If you are willing to sacrifice just a little detail for warmth, liquidity and timbre I would suggest that you look at the Grado Reference Reference 2 (not a typo - that's the model). This is one of the best sleeper high output cartridges on the market.
I'm currently running the low-output variant of this, and had a 2M Black, that failed when the pins just pulled out of the body (out of warranty).
The Black is a fine cartridge, with a great amount of detail, but I prefer the Reference 2. Lots of detail, but greater warmth and realism, to my ears.
