Annexing the Hiface Two from the Squeezebox Touch’s power supply so that only audio data was permitted thoroughfare demanded a different USB cable.
Michael Parin from Adelaide’s Elijah Audio had sent me his BPM “Battery Powered Module” (US$105). It segregates the Hiface’s data and power feeds: the main connector hooks into your audio device (Squeezebox Touch) and the tail connects to your 5V power supply (
KingRex UPower).
The take-away result is the same on the Squeezebox Touch as it is on both MacBook and MacMini: the UPower and BPM take the sting out of the Hiface’s top-end. A hint of upper-frequency etch is soothed away; the sound is put poolside with a cocktail. Unfortunately, round back the Elijah Audio cable pushes hard against the Squeezebox’s power umbilical. Another reason to move to Apple hardware.
For this reviewer, the Logitech device is off to the subs bench.
