there are fussy sources and amplifiers that are unsuited for use with anything but the most benign, accommodating preamps.
Producing excessive gain and then throwing it away never made sense to me. That is exactly what most powered preamps do, at the expense of power consumption and additional distortion and noise. Unless a system has a low level source such as phono, there isn't much need for an active preamp.
Peace,

berate is 8 and benign is 9
