Hosa Technology's Cue 5 is the first all-digital monitoring system designed specifically for the desktop recordist. The Cue 5 system's Binary Drive extends the user's all-digital signal path to include the onboard speaker amplification—delivering every audio detail to the 5.25-inch LF transducer and 1.5-inch silk-dome tweeters with zero intermodulation distortion and a nominal noise floor. The Cue 5 system accepts 24-bit/96 kHz signals directly via optical or coaxial S/PDIF inputs. Comes with control software for Macintosh and PC.

From the Hosa Site:
