RebelAmp by Rebel Audio is for people who love music. Simple and minimalistic.
You can read a brief story of how and why RebelAmp was created here.
It's a class A amplifier with discrete output stage. Thanks to low noise floor and smart ground topology with audio in mind RebelAmp becomes suitable for IEMs or sensitive headphones.
Allows to drive full-size headphones like Audeze LCDs and many others.
H-L-M It’s done that way to avoid switching from Low to High gain by mistake.
With it you can switch outputs between headphones or power amplifier and powered speakers without disconnecting cables.
Use it to control volume of powered speakers/power amplifier.
Competent circuit design
Eliminates pops and thumps when turning on/off amplifier.
Only quality electronic components are used in RebelAmp.
35VA toroidal transformer. 4 power rails and total 80000uf (yes, you got that right - eighty thousand) of filter capacitance.
2 year warranty
RebelAmp is covered by 2-year limited warranty that covers parts and labor.
If you didn't like your RebelAmp you can send it back to us within 15 day after receiving it. Restocking fee will be applied.

Coming from two rather analytical amplifiers, I wanted something more colored/relaxed sounding. I looked at some options, several tube amps for example. Eventually I decided to get the RebelAmp which I knew about because of Zeos. I gotta admit, the looks of that thing played a big role in that decision. Now that I've had this thing for a few weeks, I can confirm following aspects:
The RebelAmp looks gorgeous.
It has great build quality.
They have more than enough power for my Hifiman Arya (35 Ohm but 90db sensitivity).
A slight boost in the mid-bass and smoother treble make the sound warmer.
Now something that I'm not really sure of is that it possibly also made my headphones sound wider. Might be a slower decay in the sound.
As all my expectations were meet, I can say these were 500€ well spent.
This is my first headphone amplifier, so I have nothing to compare it to. It does it’s job (amplifies audio) well and drives my headphones. I really like the look of it as well, looks great on my desk.
Just remember to get a 3-pin power cable for when your amplifier arrives as this does not come with a one (as per the product description).
A thoroughly enjoyable amp, all the better for its simplicity and sound. I can't fault the hardware, and it will remain one of my daily use audio items! The sound is excellent and demonstrates clarity and space that punch above the price point.
Some small caveats: The packaging was terrible, and even lacked a power cord. Additionally, in the UK I was seriously stung by customs charges. Not necessarily the fault of Rebel, but it should be made clear. Just enough to knock one star off, because all of these things are important when these products cost in the 500+ range.
Keep it up Rebel.
Hello sweet people,
Started out hifi with a RME ADI-2 FS DAC and headphone Beyerdynamic 1990 DT Pro. I knew the RME Dac was good and I could use its DSP to tweak the Beyer to my personal taste, it produced an overwhelming nice 2-dimentional audio portrait on the RME headphone outlet post, I was simply baffled.
But after a while I could figure things can improve, somehow. Despite only few reviews of the rebel-amp on the net I jumped in, lo and behold this added that lustering 3rd dimension to the music and lesser-to-non of necessary DSP, only +2dB bass for my ears. I consider the headphone stage of the RME as good, but the core business of the RME is imho the DAC functionality, and the core business of the Rebel-amp the headphone stage, now both working in the best of their talents together.
My total hifi investment is now 2k€. For this particular level of sound it is an economic responsible investment and subscribing to the rebel mentality ;)
On the net I've read some persons want more horsepower decibels, I do not completely understand, even on LOW and my 250 Ohm Beyer I've never crossed 1 o'clock! This is on USB feeding the RME DAC.
I do find however using the Toslink feeding the RME I suddenly have to increase volume a lot on the RME so it's output signal into the RCA lines keeps equally healthy.
I suppose if people have a issue with moderate sound volume, to check if they are not feeding the rebel-amp inputs with too low a signal strength. The green box itself is able to blast your brains into the neighbourhood no problem.
PS: receiving the rebel-amp had me paying extra 123€ on EU-import taxes (to Belgium) per UPS. Rebel-amp carries an EU-make sign yet border officials saw a straw to milk me some, but this is fastly forgotten when current feeds the green wonder of blissful sound, it makes me very happy.
Its like slathering a thick spread of class A Ukrainian butter on your toast (but with headphones).
