   I was shocked to find that this inexpensive amp would sound so amazing and can compete at the same level as amps costing 10X more. You get lots of detail, the 3D imaging and sound-stage was very expansive. It never sounded harsh or clinical, on the contrary it is a very smooth sounding amp inspite of the level of detail it produces. This amp is a real bargain. You will not be disappointed. The built quality is apparent the minute that you open the package, it is packed like a piece of jewelry. The amp itself is very solid and heavy for a its size. The amp runs hot but that is a feature that makes it sound at its best, this amp will not sound nearly as good when you first turn it on and it is still cold. It takes sever weeks of playing it to “break it in” and for the amp to flourish and reach a full bloom. So you have to be patient when you first get it because you will only be hearing half of what this amp is capable of doing when it is new out of the box. You get a choice of connectivity to the source between RCA or XLR, it will sound better using the XLR connection as this amp is fully balanced.

   A sleeper, amazing clarity and detail. It does run a little warmer than most, but produces great sound. I use it as a preamplifier line level and it compares my reference tube preamp costing 4k. Oh, a keeper due to its ability to extract all the detail at low volume levels so at night no need to crank it .

   When it’s warmed up to 55 C degree or more, with XLR output, it sounds warm, full and detailed. I used Gustard R26 as DAC. It matches ver well with HIFIMAN HE1000se. Pretty good with ZMF Verite Open and Focal Utopia. The drawbacks are 1) you need to turn it on and wait for 30 minutes to let it heat up to 55 C. Otherwise, it doesn’t reach the potential for that best sound. 2) it will reach 62 C in my case after 1 hour. Very hot. 3) although others stated 100 MA sounds better than 50 MA, I did not hear any obvious change.I ended up return it. Instead, I bought a Violectric HPA V222. It sounds similar and bit more transparent for V222. The night and day difference is the operating temperature. V222 stays in cool room temperature after hours of listening. If AUNE can reduce the temperature to more normal level, this is a great value.

   I’m enjoying this headphone amp a lot and am looking forward to trying different and high quality headphones.Right now I have the LCD-X, my favorite, Sennheiser HD600, the Beyerdynamic T1, and Meze 99 Classic.My dac is the Denafrips Ares12 (has the upgrade). Using XLR connections from dac to amp. It does get hotwhen using max power but that is not necessary for me at this time and I have added footers under the amp for better air circulation. Very happy and at a reasonable cost.

   I upgraded to this from a Schiit Asgard 3 and it has been a big improvement in sound quality. When you want a detailed sound that makes everything wide and dynamic the standard 50mw mode will deliver that especially if paired with a very clean or neutral DAC. However I find that it when paired with my SMSL SU-10 can make some things a bit bright if they are not well recorded. But the good thing about this is the 100mw mode which smooths that out and adds a warmth that can take care of that for you. The low gain is enough to power all of my headphones which includes HE1000 V2 Stealth, Meze empyrean, ZMF Atrium, HD 660S, and Focal Elegia with a good range of play with all of them. I’m not finding that I’m typically listening at more than 35 with most of them and like 20 with the focal since its so efficient. I use single ended for everything and never feel like any of my headphones would really benefit from more power. I never hit the 50-something some people say the volume level skips at so I wouldn’t even worry about it. And if you do than just throw it on high gain and not worry about it. I keep mine on my desk in my living room and I put it on some cheaper spacers just because it does get warm but not like burn your hand warm. Typically at 50mw mode single ended I don’t go above like 48 degrees and with 100 mw mode single ended I don’t typically hit more than like 58. It will go above like 60 if you decide to use the balanced on it though. But even then you still have hours before it would hit the max if you ever get it that hot. It does take a little time to warm up in both 50 mw mode from off so I just keep it on all the time. It takes less time for it to warm up in 100mw mode form 50 however it like 30 minutes and that’s fine. The only flaw of this product is that there is no way to switch between the pre-out and headphone out so it’s always outputting to both. With this amp and my SMSL DAC it increases the sound quality so much that running the pre-outs to my powered Vanatoo speakers makes them sound much better. But evetime I want to switch between headphones and speakers I have to unplug one and re-plug the other which is annoying. But the sound improvement is worth it for now until I can get a more permanent solution.

   This amp is making me listen more . I use it for a hifiman he1000se and hifiman he6se v2. Both headphones perform and sound great. I alsonuse a laptop cooler and at 100ma Nad high gain its about 50 degrees. The value is insane and better than a lot of expensive amps.
