post #5686 of 19811

Hey guys, my E17+E09 haven't arrived yet, but i'm wondering. I noticed the E09 has a 10 Ohm output. Isn't it a bit too high for the HE-400 35 Ohm only impedance?

Yup, it is. I have heard that the hifimans aren't too picky when it comes to output impedance of an amp, but idk for sure

I had the same combo before the lyr and it's a very good pairing. I'm really not too hung up on numbers...I prefer to go by ear. And to me ears the e09k on low gain with the e17 sounded very good.

I hope you're right.

 

In any case, do you have any other amp recommendation to use with the E17? Something more in the warm side, maybe?

The e09 is a bit on the warm side. One of my favorite combos before I got the lyr was e09 and odac. Very nice!! The e17 just can't hang with the odac.

I got mine running on a bunch of Fiio products and these sound pretty good.  I cannot compare to any higher end devices as I'm new and have not bought higher end equipment...yet.  

 

This is a Galaxy Note 2 -- Fiio E7 -- Fiio L9 Line Out -- Fiio E11 (high gain and bass boost) -- HE-400

 

 

This is the HE-400 with the Fiio E17/E09k (make sure lobypass is set on the E17)...along with my AKG K550.

^^ Looks good to me!! You don't have to spend a lot of money to amp/dac the he400 to an enjoyable level. It's one of the selling points.

The problem with odac is that it's usb only. I need a dac with spdif input.

 

Is E17 that worse than odac?

I'd like to know how good the e17 DAC is too?

The e17 dac is pretty good, but ODAC is a step ahead. Better resolution.

Is there any dac in odac's league with a spdif input?

why not high gain? and what volume did you leave e17 on.. im doin gain on e09 + e17 volume 55 no gain.. but only 50% volume in my music player as any higher distorts ez for some reason (ive tried replaygain etc doesnt do anything)

There should be, but they may cost more. The ODAC is already fantastic value.

^^ Amps always have a better sound when you can use the lowest gain and still get the volume that you are looking for IMO. Start low and then move to more gain if you need it, especially with the he400.

For most dynamic headphones, yes. However, the planar magnetics, output impedance is an absolute non-issue. It does not alter frequency repsonse like it would with lots of dynamics.
