There’s no topic for it on the forum, but the Rebelamp is seriously good. It takes up quite a bit more desk real estate than the Topping A90 and doesn’t have any balanced outputs but every headphone I’ve thrown at it so far has been right up there with excellence.
I also find the Rebelamb to be very musically engaging while the A90, despite it’s off the chart SINAD, to be fairly sterile. It’s not an amp that I could recommend for brighter headphones while the Rebelamp doesn’t have any trouble there. Now the Rebelamp doesn’t sound like it’s adding any colour to the sound, it’s just a more enjoyable listen.
It also performs exceptionally well with IEMs which unfortunately the iFi Audio Neo did not. No noise with the MEST, Andromeda, Solaris, or Moondrop B2.
Really impressed with this unit and I am not looking forward to the day when @Resolve breaks into the office and ruins my audio setup to add it to his collection.
