I think the E17 even when not on USB charging mode draws enough power to run itself even when not charging (makes sense to do it that way if you have it docked in an E9, but I'm guessing the CCK USB port isn't putting out 500milliamps as per the USB specs)


Might be worth a try when I find the time - and yes, the iPad with CCK only allows for < 150 mA of current, quite a bit lower than the standard 500 mA USB spec. I still like the idea of a proper cable and/or battery powered USB hub, but something nice and clean that would still make the iPad a pretty decent 'portable' music player (when equipped with FLAC Player or VLC and loaded with well ripped FLAC content).

My E17 turned up a couple of weeks ago and I've listened to it a fair bit since then.

 

Using the LOD from the iPhone 4S to the E17 and then Beyer DT1350's, I can't discern any difference between the E17 and the iPhone 4S's normal headphone out.

 

Running the E17 from USB at 24bit, 96k and comparing it to the AUNE driven via digital (at 96k/24bit) the E17 seems to be a little brighter when listening with Grado SR325is's, though not really any noticeable difference with the DT1350's.

 

Listening to the E17 driven by USB at 24bit/96k and comparing it to the iPhone 4S there is more of a discernible difference, but again, nothing too huge.

 

Maybe my ears are just crap, but I'm not seeing any significant difference with the E17 from the iPhone 4S's built in DAC, especially when driven by line-level analog input.

 

I can't see my carrying the E17 round with me rather than just saving the bulk and using the DT1350's direct from the iPhone 4S. There's just not enough difference to make it worthwhile (if any!)

 

Anyone else found the same?

Ditto for me.  I have no use for the E17 as a portable amp from my iPhone4 or my iPod with either the Senn HD25's or vModa M-80's.  Where the E17 shines is with my Mac Mini or MacBook Air as a dac/amp.. amazing.

If only we could get at the digital stream from the iPhone/iPod and use the E17 dac.. that would be amazing!

I hear a difference with and without the E17 on my 4S. A lot of it falls into soundstage, but the overall sound is slightly different too. I find the 4S alone a little bit warmer. I can do with either setup, though I do prefer the sound out of the e17.

Everyone's opinion on how much difference or what ot listen to is different. If it doesn't work then it doesn't work :) hey sometimes it's even better...it's annoying if you hear every single thing wrong with your equipment.

I use my E17 with my ipod mainly for the different (small change) sonically..but mainly for EQ..nothing else and to drive it on my oldies songs...and yes..from computer...with WM8740. difference to me is huge.

I find it warmer also, not necessarily good audiophile warmer, but good consumer sound warmer. I find using the E17 with the ipod touch 2G to be a bit colder and more transparent at times, but when using the WM8740 DAC..it changes. i have a 4S but i don't use it with E17. you have to turn on airplane mode on my 4S or else EMI sneaks in (AT&T in HSPDA area)...over Faux-G.

My thoughts exactly. Having the e17 is a change, but for the better. Though I don't have a data plan so I probably don't get nearly as much EMI... not absent though :<

....tell me sir. how you got a 4S with no data plan? beyersmile.png and there is not a loud EMI with mine on ATT with HSPDA region...but a good volume of it. tested it once while out so wifi and bluetooth was not enabled, only Faux G and no other known wireless emiter or receiver. Turning on Airplane mode quickly cancelled the EMI....but....it's my phone.....i can't exactly just leave it like that and all my songs are on my ipod

such a good sexy looking combo :) I just took a pic of my 4S and E17..i dind't actualy use it as I didn't have any music on it and I didn't care for streaming(even if the maximum support of airplay is uncompressed CD quality)

 

I took the pic with another 4S I had on hand, the one in the pic is mine :)

 

IT is for the better but many can't "hear" the changes and I understand. Everyone is different. The changes aren't huge for me portably. the changes are like those thing that always annoy you. like that itch behind your back and with the E17 it takes most of that itch away(song dependant) i Find that sometimes I just want consumer sound though :/

Well, they sell unlocked phones now. Actually since a few months ago? I guess that means you can just buy one for full price and do whatever you want with it, with a data plan or not.

In my case, my dad got one as his new cellphone, and he let me have it (thanks dad!). I cut my sim card up and here I am using it w/o data plan.

I can't afford paying for data every month... especially being in this hobby!

ok the first one i ruled out since....that's way to expensive and someone willing to pay that much would probably have data

 

i ruled out the second one as I've never known someone so generous(even in family)...i salute your father sir.

To anyone who wants more information on the Senn HD 600 and e17 combo I can post some impressions, but I'm to lazy unless asked. 

 

But to be concise: It makes a world of a difference for volume output on the ipod, and really brings out the lower end, and soundstage. The sound is overall much fuller and clearer.

:)

And just for clarifications, my family is anything but wealthy. And yeah, pretty surprising he'd let me have it.
 

 

Also, found it interesting that I was driving Beyer 250ohms (770 and 880) in the store at 0 gain and ~28 on volume setting.

Guess these really can push tougher cans, which is never a bad thing!

 

And why have I yet to try docking on my bro's E9, I have no idea.

all you need to get for that EMI is a sound attenuator / impedance adaptor thing.  you can get one with in-line volume control that's like 3 inches long at Radioshack.  I basically converted my triplefi 10's into a much higher impedance IEM with it.  I read that it changes the EQ a little, but most won't find that to be a bad thing.  Even more than ever I feel like the TF10 with the airplane attenuator sounds like the DT880 250s...  and I pretty much have both at the exact same volume and amp settings, too.  They get driven near the same volume as my DT880s and it's easier to drive at lower volume.

I'd be interested to know which track(s) and passages you can hear a difference on - just for my own interest really. It'd be interesting to know if either "my ears just ain't that good" or whether it's a case of training my ear to be able to hear the difference...

 

I know there's a certain element of that involved...

it's very hard to do something like that. the closest, easiest test that is easily deployable and done that deals with some aspects of this would be something like an 320kbps MP3 or AAC vs Lossless test using foobar ABX to see if you can hear it. Many get 50% meaning ...a guess as in many head fi'ers can't tell the diff, if it's that then I would recommend doing an 128kbps vs 320kbps or something lesser quality vs something higher quality, and make it even more drastic like 128kbps vs lossless if you still can't hear. I did an 320 kbps vs lossless test and expected to get a 50% guessing rate..i actually got 1% amazing basshead.gif and felt pretty proud. if you want insturctions on how to do this properly then just ask me,
