As a frame of reference, I have a Shure V15 Type IV with a Jico SAS, the Hana SL, and the Soundsmith Aida II (a little up the food chain from the Carmen). No experience with Sumiko carts.
The Hana SL is very neutral, perhaps even a bit on the "warm" side. My Soundsmith cart is more lively and sounds more similar to the Shure. Have you considered a JICO SAS stylus for your Shure? It's a nice and relatively inexpensive upgrade.
