Galaxy S3 phone and external DAC

The Graham Slee Bitzie DAC works with the Galaxy S3 - the sound quality is excellent and I recommend it highly

You need a cable that is micro USB (out from S3) to USB 'B' type (into Bitzie DAC). The Bitzie has a phono 'Y' output adaptor included in the packaging so you can connect to a main system via phono interconnects

In several countries there is a loan scheme to borrow the Bitzie before purchase (UK, Europe, USA, Australia etc)

It also acts as very high quality USB DAC between a computer (PC or MAC) and main system. There is a high quality USB 'B' - 'A' cable for this purpose which can be ordered as a standard option

Trying to improve mp3 is really a hopeless cause...
However,the best way to get files from your phone to the stereo is with a bluetooth device. A dvd player like Oppo will work and I'm sure there is a cheaper option out there.

So I ordered this about 2 weeks ago, then we left on vacation. I got back today and picked up our mail and there it was in a little bubble pack. Very tiny. No instructions. I plugged it into the phone's USB and then into the jack on my upstairs system and ...

Wow - there's the BASS, man. Much better detail and a soundstage and transparency than the standard earphone jack on the phone. I had to turn it down because it puts out a lot more gain. I'm also guessing that it will improve a bit as it breaks in but it does indeed sound damn great right now after about 1/2 hour.

No idea how it might compare to a real DAC on the downstairs (main) system - maybe some day in the future, but this is a no brainer for $30. If you have an Android phone and want to play the music on it then seriously just buy this.
