Since we started labeling, let me put my labels:
"non-analytical" = not clean
"musical" = colored
Let me explain. Sound without distortion might seem analytical or lifeless since distortion adds "kick" - just compare distorted guitar and clean jazz guitar. I even read negative user opinion of my Benchmark DAC1 that claims that each instrument can be heard independently instead of preferred "sound blob".
As for appreciating music more by musical people who sing in the shower - creating, performing and receiving are completely different things. One doesn't have to have music inside (soul as you called it) to be able to receive it. More, people who create music often have complete disregard for good sound. Same often goes for performers.
Musicality is often associated with warm sound that has enhanced even harmonics therefore colored. Warm sound might be good for guitar or voice but is not so good if instrument has complex harmonic structure (piano, percussion instruments). Piano sounds, on very warm gear like out of tune. That was the reason why Benchmark's technical director John Siau did not want Benchmark to sound warm. I remember reading about test conducted with Benchmark and few other DACs in recording studio. Benchmark was the most accurate, according to sound engineers (also audiophiles) and worst sounding according to regular users. To me Benchmark sounded too clean at the beginning as well - made impression of missing instruments in known recordings. One has to learn to listen, I guess.
Let me introduce other label (not mentioned so far)- NEUTRAL, CLEAN, TRANSPARENT, RESOLVING, PURE
