For us it is better than the Fishman Piezos, less harsh, less boxy. And for us, much better than a 2 times more expensive DPA as it is a pickup, not a microphone, so no any ambience comes throughout.
In these circumstances with this device You can make a superloud well-soundig violin on the stage and the and to the public too.
The sound is very far from a well mic-ed studio sound, but not bad. Much better than the fishermans I know.
