I believe that CM700Ti sounds the same to CM700. I also seen colored CM700 (do not remember exact index) in Tokyo, so it looks like series of the same phone in different cases. Probably, there is a little sonic difference between titanium and aluminium casings. But I was not able to discover it comparing CM7 vs CM7Ti.
Anyway, we do need more opinions on CM700 sound just for averaging alternatives.

indicates that Ti version is more detailed. Titanium must have different harmonic resonance.
