This thing has a beguiling sound... smooth, refined, almost tubey, and very lifelike overall. It's an effortless and full sound, not harsh or bright or thin at all. Also, unlike my Bravo Audio Ocean, there is no loud pop sound thru my headphones on start-up. Another interesting note is that it's one of only two amps that I own where there is no noise when the volume is at max and no music is playing. All my other amps besides the legendary Objective2 make faint hiss and hash sounds in this scenario. So this thing is very well-designed. The owner of Rebel was a pleasure to email with, though he didn't have any RebelAmps available, so I had to wait and get one thru the used market. Very happy I did, and I hope for new products soon from Rebel. This, along with my Bottlehead Crackatwoa, are my two best headphone amps. I'm now making my exit from the gear obsession, I got all I need. Cheers.

Love this amp! The sound, the looks, and of course the maker. Great stuff!

Fantastic

The sound is amazing, running Audeze LCD 2.2, on Qobuz the medium gain setting is the highest I can go, using Wasapi exclusive, low gain is enough for 70% of songs. Plenty of power, and no hissing or buzzing with iems too! Sounds creamy and for 600 it's a no brainer.

Nothing negative to say about the device, it's absolutely amazing! Every single aspect of it screams high quality, from the smooth volume knob to the clean sound it produces, absolutely recommended.

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.

This is the best sounding amp I've ever heard hands down. I used to be in love with tube amps over solid state, but the class A magic adds so much magic to the sound in a way that most amps cannot achieve. It also has enough power for just about anything you could put on it. I genuinely hope to see more products from Rebel Audio whether that means more amps, or even just more colorways. (A yellow RebelAmp would be amazing).

All the reviews are correct. It is great.

Thank you for an easy purchase. I feel so bad for you guys. Good luck to all of you!

I have had the Rebel Amp for a couple of weeks now. I have been through a dozen or so amps in the last couple of years and the Rebel Amp is a keeper. It is detailed, spacious and fluid sounding. I am using this with a Lynx Hilo and it is much more enjoyable to listen to than the built in headphone out. The Rebel Amp is a good compliment to the Hilo's strong technicalities and sounds great with my Clears, HD600s and HD650s. It is lush without being overtly warm and detailed without being fatiguing. I ordered this amp at the beginning of May 2022 and it arrived in North America two weeks later. Artem and team are continuing to make and ship these amps. Count me as a happy customer.

Made all my headphones sound better
