Sound Field? Looks like there's a loy in there fir the money. I was checking this one out about a year ago and never pulled the trigger.
I got something else to play with instead that turned out well. If an amp is good it should actually improve the line out from a DAP into a more demanding load. Basically, the added control and dynamics are a greater positive if the amp is clean enough to not cause other issues. E11 is not one of those, for me either. Line out will vary. Things like the DX100 ot Studio would be hard to improve from their HP out but most DAPs can be with the right amp.

I'm achieving best results from HM-601 line out atm. Nice, smooth, plenty of power on tap, this amp also improves stereo greatly on all the sources I've tried, stage depth is also noteworthy. I spent three hours listening last night and my initial impressions haven't changed, if anything I'm liking it even more. Size, power and most of SQ. I can safely say this surpasses my old E11 and can't wait to get some impressions in to confirm that. Cleaner, smoother, everything blends nicely. And we're creeping up past 10 hours so far, I'll be keeping a tab on the claimed 80 hours battery life.
