I own both a Lyra Titan and a Transfiguration Orpheus L. I like both cartridges--the Lyra has a touch more open and airy top end, the Transfiguration has a bit more prominence in the upper midrange. Neither is really a "warm" cartridge, as I would use that term for something like Koetsu wooden-body cartridges (upper bass, lower midrange prominence). Perhaps the Titan leans a bit toward being harder and sounding, but, it also delivers an exciting sound.
I have not heard the Proteus, but, given Transfiguration's recent track record, I am sure it is a fine cartridge too. I haven't had my Transfiguration long enough to compare it with the Titan for stylus wear, but, I can say that every Lyra I have had has lasted a VERY long time.
