I have no doubt that what you heard was a deterioration of sound quality, however, unless you actually measure the cause it could well have been some other interaction rather than current limiting. To say it was currently limiting in your application is at best a good guess, which is a place to start to measure.....but it really is only a guess and not a fact.
You resolved your problem by removing the component and replacing it with something else. In the end, pleasing your ear but actually not determining what was causing the poor interaction. Which doesn't really matter on a 1 on 1 case basis as long as it works for you but should not be extrapolated to others with unverifiable root causes.
