Zanth - the SME arm is quite dry and analytical and often benefits from a warmer cartridge like the Koetsu.
The Koetsu Black is a classic - I've owned one for the last 20 years and I would recommend that you get it checked out and re-tipped if necessary and then live with it.
Some say the Koetsu is slightly bass light, however allied to a SME I would expect it to sound great.
Some refer to the Shelter 501 as a poor man's Koetsu so I wouldn't view that as an upgrade. The Koetsu gives warm side of neutral. You'll struggle to get tight snappy bass with a SME whatever cart you use - it's been described as "plummy"
I think the Dyna carts are a good fit with the SME arm - the 17D2 has stunning responsiveness and in the SME will sound quite tight in the bass.
Cutting to the chase, try the Koetsu Black re-tipped (if you don't like it it's worth far more re-tipped than in need of re-tipping), if that doesn't float your boat try the 17D2 (they're available really cheap off-shore).
I can give you a great contact in Switzerland who re-tips Koetsus at affordable rates - contact me off list if you want the contact.
