BluHifi takes another stab at crowdfunding its BluAmp Bluetooth amplifier

Earlier in the year, Utah's Aaron Myer launched a Kickstarter campaign to get his BluAmp Bluetooth 50-watt amplifier into the hands of wireless music lovers. Unfortunately, the campaign didn't reach its funding target, but Myer pushed on regardless. The newly revamped BluAmp 50 has been joined by a less powerful sibling, the BluAmp 20, and Myer has hit Kickstarter for a second timeoth flavors of the BluAmp Bluetooth amplifier feature Bluetooth 4.0 with the aptX audio codec, but will support streaming from devices with earlier versions of the wireless technology. The amps can auto-detect when a paired music source is within range and are said to be compatible with any brand of Bluetooth speakers (though they can be cabled up to non-wireless speakers, too). Output volume can be controlled using the dial on the front of the BluAmps, or wirelessly via the source device.

Each unit is powered by a 120 - 240 V external supply, has a 3.5 mm line-in jack for playback from a wired source, and boasts less than 0.03 percent total harmonic distortion and noise at 10 W. The BluAmp 20 is built around a 20-watt RMS per channel Class-T amplifier, and the BluAmp 50 has been treated to a 50-watt per channel Class-D digital amplifier. The latter also gains stereo MEMS microphones for speakerphone capabilities, EQ tweaking and track control on the unit itself, and a subwoofer RCA output to cater for some extra low end thunder when hooked up to a powered subwoofer.
