My definition of warmth I actually hear in live symphonic performances all the time. I think the hall can influence this quite a bit. One thing I never hear in a live performance is false sense of detail we hear in many systems. I would say the real thing actually sounds dull, slow, very rolled off and somewhat neutral. I never hear triangles, brass, anything for that matter sound as bright and detailed, the highs many talk about, it does not exist in live music ime It just goes to show how we all hear different. Very interesting thread.
