When I attend live performances(unamplified jazz groups) they consistently sound rather,full,rich,round toned and yes warm. Even when they play very fast tempo music it`s still very full bodied and preserves a sense of ease and density(same is true of classical music programs).

Quintessentially, this has also been my observation. Personally, I advocate a closer examination of the recording process and what it yields.
