… @Currawong could you share your first impressions on the S17 Pro and any idea when we can expect your full review ?

They are both great amplifiers. I found that S17 has more presence, control and punch in the low end and is more forgiving for brighter headphones like some Beyerdynamics models. S17 betters Sa-1 in driving ‘difficult/demanding’ headphones like HE6se. … I expect the hd6xx to be a good match for...

Agreed, thanks for the tip! I still have T90’s with both the balanced mod and high frequency mod by ‘Custom Cans’. On other amplifiers I always had to EQ them to further tame the 8k peak but on the S17 Pro they really shine as-is.

I believe you and respect your opinion. But I also believe that our individual hearing and preferences (yours and mine) are very subjective. Let’s accept there’s no real objective right or wrong (or best), like they say in Marketing: “Perception is reality” ;-)

Are you sure ? they do listen, response and advise where to get help when you have a service request. See above !

Did you consider replacement, I have the same headphone like you (HE6sev2 with 4.4mm balanced cable), S17 Pro temperature 55-56 degrees at 100mA and 10 degrees cooler at 50mA. Ambient/room temperature of 20 degrees. DAC is Gustard R26 connected via XLR balanced. I don’t have temperature issues...

Agree, I also have positive experience with Florian and Aune Europe, he was very helpful and offered me excellent service. If you return a product that has (minor) visible signs of use he has the right to not give you a full refund. Let’s not convict the guy based on one complaint of which we...

I recognize the lack of needing EQ on the S17 Pro, but from a music enjoyment perspective I personally consider this a positive characteristic. Ofcourse not every record sounds the same, it adds a subtle tube-like ‘character’, as the manufacturer intended, and the level can be somewhat adjusted...

In post #933 Aune is very clear with the below statement: “Hi, if there's a problem of your device, we recommend you to contact your seller to test it. If it's malfunctioning, you may need a repair or replacement.” Nothing ‘vague’ in that statement, to me.

As far as I know there are some unfortunate combinations with specific (low impedance) headphones that have higher temperatures but also those S17 units should not overheat when there is no (or another higher impedance) headphone connected.

MigueIP, an S17 overheating without anything connected at a room temperature of 20 degrees is not normal. When my S17 is powered on at 18 degrees room temperature it wil max out at 55 with no extra ventilation whatsoever.

Open a dispute at AliExpress because the seller sold you a defective product.

Hi cam, subjectively we might even prefere the sound of the worse measuring option ;-) All jokes aside, like you I was a firm believer in reducing the bits to 15 before sending the (HQPlayer) upsampled stream to my R26 and returning it to ‘default’ when I used my Singxer sda-6 (delta-sigma)...

Post in thread 'Aune S17 pro' https://www.head-fi.org/threads/aune-s17-pro.970060/post-17889081 R26 sounds spacious, dynamic and detailed. It already has a wide soundstage which deepens further when you switch to 100mA on the S17. It’s a nice combination with great synergy, I like it a lot!
