You can get highly detailed with a good Ortofon cartridge but you won't get warmth as such unless the recording has that warmth.
If you were just looking for a something that is... highly detailed but warm sounding cartridge with generous bottom end, then i would whole heartedly recommend something from Phase Tech/Phasemation. However those will definitely not work in a magnesium SME arm as they need a heavier arm or the tracking is poor.
