Jitter can, and does, take many forms... It can be totally random, it can be related to the bit patterns in the transmitted stream, or it can have a fixed frequency like 60/120 Hz from the power or some harmonic of a clock. In any event, it is possible to inject it in a controlled manner, to test it's audibility. The simplest way would be to inject the jitter signal into the VCO control of a PLL I would expect that we would find that the audibility of jitter depends on both the amplitude and the type. We could probably tolerate much higher levels of totally random jitter, than a single fixed frequency peak. FWIW, I agree Phil, that the DAC has a bigger impact on the sound, than the jitter, but then I've only ever bought products that had excellent jitter rejection as well....
