Got a chance to compare AK SP1000 (2 ohm SE), AK Kann Cube (1.2 ohm SE) and Sony NW-WM1A (unknown OI on SE and all sound effects turned off) on SE operation ONLY since I don't have any balanced cables, and I want to make the comparison with the SE only DAP such as my iPod Touch 7G/6G. All impressions are compared to iPod Touch 7G. One thing I discovered is that I now understand how some say balanced cable and balanced operation have wider soundstage, better imaging, etc. than SE. My ears tell me that the iPod Touch 7G provides much wider soundstage and more space between instruments than WM1A and the Kann Cube on SE operation. It was a tough call for the SP1000 (SE only) since it was similar to iPod Touch 7G/6G in soundstage but cleaner sounding overall thanks to more sophisticated audio circuitry of the SP1000.
BTW, to my ears, the iPod Touch 7G definitely provides a very holographic out of the head soundstage width and instrument placement with Andromeda now that I had it compared to SE outputs of some popular DAPs out there.
Conclusion: If you buy a balanced DAP, always use it with balanced cables to maximize your DAP potential.
I also briefly compared the Andromeda with Z1R and definitely preferred the Andromeda's tonality over Z1R's slightly better technicalities.
