I'm not saying the detrimental sonic effect is huge - it's simple a case of covering all bases for complete piece of mind. I am somewhat of a perfectionist

Noise always exists, no component available will not generate noise. I suspect a forward biased LED will be no noiser, and given the correct choice less noisy that the two diodes in series that Glenn seems to like using in his preamp cathodes.
