it is depend on the impedance and the sensitivity of headphone, low impedance need high current and hight impedance need high voltage! or is about power !
 
in fact, even some IEM will benefit from a amp because the amp can work in the best situation and have enough headroom for the music!
 
for example, if you are only drive in city, you don't need a 5L engine in most time, but it can help you in occasion that you want fast acceleration！

if I'm running with sensitive cans, am I need to upgrade to E9 to improve SQ from E7?
 
note that using E7 as dac+amp combo, my comfortable volume is 2-10, and max volume I can take is 20. (set bass boost level 1)
 
I love the digital volume in E7, it's so good for low listening volume (which is I do every morning). How about volume pot at E9?

If you just care about the SQ, I think it is unnecessary to upgrade to E9, in fact, E9 is not a upgrade model of E7, it is different usage! if you have speakers or other device, especially big cans, E9 will suitable
 
for you, and you can get a USB/DAC + high power output amplifier, but don't need to pay extra money for the DAC because you already have a E7!

Sure, you can use a LOD connect the line out of ipod to the 3.5mm input jack of E9, and connect the 3.5mm output to the input of your audioengine a5!  and usd the volume control of E9 to control the system
 
volume! or connect the RCA output of E9 to audioengine a5 and control the system volume by the volume control knob in speaker! personally I think first solution will be better!

ahm...thanks fellows!

 

[ajreynol]

just checking in.
 
looking forward to it.

To our friend and user:
 
            Since E9 is not a normal desktop amplifier, so it is a little hard to explain all the feature, someone say one picture better than a thousand word! so I put the diagram of E9 in here! it can let you know
 
how it work!

hope to see part two sometimes this week =D

My question is like the one above except I have a Denon D2000.  I listen with the E7 set at 20.  25 is really loud to me.  Will the E9 help the Denon bring out even more detail in my music or is it only for making the volume louder?
 
Also I have a HD-A1 HD DVD player and they are supposed to be excellent cd players, can I use a RCA to 3.5mm cable to connect directly  to the E7 or E9? Will the E7 DAC be used connected this way or will the A1 provide the DACs?  Thanks
 
I'm new to the headphone world and by reading this forum for the past couple of weeks I decided to go with a Denon D2000 and Fiio E7 out of my iMac and iPad.  The sound is nothing short of AMAZING.  It feels like i'm hearing my cd collection for the first time.  I can't stop listening!!!

You can just connect your HD-A1 to E9 with a RCA-3.5mm cable directly! at the same time, E7 will not work as a DAC because it can only decode the USB digital audio stream!
 
BTW,  sometime the SQ is not only about volume, but you don't need to pay more if you already satisfy with E7+D2000! cheer!

I am definitely pleased with the sound I'm getting with the E7 & D2000 combo.  Thanks for your reply!

I'm seriously thinking about going for the E7+E9 combination as at the moment I obviously have neither. I wish to get a decent DAC and a decent headphone amp without spending astronomical amounts of money. I was previously heavily in favour of the ASUS Xonar Essence line of product but now that the Fiio combination has come to my attention I must admit that the prospect of portability is a nice one....unless the Essence DAC kills the E7 DAC. Or is it the other way around in this case that the hardware E7+E9 is better than the Xonar Essence ? I'm probably asking the wrong question at the wrong time and it's highly likely that by the time someone answers this I'll already have two lovely Fiio products. Well hopefully, as Fiio would be my first brand for audio products of this nature.
 
Wow only just noticed, I'm over 100 posts. Nice.

I've thought about maybe buying this as my first amp, but I have a Zune HD.  I've heard that using the headphone out on the Zune directly into the amp would have worse sound quality because the sound is already amped.  Is this true?  And if it is, how else can I connect the Zune to the amp?
