  At low gain with all my usual (C)IEMs it hisses. I don't recommend it for sensitive IEMs at all.

power it with a separate usb charger rather than a computer usb port, see if that helps.

yeah well, what can I say. It's hiss all over on my customs. Even the old E11 doesn't hiss this much

It hisses when not charging. But yes, charging it makes it even worse

 

[mindbomb]

bass boost off as well? what is your source?

Definitely think you may have gotten a faulty unit. Hopefully you can RMA it.

it cannot hiss more than the E11. The output inpedance of the E11k is higher than the E11.

OI rating doesn't really have much to do with how much hiss an earphone will pick up in an amp. Hiss has more to do with thermal noise generated by the circuitry, which is usually measured in microvolts.

JamesFIIO did say they made this for sensitive IEMs, so it could really be a faulty unit.

the FiiO E11k is of such good value i have to have it, even though i have quite a few other amps and DACs lying around already. Its like one of those cheap but extreme value for the price gear u really want to have even though u already have much better stuff.

I just can't get over the impractical shape. Neither can Headfonia it seems http://www.headfonia.com/fiio-e11k-new-budget-king/

 

[TripBitShooter]

sigh... such a mistake in such a great product

 

[georgelai57]

Maybe the shape is meant to fit a whiskey flask

FiiO can probably (very cheaply) make a piece of injection-molded rubber that is flat on one side (to interface with a DAP/smartphone, etc.), and curved on the other, matching the E11K. That'll go a long way, IMHO.

Mine is "in transit" (tomorrow

 ),  but I assume it ships with the rubber feet / stickers the that came with the E11.  I just plan on attaching them along the outer edges and it should both lie flat on my desk and rubber-band nicely to the back of my iPod Classic 5.5.  I did this with E11 so it would't scratch either surface and provides a little distance between the components.
