Just wanted to stop in to say that its been just over 2 years of owning the Rebel Amp and its solid.
Sounds awesome paired with Adi-2 and Cascades, and also with my active Audioengine HD6.
As others have said in this thread, you won't need to look elsewhere for a while if you get one and this definitely reflects my position on it. I don't swap out hardware too often, so this is practically endgame for me.
I use it with IEMs sometimes, there's no audible noise on low gain. You do hear the noise floor on medium gain, but you would go deaf if you played anything on medium anyway.
So I just got the Rebel Amp. Traded my Jot 2 for it. Pairing the Rebel with my Bifrost 2 connected to my Mac via USB. Comparing with my Feliks Audio Echo Mk2. The verdict is still inconclusive. Listening with my Aeolus. Definitely sounds more open (brighter?) than my Echo Mk2 and Jot 2 (to my remembrance). Seems more revealing as well which can be good or bad depending on the song being played or headphones used. Gonna try my HD6XX next. Also going from low to medium gain is a big jump in volume.

Is the Rebel new or new to you? Give it, like any SS h/p/a, break-in time. You may want to experiment (at same actual volume, not the knob position) with the different gain settings. There can be subtle SQ differences.

Some are in the camp that Class A should be left on...despite being a power sucker. I had the Rebel and Jot 2 for a while and never noticed a difference between leaving it on 24/7 and turning it on/off. I ultimately decided to keep the Jot 2 because the Rebel sounded a bit dry for my preferences.

I actually left mine on all weekend. Barely got warm. Still room temperature. Not sure if that had any effect on the sound but it didn't seem to hurt anything. Not sure if the Rebel sounds dry to me but it seems more open sounding compared with the Jot 2.
The Rebel is a true class A amp, so leaving it on 24/7 is really quite wasteful. And the output MOSFETs have a negative temperature coefficient, so if there is any effect, it will be that the amp will run deeper bias, have lower distortion, and possibly sound better when *cold*.
TLDR, I really think there is zero benefit to keeping it powered on, or needing significant warmup.

Well perhaps it's wasteful in terms of using hydro when not being listened to. But when I first turned it on after getting it I didn't really like it. Not sure if leaving it on made any difference or I'm just getting used to the sound but it does sound much better now.

Assuredly brain burn in. There's really nothing in the design that burns in. And the design is universally accepted to sound better at higher bias, and bias reduces as temperature increases.
