Try to compare your serial numbers, that is to say, all unit that have that "issue" on this forumHow do you know which serial are defective?

I got all inputs hooked up, surprisingly I don't see volume imbalance at all at 55/56 , 0/1 or any of the volume increments. I did multiple tests with Preamp outs- one via RCA and another vial XLR. I have circle through all the headphones outs as well.
I will keep listening and discover my dislikes as well, but surely recommend the amp.
Could you (and other S17 owners) please doublecheck my findings below:
We all know the 55-56 volume jump but is it just me or do we also have only 23 actual volume changes as my test below shows:
When I listen to my HiFiman HE6se v2 headphones and I increase the volume from 0 to 63 I hear the following pattern in volume increase:
0 = silent (step1)
1..3 are the same volume (step2)
4..7 are the same volume (step3)
8..11 are the same volume (step4)
12..15 are the same volume (step5)
16..19 are the same volume (step6)
20..23 are the same volume (step7)
24..27 are the same volume (step8)
28..31 are the same volume (step9)
32..35 are the same volume (step10)
36..39 are the same volume (step11)
40..43 are the same volume (step12)

58 (step18)
59 (step19)
60 (step20)
61 (step21)
62 (step22)
63 (step23)
… in other words from the 63 positions only 23 result in an actual volume increase.
I do like the sound and it is not really a problem but I can’t see the rationale.

In fact, neither do I. It is impossible for it to increase the volume every 4 steps. For this reason, in my opinion, either it's a batch of faulty amplifiers or I really don't know what to think. I posted the Pot schemeCould you (and other S17 owners) please doublecheck my findings below:

How much dB jump each step before the 55-56 volume jump? They better be very small dB jumps before that or this product is a no go. Or let’s say it should be a no go as that is bad bad. I might still get it if it’s a clear jump from SA-1, but would like this info.Could you (and other S17 owners) please doublecheck my findings below:

Each step has an increase, no gaps as such.Do you hear an increase in volume with each step up? I only get an increase every 4 steps
My Dac outputs 4.3Vms in Fixed line out via XLR, this mode S17 is at 17 to 22 volume level, max is 63.
I also tried variable out from my DAC, I end up at 40 on S17 and 20 on my Dac (Max is 99) via XLR. I do prefer fixed out from my dac due to the digital volume control which I gather could have audio degradation, not that I can sense.
Very flexible amp, I do now align with Aune marketing statement " The tuning is based on real instrument sounds and music pieces referencing, leading to the signature that is natural and full of musicality."
I was eyeing Violectric V281 Limited edition, but not sure if I need to drain my wallet anymore. I have not heard it but S17 checks all my boxes at ~1/4th cost.
It may also be that the increase in that range is so minimal that you don't notice it, but it is impossible for it to change in a clear and evident way every 4 steps. At that point, adjusting the DAC volume to variable and not fixed can come to the rescue. But then again, it's not possible for it to swing like this. They are defective units
As far as I can understand from the reviews, the Hifiman Susvara doesn't need more than level 55 in high gain, so if anyone needs to be above this level has really power ungry headphones and should have chosen a more powerful headphone amp- even as a preamp you should probably have a more powerful amplifier if you need to be listening above those levels. Anyone who reaches level 55 in low gain I imagine it could change to high gain and listen in lower levels.

Ok so there’s definitely an issue with the volume, no debating…the volume steps you are describing is exactly what i experienced with my first unit, but today i received a new unit and i get an increase every two steps up, literally every even number provides an increase in sound, no change in dac/headphones, just a completely different volume behavior in all, no huge jump for 55-56 like before, I’ll live with it because nothing comes close to this sound for this price, that i know for a fact, but aune really dropped the ball with this volume control.Could you (and other S17 owners) please doublecheck my findings below:

The amp is very transparent in a sense I can now detect noise from my EQ engaged at extreme volume levels which I could not sense in my chain before, this I guess is only possible as the noise floor level on the amp is very low which is good and the reason perhaps the way it does great on instrument separation and 3D sound stage.
I am sure feeding a R2R dac to this amp will do further wonders, I think this amp can help reflect better on your audio chain devices and further tune sound to your needs.
This amp also helping me to hear different sound aspects of my headphone collections in a good way, at the least the itch for new headphone is reduced for time being.

What does it mean? That the second unit has a different volume? So the debating is open...Ok so there’s definitely an issue with the volume, no debating…the volume steps you are describing is exactly what i experienced with my first unit, but today i received a new unit and i get an increase every two steps up, literally every even number provides an increase in sound, no change in dac/headphones, just a completely different volume behavior in all, no huge jump for 55-56 like before, I’ll live with it because nothing comes close to this sound for this price, that i know for a fact, but aune really dropped the ball with this volume control.
In your opinion, the Eversolo A6 fits upside the S17 Pro (for the shape)? S17 is 288x211x63 cm, while Eversolo 270x180x90 cm

- They are defective units
This is a strong statement. Do you own an S17 or is it all guessing and hearsay? ^^
But sounds strange that every reviewer didn't notice that or classified as an "issue"
Maybe because is´nt an issue, except for you.
As an example, my S17 has a bigger jump in volume from 40-42 with my AKG 712 Pro, but not with my other HP´s - this
does´nt bother me and this no reason for debating.
The S17 Pro is an stellar amp for his price and it has best sound i´ve heard from HPA´s under 2K.
the debate is over - now enjoy the music
