On spec, both should be relatively easy to drive. However, just because it is easy to drive doesn't means it won't improve upon amping. As I said before, some headphone benefit from big current reserve, and you can't tell that from spec. You will have to try it out to find out. Some amp also have coloration that might be favored by the user, like the bass boost in E3 and E5.

I did, and still own it. With OPA2134, this little cmoy actually sounds really good.

go for viper paca!

viper bttr but for rm300 n not for portable..i wonder how zero vs viper?

theres a lot of review..at head fi..
but beware..i dont think ur ie8 is safe after that

if u r lazy u will be left behind     

im not Paca la.. im his rumate.. just share computer... we at USM now

My Fiio E5 doesn't seem to improve the sound quality by much though..However, when I push the bass control button to the middle, instead to either side, the sound really does improve a lot..

I guess it's my own impression only? If anyone tries it and feels it's true, please tell me!

This has been posted on Head-Fi for a few days now, but I guess I post it here as well.
-----------------------
I just received an email from our friends over at FiiO (Thanks, James) with more information regarding their new amps, and this time I get the go-ahead to share them with all of you.

Here is the rendering of the new FiiO E1, an in-line amp for iPod. No production shot yet since FiiO has yet to make the final production model. It utilizes the power supply and line-out signal from iPod dock connection and incorporate an digital volume control as a remote. You can think of it as the union of E5 + LOD. The ETA is around end of August / early September. Not sure about the price yet.



Here are some pre-production shot of FiiO E7, FiiO upcoming USB DAC + AMP, note that this is not the final look (but it probably won't be too far off). Battery life is expected to be >100hrs, The 5 sides of the housing are CNC'ed aluminum (with harden acrylic on the last). ETA is estimated at December (likely around X'mas like the E5). There will be a dock planned for later release, which will enable remote control function and two line-out (one variable and one not) in case you want to connect it to speaker or use the DAC function only. E7 will have a special dock connector for docking and there is also plan for further accessories development, which will allow connection to desktop amp, mini Hi-Fi set, speaker and such. E7's price is estimated to be lower than US$100.









So, any thing else you want to know?

well,just wanna share.im using klipsch custom 3 and pairing with E1 doesnt give any changes .as far as my ear can listen,there is only little,very little improvement.while pairing with e3 is like taking my iem another level higher.maybe this is due to compatibility. maybe my klipsch doesn't sync well with E1 but do great with E3.now itchy to try E5

d E5 is a reali low noise amp, unless ur source is noisy.

Mine is the complete opposite, no hissing regardless what PMP i use.

EXCEPT the ipod shuffle 2nd gen. Others like Sansa Clip, Cowon & Sony X-Series no problem...
