When my E12A amp is charging I will listen to my A17 sans amp and the soundstage is fairly decent. But when running it through my E12A I really notice limitations in the A17's soundstage as it is definitely wider and deeper with the E12A. I could get by without an amp but I would miss the obviously bigger soundstage and the additional power when needed.
I will say this the soundstage is certainly better than the Fiio DAP's but still not great If your experience is limited to say Sony A10 series and Fiio DAP's without amps then your idea of a big sound stage may be quite narrow. But if you compare it to a wider range of DAP's that is when you will really appreciate the A10 series soundstage for what it is.
Just a question, can the amp E12A eliminate the background hiss of Sony's DAP or we need a separate external DAC for the hiss to be eliminated?
it's a very safe bet. the E12A is known to have a very clean background itself. and using the sony maxed out(line out, or headphone out way loud), the gap between music signal and hiss will increase enough not to be an audible concern anymore.
