Could someone please educate me why one would need the E09K amplifier with the E17 amplifier? Are there headphones that the E17 alone can not power?

The 17 is portable about the size of an ipod. The 09 is a desk top model about 4"by 8" by 3" high. The 09 is a charging station for the 17 (but it can be charged independently. I use both: one as a desk top amplifier and one as a portable amplifier on the go. You don't NEED both but they are very versatile together.

If you are using very expensive hard to drive headphones you need a desktop amp with more power so the e09K will be required

You need a cabinet, because the amp has to have an ohm load on it. If you want to just use headphones, you need a headphone amp.

Same question , but there are conflicting answers so I'm going to ask again with a disclaimer...Will the headphones work AT ALL if the battery is dead? I do understand that the noise cancelling functionality, and other advanced acoustics require power - but isn't it programmed to play basic audio if there is no charge? It's kinda crazy that a $10 pair of earphones can work without power buy a $350 device is useless without any power. Again, I'm not asking about full functionality - I need to know whether "bare-bones" audio functionality will work without a charge???

I don't know but I'm using the Fiio E17 and it does a fine job with the HE 400's.In my opinion you definitely need an amp and the FIIO E17 has bass control which makes all the difference. I just want to say that the more I listen to these headphones the more I appreciate them.

The amp does not add rumble to the source. It seems to just exacerbate the rumble if it is already present, especially if the output is through cheaper speakers or headphones. The quality of the source and original recording seems to have a significant impact on the output. For the most part, I must say that the E11 amp sounds great, and worth every penny. Some of the pricier amps have more accurate EQ's that include more mid-range control. I will probably be giving the E12 a shot in the near future, and possibly the E07K DAC later on. They both have a higher degree of EQ control (so they say). The amp does not add rumble to the source.

The E7 will be installed on your computer as a new sound device. Because of that, you have the option of choosing the output device for windows. If you select the E7 you will hear sound out of the headphones; if you select the default sound card, you will hear sound out of your computer speakers. Some programs give you the ability to select the output device for only that program. (Skype is an example.)

I use my P7 with an iphone 4 and the FiiO E11. Without the Amp is fine but I will say with my FiiO E11, the sound is better (not as loud) and the Bass is perfect and not overpowering. I did not expect this, like Johnny wrote, "They are very low impedance @ 22ohms." I expected the bass to increase but the sound is better as well.

Thanks for the replies. Will keep it in mind when I am ready to buy a headphone amp.

The only reason you would need an amp is if your original source is limited. Otherwise don't bother. But if you really feel the need here is one source discussion I found. http://www.head-fi.org/t/635772/need-help-should-i-get-a-headphone-amp-with-v-moda-m-100

Yes. This is just an amp. It combines well with the fiio e17, it docks on it and acts as a dac, then you have the option to either bypass the e17 and amp with the 9k or amp with both

I was puzzled by the "yes" answer. My model does not have and sort/size of headphone jack. I have usually seen headphone jacks on receivers, pre-amps, and amplifiers, but not on source equipment...

sorry I'm not to tech savvy. I had a friend help and I didn't know much of what was going on. I do have a separate amp, which is an inuke nu1000sp, made by a behringer. I have 3 total, 1 each on three chairs. they do work really good, especially compared to the higher price ones. if I can find more info I will let you know.

I have dt990 250ohm, and UDAC2 works just fine. I've never tried dt770, but I think it's similar. I only have to turn the volume half way and it sounds great to me. I'm not a audiophile, but... just my two cents.

Coincidentally, my local music store had a headphone testing/"sale"(10%, covered tax lol) over the weekend. I own the anniversary ed and , although i was there to pick up my guitar cabinet, I tried out the white K702, along with other headphones. The amplifier used was a different form factor than my own(they had a solid state and i use tube), but the noticeable differences, regardless, where bass and comfort. the Annies performed better in these areas. There are claims that trebles are also improved, more clear and tight, but i would have needed to hear both headphones in the same setup to have noticed.

I owned 429s Sennheisers i got same problem the amp makes the volume louder on all 400 line Sennheisers i think,also might wanna think about getting fiio e11 i heard it goes louder than e6 but cant be used while charging like the e6 can.Makes Sennheisers sound awesome.

I'd start by just plugging right into your receiver and see how you like the sound. some receivers have decent headphone amps, others have horrid ones. I don't know your model, but my Yamaha has the horrid type unfortunately. if you find you don't like the sound, be it too muffled, thin, or lifeless, then add an amp. there are many you can add. I run mine on a schiit vali and I love the pairing. the schiit magni is a good amp as well, more versatile than the vali. there is the jds labs o2 amp, and many many more. you'll need a line out from your receiver though. I was shocked to learn mine did not have any line level outs, so I had to run an optical out to an optical dac, and connect my headphone amp to the dac.

Not at all. The Fiio functions as a stand alone headphone amplifier. However, if you choose to combo it with the Fiio E17, you will have a nice, functional DAC/AMP.
