Emotiva mini-X a-100

General Information

Don't let its size fool you. The mini-X a-100 is a monster - the perfect choice for powering a compact high-end stereo system, a zone amp, or a desktop system. The possibilities are endless, limited only by your imagination.

We created the mini-X a-100 with the same design and engineering standards as our full-size amplifiers. The a-100 delivers 50 watts/channel of honest power - and it does so effortlessly, with superb sound quality and lively dynamics that will satisfy the most demanding audiophile. Along with its great sound, the mini-X a-100 has the flexibility you need, including a front panel volume control, trigger inputs and outputs, automatic turn-on, and buffered low level outputs for easy daisy-chaining.

Just because an amplifier is small doesn't mean it has to sound small - or be short on features!


Best-in-class design and sound quality - same superior, fully discrete design and high-quality parts as its big brothers.
Flexible turn on - audio sensing turn on or external trigger.
Front panel volume control allows you to use the a-100 as an integrated amplifier or control zone levels.
Heavy duty power supply with large toroidal transformer.
Temperature activated forced air cooling - put the a-100 almost anywhere.
Buffered loop output allows easy daisy chaining to more amplifiers.
Full sized 5-way binding posts make it easy to attach heavy gauge wires, lugs, or banana plugs.
Dual color, illuminated ring on the volume control indicates power, fault, or standby status.
User selectable AC line voltage; 115 VAC or 230 VAC.

Latest reviews

Pros: Offers a forward, energetic sound and is often compared to many much more expensive products including the Lyr, often surpassing.
Cons: May produce a faint white noise slight hiss with some headphones, using resistors may help.
This review is based on matching the Mini X with Hifiman He-500 Headphones.  
You may be reading this review, unsure what to make of this Amp, asking how can a cheap sub $200 amp offer the power needed for an expensive Headphone such as the Hifiman He-500?  If you have done your homework you will find this is the stereo amp everybody is buzzing about, and for good reason, it powers these headphones very well indeed.  The Emotiva Mini presents the sound stage clearly and with a punch, yes you really do feel the bass thump with the Mini X, but not overpowering at all - simply precise and enjoyable to listen to and you may find more often than not tapping your foot along to the music - feeling the energy being fed into your ears.  
A fantastic match for Electronic music. 
One slight drawback to some listeners may be the presence of a slight hiss, sounds like a faint white noise. As you can imagine there's alot of power pushed out of the amp, an amp designed for speakers and not headphones in mind, it should only be audible whilst no sound is playing but once you start playing music the hiss will become inaudible and you should forget its even there.  According to some guys here at Head-fi, adding a couple of resistors should remove the hiss.
If you don't have huge pockets to empty look no further than the Emotiva Mini X.

I use it with 300 ohm resistors on my HE-400, and the noise floor is totally gone thanks to the resistors.
How, exactly, do you use headphones with this amp? I have never used headphones with an amp without a headphone out jack. I find this quite intriguing as it opens a whole new world of possibilities for headphone/amp combos.
Any help would be much appreciated. 
Not sure if the HE-500 comes with spare sma connectors, but the HE-4 does.  You can always connect speaker wires to the sma connector and than the other end to the banana plugs.  This will connect your cans directly to the speaker.  It does require a little DIY know-how and soldering skills.
Pros: Not expensive and solid state
Cons: Size for headphone amping use
Emotiva Mini-x + Oppo BDP-105 + He-5LE results in impressive sound quality, which is at least equal to Schiit Lyr with Telefunken + Uberfrost + He-5LE.
The Telefunken tube set cost alone exceeds an Emotiva.
The price of amp does not follow SQ.
However this test set-up does not necessarily mean that Emotiva mini-x is better than Lyr + telefunken.

I hooked The BDP to my windows machine through HDMI cable.

This pairing of Emotiva sounds like tube amp.
The speaker tabs are connected to female TRS jack, where two black output terminals are short-circuited.
Now volume is at 10:00, and I hear the same tuby sounds that made me happy when I first time bought Schiit Lyr a year ago.

It is very economic solution without big investment in Amplifier side.
There are so many positive reviews in this site with many machine configurations with Emotiva mini-x.

Now, try this, put your Lyr or your tube amp in front of Emotiva.
Tube amp => Emotiva => HE5
Some Emotiva owners have tried this and like it very much.
