"Audiophile" is not a term that denotes any particular level of knowledge or any particular level of knowledge about this hobby. There really are no standards for many of the terms that you refer to -i.e warm for example is a term that refers to a quality of audio presentation that is more relaxed and mellow as compared to "in your face", blaring, etc. The real key to being an audiophile is finding audio components that produce the sounds that please you. You will never get official recognition that you have become an "audiophile" -it is something we self appoint ourselves as becoming an "audiophile" and what the various musical qualities you name above actually mean or refer to is somewhat subject to each one in this hobby.
Find equipment that you like and enjoy, be prepared to repeatedly spend more that you normally would like to spend to improve your system and the sound you enjoy and you have then become and "AUDIOPHILE" - welcome!
