“Better still, as ST told it, the B1 offers considerably better-than-average sound, with its “natural harmonics, an extended top end, and crisp, clean transients. I have not yet heard a Bluetooth receiver that tops the B1. Consider this a rave.” Connected between the L/R inputs of Kal’s Bryston 9B-SST power amp and the L/R outputs of his Anthem Statement D2 processor, the W3 lacked high-frequency sparkle and midrange detail while sounding “surprisingly okay.” The W3′s sonic compromises were much less noticeable when it was used for the surround and/or bass channels.” —— stereophile.com
