What is Warmth?


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

Agree with Raul and add that warmth in a positive sense is communicated as musical flow, a phenomenon of dynamics and timing more than frequency response.
Musical instruments themselves can have a have warmth characteristic also. Different woods used in a violin for example. It's not only tied to sound of an audio system.
