Onkyo’s MSE-U33HB is an external USB Digital Audio Processor that functions somewhat like an external sound card, adding additional audio features and improving sound quality. Input devices connect to the MSE-U33HB, which itself is connected to your Mac and an external speaker system. The product carries a US$199.95 price tag and comes bundled with Peak LE and FUSE. It’s unclear whether the product is shipping now or not. Stereophile magazine recently published a brief article on the technology.
