Yes,
I think the Quantum Physics Noise Disrupter works a little better! I found that the Stone made the sound of my equipment lifeless. It cut into the soundstage to much for me. The Quantum did less to change the sound. My system had a deep black backgound to start with. It works well with my DAC! Great on the highend, but I lost some low level detail. I'm still working with it!
