I recently bought a couple of books: "Data Conversion Handbook" written by the folks at ADI, and "The Circuit Designer's Companion" by Tim Williams. Both have extensive sections on proper digital, analog, and mixed circuit design techniques. It seems to me, after reading these books, and browsing through "The Art of Electronics", the last thing that should be worried about is LED noise. Hell, poorly matched resistors alone, not to mention regulators and voltage references, can account for 1/2 LSB error in 16-bit converters. It makes me think the difference between DACs and amplifiers are probably mostly due to how well the circuit is designed and laid out, not the specific technology (i.e. 16-bit vs. 24-bit, upsampling vs. NOS, etc.). Now I understand why DIYers often scoff at the typical audiophile tweaks, like buying $1000 cables or vibrapods. I've decided never to part with another dime of my own money toward these things, unless I build it myself, or at least, know how it was built.
