Thanks a tone, guys. Would you consider the sound of the Galaxy S 4.0 + Voodoo + Power Amp superior to a Sony A865? I love the sound of this player but they cost almost the same so I wouldn't like to make a big mistake. I still have 10 days to return the A865, so time enough to test the Galaxy S 4.0 + Voodoo though.
One thing: Sony doesn't support FLAC or any lossless audio codecs (except for WAV, which guzzles down memory like there's no tomorrow), so you're stuck with lossy music. As to the SQ, I cannot comment as I've never heard that particular model.
Also, the UI looks to be a bit dated, not to mention the fact that it uses a resistive screen; navigating seems to be a bit difficult?
