To eliminate the possibility of poor power supply, can you connect another amplifier to the same outlet?
I just turned it on again - no whistling sound. I'm just wondering if the noise was caused by overheating. The amp gets warm with daily use, but I don't think it's hot.

ve great confidence in my Rebel Audio amp manufactured in the Ukraine. I have four Ray Samuels headphone amplifiers made in the USA with the oldest one over one and a half decades old and still going strong (18 years). I also have three Beyerdynamic amplifiers that are manufactured in Germany. My two headphone amplifiers made by Headamp here in the USA are also bullet proof. Those four brands are very trustworthy and I have confidence in them having long lifespans.


Is there a retailer for rebel amps in the EU?

Quality control and lifespan is a reason why I stay away from topping and hifiman.

It is unlikely that the noise is caused by overheating. It was very hot for me this summer. The amplifier was heating up very much, it was not comfortable to hold your hand (65 degrees or higher). There was no noise. If there is noise again, try plugging another amplifier into the same outlet. If the noise is repeated on another amplifier, it means that the problem is unstable electrical power supply of the network.

Purchase is from the Rebel Amp website only.

I love them all! But if we are talking about favorite as far as value, then the Darkvoice 336SE and Little Dot MKIII are super FUN sounding amps for the money. The Darkvoice when found for $200 and add about $20 in tubes gets some magic going on the cheap and probably edges the MKIII out on value. However, having a variety of tube amps and plugging into each on the fly is the way to go. Mullard tubes seem to have been my most listened tubes of late. Not that they are the best, just that the headphones that I have been listening to seem to gel well with them.

they sounds amazing, but sometimes too bright to my taste and music playlist
Try the High-Z, will soft the sound
