Would someone kindly explain the audiophile term "warmth?" Most appreciated.
Cheers!

J. Gordon Holt, founder of Stereophile, is the originator of subjective audio review and development of a consistent set of descriptive terms. Here is his audio glossary, including the subjective audio definition of "warm."
Raul, I disagree a bit about warmth in live classical concert. People described various concert halls' characteristic and warmth is certainly one word that keeps cropping up. I have not heard all that many great halls around the world but I would say for example that Vienna State Opera House certainly sounds warmer Grosse Festspielhaus in Salzburg which is warmer than Metropolitan Opera House. The old Orchestra Hall (before renovation10-15 years ago) was quite a bit drier, cooler in tone than Carnegie Hall and so on. Fazioli piano is crystal clear, cooler in tone than Grotrian which is more woody, darker/warmer tone. Warmth is a coloration for sure but I am not sure if it is neccessarily an abberation. What should be use as a standard in neutrality?
