> is response characteristics and sound quality "unpredictable" if we limit the bandwidth and pick a "high quality" (however we might define this) transformer whenever the secondary is unloaded....Good question! Sadly, I think the answer is "yes," good unloaded results can't be achieved reliably as a result of those two factors. Generally speaking, transformers fare best into an open load when they are A) designed for a relatively low operational impedance and B) transforming a relatively low frequency signal. Think about the test you read being performed on an FS-100. Sweep it with a couple mV through the 8 ohm tap and measure the response at the 10K output. Now, try it with a 10K cardbon resistor on the output. I'll bet it's as different as Cadillacs and Corvettes. :)
