  only a very soft power on pop.  helps if you turn it on gently

That I'm aware of. This was constant popping with static that wasn't stopping.

I have not experienced this. Defective unit?

^ I appreciate the response. It probably is.

I never went beyond 5.5

Yes, there is noise with no audio playing but we won't notice it while playing songs. Also noticed there is noise when I bring my fingers near the volume knob or input jack. May be the metal body is causing it.

I have this problem with the E10 which is all metal cased like the E11k is I think. Touch the metal case near the volume control and you get this crackling. It is very bad at times when turning the volume dial on my E10. This is why I sometimes prefer these things to not be in an all metal casing like my old E11 which has never had ths isssue.

Hmm, never noticed this. What type of phones/IEMs are you using?

I'm wondering if the higher impedance of my cans might be rendering this noise unnoticeable.

This isn't the E11k that I have, it just sounded like I'm having a similar issue with my E10 to what bobbynnd is having with the E11k.
 
I have the Audio Technica ATH-AD700s. They are around 32 - 35 ohms I think. Quite easy to drive.

Will this DAC reduce hissing on some sensitive headphones?

This isn't a DAC. If there is already hissing, all I would have thought it would do is make things worse. If you are using USB, the E10k plugged into a computer would get rid of all the hissing as that is a DAC. I don't think this will.

i wish they kept the bass boost 2 switch than just rather on or off, can anyone tell me how the bass differs between the old and new model

Bought this amp yesterday. I have awful EMI problem with it. Using it with a phone is basically impossible if the phone is not in airplane mode. Anybody else experiencing similar problems?
PS. I agree, it needs bass boost level 2 switch

 

[bobbyndd]

I primarily use it with my phone (Sony Xperia Z).  I use both EMI and over the head headphones. No problem so far. Some details like what happens when you turn off the airplane mode, which music player you are using etc may help.

Not sure if it's been mentioned (I searched the thread) but the E11K is now known as the A3 (Kilimanjaro 2) in Europe, not sure about the rest of the World.

I get a bit of EMI/RFI noise only if my phone is right against the E11k AND my phone has lost / is trying to re-establish a wireless connection - such as in an elevator or on the train.

Other than that, it's dead quiet. FYI, the phone is a BlackBerry Z30.
