To me timbre is the most underrated aspect of sound quality. Without it, instruments don't sound real no matter how well the gear performs across all other audiophile criteria. However it's often omitted from reviews, perhaps because it is more subjective than many other criteria. So with this thread I would like to suss out what precisely is meant when we talk about timbre (and differentiate it from tone and texture). I would also like to learn whether or not it can be measured objectively and what differences in gear manufacture are responsible for these differences (e.g. does the wood in wood headphones really lead to better timbre with wood instruments?). Finally, people could recommend timbre HoF gear and gear combinations here.
