I know this topic can be answered in many ways including objective and subjective however I am interested in a general consensus as to which FM exciter does not color the sound. This should be very difficult to determine since there are so many different receiver designs out their. The transfer function has to be different if one were to compare all detector vs modulator designs. I'm looking for a common denominator (if it exists).
We know bass is better with dual-loop phase lock loop modulators due to the lower pole of the 2nd lock. What about the pure digital exciters? The specs look great however are their dynamic distortions (similar to SID and TIM) that may make some exciter sound worse than others?
I'm an analog guy that still feels analog can be as good or better than digital in some cases. Digital processors have done a great job of constraining the dynamic range of the program material...does the exciter also make a difference in the perceived sound by the listener?
