I didn't find the Orbe clamp upgrade to be as noticeable as a big upgrade in cartridges, but the ability to easily adjust the down force on the record does Help to fine tune the damping of vibration energy. It's generally a subtle improvement but noticeable nonetheless. At least with my setup.
I also like that you don't have to force the suspension springs down when you torque the Orbe clamp. With the stock clamp you have to apply a fair amount of down force and that can't be good for the springs over time.
I consider the Orbe clamp upgrade to be worth the cost, especially when you think of it in terms of cost per record play. If you keep your Gyro SE for 10 years it amounts to pennies per play. Well worth it.
