Check my post here guys. It will help you extending your DX100 / R10's battery life!
Thanks, will try this out with my DX100. not sure how it would affect the DX100 since the DX100 uses 8.4v as its working voltage
will report after testing this out
The DX100 is better and that would be a very good price for it. It is larger of course but has an airy sound yet has plenty of power for most phones.
I definitely agree that the DX100 is much better with sound quality than the DX50. The DX90 would be closer to the DX100 but still not quite as good. But there's tradeoffs. DX100 is more of a brick and (at least for me) doesn't have the same battery life as the DX90 (which has the benefit of replaceable batteries). So for pure sound quality the DX100 would be the way to go but if size and battery life are issues for you then I think the DX90 is a good compromise.
To be honest, I've never been a big fan of the sound straight out of the Clips. Could be a different story with an external amp but I've never heard a Clip that way. I feel that any of the common DAPs now available - X3, X5, DX50, DX90, DX100, etc. - would be an improvement in sound quality over the Clip, though others may feel differently. The DX100, though, is certainly much better! I don't think there's any comparison.
Yeah. DX100 sounds very full compared to Sanza.
IEM sounds better on DX100 as well. In terms of sound quality, DX100 is ranked among top 5 portable DAPs in the world.
