Does the X1S have balanced output to the amp? If so, that is fantastic  How does the pair sound?

no x1s is only unbalanced , and x7 does not have any balance input

how does it have balanced out then?

  Aune X7S is the latest model in X series .It’s a pure Class-A headphone amplifier that meets the most demanding requirements, it’s also a mini high-end desktop headphone amplifier that can drive most of headphones and earphones .
 
Heritage----------latest Hi-Fi desktop headphone amplifier from the same designer who designed aune’s classic Panda and B1 headphone amplifier . 
 
Compact size ----------Slightly larger than the CD Disc , X7S’s flexibility apply to diverse listening environment as study/bedroom/office . 
 
Powerful ----- Equipped with 8pcs power transistors that split into 4 groups for true balance output, along with ±15V regulated power supply result in a powerful driving ability.
 
Class- A function: X7S was set in Class-A mode at 38mA static current of each output transistor, it results in a full bodied, wide soundstage and warm sound character.

Excellent measurement results--------Frequency response: 20 ~ 200 k + / - 0.3 dB, noise: 3 uV, THD + N: 0.00013% ——truly dark background.
 
Sound tuning – both nature and musical, according to the real musical instruments and based on the understanding of music connotation. Various renowned headphones were used in listening tests, such as T1、HD650、TK701、IE80、IE800、HD800、HD600、DT880、K240.
 
Multifunction-----------With three gears of gain adjust, X7S can drive most of headphones and earphones on the market.

Balance/Single-ended output -------Four independent sub-circuits constitute the 
 
Additional features------waiting for you to discover.
 
Global products ----------Developed with the assist of the Britain’s industrial design team, it will be launched in
Munich Hi-end show on May 8th,2016 .
 
 
Batch launched time:  May 8th, 2016

how can an amp with balanced out not have any balanced input?  I was excited to see its balanced but now I am just confused

 

[XSAMURAI]

 
how does it have balanced out then?

this is my question , too

 

[harpo1]

Could do the same as the Liquid Carbon and use a phase splitter to turn the SE signal into a balanced output.  I know I can't tell the difference on my LC when I a/b between the SE and balanced inputs.

 

[XSAMURAI]

i think the only reason they put the balance output on device only for drive high impedance and hungry power headphones , not easy to drive such as HE-6 or HE-1000 and other planar , using balance output for more power

 

[EvilKillaruna]

 

 
Yup, that's exactly right. I'm testing X7S right now and it can't drive my K1000. Instead, where this little thing really shines is PRE section. Tonality wise, X7S is fairy neutral amplifier with good low-end control, positive transparency for various sources and with non-fatiguing highs. It's very complementary versus X1S with soundstage more focused on depth and imaging than width. You can also hear it in PRE mode and that's why it can be a cheap and VERY effective addition for your system. With my DAC-80 and M-35, on K1000 you can hear clear difference in plus due to that.

What's the GAIN of the unit and what's the distortion @ 1700mW with 32 ohm XLR ?? Is 1700mW still in class A or only to some point - like up to 1000mW ??

 

[mtoc]

CROSSTALK < 92dB?
 
crosstalk no good

 

[JungleApe]

Any information about the output impedance? @AuneAudio

 

[EvilKillaruna]

IIRC, 10 Ohm.

 

[Talisker90]

Now that it's been out for a while, does anyone have prolonged experience with the market versions?

 

[moby1974]

Anyone tried with LCD2f, bright/neutral/a bit warm?

 

[paradoxology]

I received an X7s today to go with my excellent X1s DAC and I am very pleased. It is strong, articulate, and just a bit on the warm side of neutral. It drives my Fostex T-X0 very easily and I am looking forward to trying it out with my other cans! Very pleased, indeed!

 

[cgouy]

Any thoughts about adding to this amp, the XP1 power supply that Aune offers?
