I've bought a new E7 to pair with my Sansa clip. But it seems not to improve the power of output Without E7, I set the volume at 80% to be enough to hear. But with E7, I still must set volume at about 75 ~ 78% (with the maximum volume in E7) to be enough. I'm not deaf, so does my E7 have any problems? Beside that, Fiio has recommended their product to be set at 20 volume by default (

You should have set it the other way, max on clip and use the E7 to control volume. E7 volume control is not fully linear, so it varies the gain from -60dB or so to +5dB. Hence, 0dB (no gain) is right around 80% on E7. Setting max volume on clip also help getting better dynamic too.

I am actually wondering if he plugged the E7 correctly.

I don't think I did the wrong way AUX input of the E7 is the output of the Clip, and the headphone is plugged in at the top of the E7. I think it's hard to handle with them incorrectly

Precious information! I'll give it a try with hopeful

It will be more easy to find the different between the headphone out and the headphone out when connect E7 to the usb port of PC! My opinion is that headphone amp may not suitable for anyone because some headphone can be
 
drive quite well by DAP! and sometime the SQ different is very small, that is why most people are satisfy with the original earphone of Apple!

Hmm, does sound like a mismatch between the Clip and E7.
 
I am quite surprised at this, I can't turn the volume higher than 25... but then I am using an iPod with an LOD.

Depend on my experience! sound quality depend on age, civilization! and other factor, so there are not a standard for good sound!
 
and that is why there are so many kinds of HiFi audio , and it is the fun of HiFi! in my opinion, Good sound quality just means you are happy
 
with the music! when I was young, I will enjoy some heavy bass, but I tend to more balance sound!
 
So, what we try to do is make some good quality products with neutral sound, them you can enjoy different music but not only suitable
 
for one kind of music!

My experience with the e7:
-Bought one on ebay from a trusted seller, and it only went one notch louder than my e5 on MAX volume.
-Sent it back thinking it was faulty
-Got one from Mark (demoed it), the one who created this thread, had the same experience.
 
In other words the e7 has to be driven by certain things.
ie. My samsung galaxy s cannot drive it.
Meaning I was on volume 50-60 all the time, whilst being told online and from mark that over 25 hurts your ears...

I agree with this. In Viet Nam, some guys who used E7 too have confirmed this thing. In some case like Ipods, the volume (also the sound quality) is effective. In some others, it is not. The E7 seems not work to all kinds of device. Am I saying anything wrong, Feiao?

I just purchased an E7, hopefully Ill get it in the next few days and give it a good test run with the sansa clip+ and let people know how well it performs

There are some DAPs only have small output level, and the gain of E7 is only 5dB ( old version is 3.5dB).  in this case, the output level is not enough to drive the E7 to the max power, so it is about the gain but not the output power!
 
Also, volume is not equal power, We had test some famous amp, which have only small output power, even less than iPod! but it can color the SQ! and also be a good amp to some people! there are not an absolute perfect which can satify everyone! and that is why we
 
develop E11, it have 10dB gain and higher power, it can be suitable for almost all DAP which may just have very small output level!

Exactly, the gain of E7 is only about 3.5dB ~ 5dB. How can I find out which version (new or old) my E7 currently be?

Awaiting for your report...

 

[JamesFiiO]

Depend on the sales, current version should be 5 dB version!

I am really, really impressed by the output of the Fiio E7. It actually managed to run the HD650 (though I have to crank the volume up to 40) quite nicely. It could do better, but as a portable amp, that's pretty damn impressive.

got the e7+e9 combo and no complaints so far! my only wish is an upgraded/premium version of an e7 that supports 24/96 in the future!

 

[Jack C]

Based on the boatload of new product release info that FiiO has dropped onto Head-Fi I would wager that a higher end DAC/AMP with 24/96 or even 192kbps support with the FiiO dock capability is probably in the pipeline somewhere. Disclaimer: this is purely speculation on my part.

It is not impossible, but it will need a better USB receiver chip to do it. Typical USB receiver only do 16/44.1 due to limitation on USB Spec, and anything higher generally are more costly.  I guess it is the question on finding balance between cost and price.
