OK, so I'm "ranting," and "high," and your spectrum analyzer can measure timbre. Very good, Adam! Funny, I've never seen an audio review which used a 'frequency analyzer' to compare two components for their ability to accurately reproduce timbre, although I have read many where the human reviewer did make such comparisons. Why bother with a messy 'wet' and imprecise piece of equipment like a human hear/brain thing when you can use a 'frequency analyzer' to obtain an objective, verifiable and precise measurement of an audio component's ability to accurately reproduce timbre?
