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 a discrete output stage. Thanks to low noise floor and smart ground topology RebelAmp easily handles IEMs or sensitive headphones.
Allows driving high impedence 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 the volume of powered speakers/power amplifier.

this is my second class A but it it's my favorite. i am very impressed about it being handmade in Ukraine. very nice work and detail. seems to power all my headphones with plenty of headroom. green is my color of the month
Makes my Oracle MKII sound so much more spacious and much detailed. my class A addiction might very well start from here. Thank you Artem and team for still making this amp despite these trying times
I have the Topping D90SE and A90 Discrete. Running the RebelAmp right from the DAC, I can understand what the boys are saying about the creaminess. Preamping with the A90 Discrete was the reason I was interested in this. Yes, turning the volume all the way up on the RebelAmp, as R. below describes. The RebelAmp adds a more delineated sound stage and a presence that is what I was not finding in the Topping stack alone. There is just that touch of Class A that makes everything more fun to listen to.
Out of the box RebelAmp is very warm and spacious, but in time you will realize it does not appear to be very powerful, nor detailed specially with smooth DACs like Qtest, so how do we fix it?
1st. get a pre-amp (you can also use a normal headphone as pre-amp). I use an Archel Pro that I had around the house with volume at 9-10 o'clock with Qtest, while Neo iDSD runs at -20-ish DB.
2nd. turn RebelAmp all the way to the max volume. The volume pot cuts away quite a few details so we need to get rid of it.
3rd. Leave the rebel amp ALWAYS ON. At start it is a little harsh, but after a few days, it will become completely smooth AND detailed.
With this setup you will get a very powerful detailed and smooth amplifier. It has more then enough power to PROPERLY dirve non-stealth Arya. (for nor Arya users, yes those are really a bitch to properly power).
Do I still recommend RebelAmp? 100% YES. Even if you factor in the pre-am cost, it is still has an outstanding sound and for the money.
It can easily be an end game for everyone who will not go for insane headphones, and that is really more then 90% of audiophiles.
Very nice piece of equipment. Adds a bit warmth and forwards a notch the mid-highs /highs. The rebel amp powered my Hifiman HE6 SE, almost as good as Violectric V550, which is at least 3-4 times more powerful, and >2k EUR in price. Big thanks to Rebel Audio team. Looking forward and hope to see a balanced amp in future.
