I auditioned the Sopra 3 vs. the Wilson Sabrina at the local dealer and it wasn’t even close. The Sopra 3’s were far superior. In fact I would rate the Sopra 2’s above the Sabrina.
I know the Sabrina’s have received a lot of favorable reviews, but to my ears the Sopra’s are in another league. If you know the sound of live music, and in particular acoustic (non-amplified) instruments, you’ll find the Sopra’s do a stunning job of recreating a live musical performance.
