Amazing!!!! - Douglas Robbins
I used to carry my phone in my pocket while listening to my earphones while I cleaned the kitchen. Occasionally I would even drop my phone when bending over. I love my BluAmp because I don't have to carry my phone in my pocket or have my earphones in my ears and I get to enjoy controlling my music from my phone while enjoying much better sound quality. - Elisa Johnson
What is better than listening to great music? Listening to great music with friends and without the fuss of headphones and wires. The BluAmp is the ultimate accessory for any iPod, music player or phone - a true high-fidelity stereo amplifier that plays audio from any Bluetooth source. You can control the music and the volume from your phone or music player.
The BluAmp lets you enjoy the music from your iPod, phone or music player with full range high fidelity speakers - with true stereo separation and a rich soundstage. The BluAmp is different than the typical iPod dock, because the stereo speakers can be placed anywhere for optimum stereo imaging, instead of the glorified mono sound that comes out of most docks.
Use it in the bedroom to play music while you wind down, and it will power down when you stop the music from your phone. Use it in the kitchen for background music while cooking, cleaning or just hanging out. Use it in the office to play high fidelity music and movies from your computer music library, Pandora or Internet radio.
Use it with outdoor speakers in the back yard for parties or just to relax. Use it with your own music library, or Pandora from your phone. Use it while gaming and get rid of those annoying wires.
The BluAmp is a 50 watt/channel stereo digital amplifier with a built-in Bluetooth 4.0 receiver for CD quality audio from any Bluetooth 4.0 phone or iPod. The BluAmp is compatible with earlier versions of Bluetooth too. The BluAmp was designed to be small and efficient, with lots of power for the highest quality audio. The BluAmp can be used with any speakers, large or small and it is 4 ohm stable. The main knob controls the amplifier volume, as well as bass, treble and track forward and reverse.
The BluAmp can be used with any audio device that supports Bluetooth headphones. This includes the iPhone, some iPods, the iPad, most smartphones including Android and Blackberry, and most computers. On the back of the Bluamp is a 3.5mm audio input jack and cable included that allows the BluAmp to play music from a phone, TV or music player that doesn't have Bluetooth. Connect it to your television headphone out and you can control the volume from your TV remote.
The BluHifi speakers are the perfect match for the BluAmp. These speakers are small in stature but pack a punch. Solid bass and crisp highs make them the ideal driver for all types of music. The speakers are only 11 inches high, and incorporate a 5 inch long throw woofer and a dome tweeter. The speakers are available in a beautiful piano black finish.
The BluAmp prototype is complete, and the Bluetooth receiver and amplifier are working well and sound great. The mechanical design is complete and ready for production. The preamplifier board design is complete and prototypes have been tested and are working well. A minor board revision is required before production can begin.
The speaker development is complete and production ready.
I need kickstarter funding to complete agency approvals and the final preamplifier board revision. I will also need to fund an initial production order of the BluAmp and speakers.
The BluHifi T-shirts are high quality shirts with the logo in two styles and sizes from S to XL.
The Bluetooth USB dongle is a class 1 Bluetooth 4.0 USB module that allows high quality audio streaming from a PC to the BluAmp. The dongle is compatible with Windows XP, Vista, 7 and 8.

Risks and challenges
The BluAmp project has risks. Most of the pieces have come together nicely. Here is where the project currently stands:
The BluAmp pre-production unit is complete and has been tested. The power supply and digital amplifier work well and sound great, and the chassis is ready for production. The preamplifier board has been tested and works well, but needs firmware work and some minor hardware changes including another board spin for production.
The BluHifi speakers are ready for production.
1. The preamp board needs some minor hardware changes for production, including some parts changes and a few traces need to be moved. Every board spin has risk and potential for additional delays.
2. The preamp board firmware is only about 70% complete. The firmware complexity is low, so this should not be a problem.
3. Once in production, product delivery can be delayed by parts availability and scheduling problems. We have identified second source suppliers for the critical components and believe we have adequate contingency plans.
Most iPod docks aren't wireless, so you have to get up or use the remote to change the music.The BluAmp uses the wireless capabilities of your phone or iPod to play the music, so your BluAmp and speakers can be across the room, while your cover art and volume and play controls are in your hand.
I built the BluAmp because I couldn't find anything on the market to play my music on traditional stereo speakers. There are lots of docks on the market, and some even have bluetooth, but they all pack both speakers into one box. The result is compromised sound - it is impossible to have really good stereo separation and stereo imaging when the speakers are sharing the same box.
The other reason for building the amp as a separate unit, is speakers have a huge effect on the sound. the BluAmp allows you to use any brand of speakers you want, so you get the sound you want. The BluHifi speakers sound fantastic, and I can't find anything on the market that compares to the sound quality of the BluAmp with the BluHifi speakers, even at twice the price. Of course, you can spend thousands on even better speakers and the BluAmp will run those too.
Yes, the power supply in the BluAmp will handle 230 Volt and 50 Hz power. The BluAmp comes with a C8 style detachable U.S. power cord, but it can be used in other countries by changing the cord.
Yes, the BluAmp includes the apt-X codec for high fidelity sound over Bluetooth. The Bluetooth 4.0 receiver in the BluAmp is fully compliant with the Bluetooth 4.0 spec, and is also backward compatible with Bluetooth 2.0/2.1+ devices.
