This are softwares I've been tested,
- Windows Media Player 11
- Songbird 1.0.0
- Foobar2000 v0.9.6
- Winamp 5.541
With laptop and USBPre interface from Sound Devices and for shorten the list, let's say highend audio system.
IMO, Winamp is the best sounding. Better staging, imaging, depth, ambience, layer, etc...
If you want to learn about what is imaging, staging, etc .. google for EMMA and IASCA guide/rules.
