Does anybody know if you can connect a portable media player (like my phone or ipod) to the E9 usuing the line in and the 3.5mm interconnect cable that comes with most fiio amps?
FiiO E9 is AB class amplifier as 99.9% amplifier on the market [AB works as A with a very small output currents].
Output is based on Texas Instruments TPA6102 integrated circuit, which use flying capacitor pump to generate negative voltage to avoid decoupling output capacitors - TI calls it "Direct Path". TPA6102 it's not a bad IC, and should have sufficient current for power even 32 ohm headphones with typical sensitivity, but FiiO E9 is not a good implementation of TPA6102.
My friend enjoys modified by me FiiO E9 with his AKG K702 (62 ohm) and Philips SHP9000 (32 ohm) and AKG K260 (600 ohm) and appreciates it almost as much as very decent A class amplifier, but stock FiiO E9 was truly unlistenable.
FiiO E9 has overcomplicated design [too much low quality op-amps], while FiiO E11 is (probably) only a one decent AD8397 op-amp with a volume control and chassis.
I think the E11 sounds MUCH better than the E9 WRT PRAT; to me the E9 sucks the life out of the music. What modifications did your friend make to the E9?
Or rather, what modifications did you make to your friends amplifier.
Hey all,
I don't see this covered anywhere, though the topic is definitely broached. I just got the E17 and E09 combo. It's cool, EXCEPT I have rockit speakers, which are self powered professional studio monitors with independent volume on the back of each speaker. Someone references this in the thread, but no one really confronts the painfully obvious issue that when i listen to the headphones, the speakers are still on??
Why does this unit not have a switch to kill the line/pre-out??
Do I have to return this combo? It seems hard to believe there could be such a HUGE design flaw? How are others dealing with using speakers and headphones--since there doesn't appear to be any kind of switch?
After two years or so of ownership my Fiio E9 is starting to break down. The hiss we all experience while adjusting the volume is now present much of the time the amp is turned on. Sometimes I can fiddle with the volume pot to make it stop but as of now I am looking for a new headphone amp. I was impressed with the quality of the amp for the price when I bought it but I cannot recommend it in terms of long term durability.
That's what happens to cheap Chinese crap after a just few years. Next time, it will serve you well to save up a little more and buy something decent, perhaps made by a real person (maybe in this country) who actually cares about the buyer.
So says the guy with all that "Chinese built crap" in his profile.
Sounds like a bit of racism to me.
Maybe you should sell your Chinese imac and find a computer 100% built inside the USA. Good luck with that! It's impossible!

Can you plug the E9 into the computer, then plug your headphone into the amp?
