simple fiio e7/e9 question - Page 2

I don't know if it's a dumb question or not, since most people don't seem to have this problem.

 

My bad if I'm shifting this thread too much towards my own question 


I think you might have gotten the same batch of Fiio as mine as I had the same problem too (yesterday)!

I suspect it may be a batch of bad solders along that data/ribbon cable. It should be a simple repair job that I can do myself but I'm not risking ruining my warranty just yet.

 

Perhaps also as a little caveat to our threadstarter too: The build quality of the board is really good, but try not to bump it around too much. The 3 opamps you see there are BB OPA2134 opamps, you'll often find them in the more popular/well-regarded entry and mid-range headphone amplifiers.

I bought the E9i so that I can dock my iPhone (when i get it :) analogically when I want, and use the 3,5mm line in to connect the amp to my dacs!!


On the upside, the product is good for Red Book standard of playback, though. For me, that works as I don't listen to a lot of Chesky and other ultra high rez pieces yet (even though they sound really good).

 

The E9's dock only works with the E7, though. So do take note. biggrin.gif

Yes, but he was referring to the E9i:

Hey,

 

For those of you with only one channel sound with the E7 docked, try inserting a 3.5mm jack in and out of the rear Line-In jack of the E9 a few times. There is a switch in that jack that disables the signal from the E7 dock connector when a 3.5mm input jack is inserted. We've seen very few cases where this switch gets stuck, and inserting a 3.5mm jack in and out a couple of time fixes it.

 

Give it a try.

ARGHH....if only you had posted this earlier! I've already sent mine off for a replacement. blink.gif

Thanks for the suggestion Micca. I tried line-jack and this is what I got:

 

Sound still only comes out of the one right channel, but if I leave a cable plugged in half-way into the jack, I can hear out of both drivers. If I do a stereo test to see if the setup is working on my computer, it will play both channels, but now it shows that it's playing the right channel from both sides with no sound from the left. Basically, it sounds like it's in mono. Does that make sense? Also, I don't know if this has to do with what I tried, but I can hear background static from the amp now.

 

So far, I haven't been able to tell what exactly the DAC changes in the music. This is from playing FLAC through my K601's, so I don't think there's anything that would hinder me from hearing a difference. Of course, I'm not going to make a definitive opinion considering my situation.

 

If no other suggestions, L7?

It is mono... actually you get the signal of the one channel of the amp that works ok, to both right and left of your speakers or cans because both channels of the jack, being not all the way in, touch the one channel of the amp so they get the signal...

Out of those cases where the jack sometimes gets stuck, we had one case where it was stuck permanently.

 

So it definitely is possible that the switch is just permanently stuck.

 

Getting it replaced would be the only solution there. Sorry I don't have any other solutions.

do you buy CDs? Do you torrent FLAC files? there all 16bit/48hz (at best) anyways... only differemce is if you have a huge vinyl collection... wow "nowadays" lol. the hardware has surpassed the medians of wich media is being transfered to us... its a waist..

These look suspiciously like the legendary capxon capacitors a well known terrible brand of caps that don't last very long.

well for the lenght of time theve been on the market(whitch i know isnt very long) they havent had many reports of faulty malfunctions except for the occasional dock for the e7. there good for the quality and the price.

If I find something that I am interested in I buy cds

I already have a quite large collection of 24/96 flacs bought from hdtracks

personally speaking I don't find any reason to buy a dac (for now i don't want to go portable) 16/48 when I already have two 24/96 (not the best I admit but ok for now.. 'till the sciit bifrost starts to sell)

post #28 of 41

id be hard press to come out on top of a double blind test with 24/96 and 16/48. but i suppose id have to have the hardware capable to test it. still the main medium is limited at 16/48, i guess u can buy it better like from HDtracks but it is very uncommon, but i suppose it suits you if your willing to buy them :/

thats what im saying :(i mean i snarl at the people who say 128kbs is comparable to flac(in my mind) because to me it just isnt. and i find some difficulty discerning flac and 320(if cheap headpones) but pretty sure after the 700's and 1000's of kbs that flac is usually i dont think you could possibly tell the difference, i always based this on the fact that media hasnt been upgraded for music in over a decade and even the "big-boys" havent pushed some type of 24/96 cartridge on us yet.. its mainly the hardware manufactures trying to sell us stuff "above cd" qaulity
