The EF400 only accepts digital inputs, either as a USB-B or USB-C. The only RCA jack on it is an output. So, no, you can't connect an analog source to this amp.

Well that's a shame~ I guess I'll have to continue my search for a new amp elsewhere

A german reseller just listed an EF400-Rev2. I am a bit surprised because there was nothing announced as far as I know. Can you proof this, @TeamHiFiMAN ?

Probably the batch with the fixed static noise issue.

My question is, does anyone know how many volts the Hymalaya DAC outputs on the XLR connectors? Anyone who knows the exact answer, please write! Thank you!

And how many volts on the RCA connectors?

I saw a review that mentioned Balanced out sounding better than Single-Ended on this unit, If true, how much of a difference is there? I only have a stock cable for my Edition XS and same will be true for HE-R9 that I'm planning to purchase.

Also, If I connect IEMs to the unit, how much volume range will I get? and is there any hiss with the unit?

What's the static noise issue @Mansinthe86 mentioned.

There is a noticeable difference with my headphones HD6XX and especially LCD2C, the dynamics are increased, bass slams a little harder and overall sound becomes a touch more ticker. With IEMs though the difference is not significant.

With my IEMs Blessing 2 and Kanas Pro on low gain I can get around 11-12 o clock on normal recordings and on quieter recordings I can get past 2o clock. I would say that is a decent volume range.

I don't have any noise issues with my unit.

Well, I guess I need to get a Balanced cable for my Headphone. I don't see why it would be but is there a difference between 4.4 & XLR?

 

[Johnfg465vd]

Has anyone compared or seen a comparison of EF400 vs Ares II? I'm pretty much set on getting the EF400, just want to know what I'll be missing out on.

I don't have XLR cables but I read that there's no difference between them ports.

Hello friends, here is my opinion on the EF400.

https://www.head-fi.org/showcase/hifiman-ef400.25881/review/29050/

Super musical and engaging with power to spare!

I am surprised this unit has not gained more traction. While not perfect, I am super impressed. I am sitting here with a Bifrost 2/64 and a Jotunheim 2 and I think they'll have to go back to Schiit. While the Schiit stack sounds good, it lacks the cohesive feel I get with the EF400. I feel the treble and sound stage are better on the Hifiman. To me, it just pairs better with my Edition XS and Arya SE. I have a sneaky suspicion that ASR would have a field day with this combo, but honestly, it just sounds good. Highly recommended by this random guy on the internet.

I purchased mine yesterday, hopefully it'll arrive soon. How long did it take for you to burn in this DAC?

Any users of HE-R9 here? How does it pair with the EF400?

@jfox8 I plan to use mine with the Edition XS too, I think it's warm, laid back sound will pair nicely with the detailed and slightly bright (to my ears) Edition XS.

I think you will find that it pairs really well. I was running the Edition XS through a THX 789 and a Modius DAC and it was too much for me. The EF400 toned it down just enough to make it very enjoyable listening experience.
