Great review again. I bought this a few months ago and it instantly became one of my all time favourite purchases. My 4 Zmf's , empyrean and radiance all sound fantastic on this amp. No question it is my end game headphone amp, I cannot imagine how anything could make my music more enjoyable. I figure if you are happy, just enjoy being happy. And this amp make me very, very happy. Pure joy every time I use it. I put it on 1" speaker isolation pucks after reading about the heat. It gets warm but not what Id call hot, my feliks echo ran hotter. I also have the aune s9c dac which is excellent as well.

hi, have you noticed an improvement in the s9c pro since you first listened to it and after a while?

Thank you. Very good review. I have owned the device for almost 5 months and can confirm most of what has been said. Unfortunately, I also have the problem criticized by many that the device overheats and shuts down after 2-3 hours in 100ma mode. Another point of criticism from me is the display, which is praised in this review. I see it completely differently. I don't like the fact that the display can neither be dimmed nor switched off. The layout of the information shown on the display could also have been better. If, like me, the device is positioned so that you look down from above at an angle, the information on the top can no longer be read. It is completely unnecessary to put the four outer pieces of information so close to the edge.

I recommend purchasing the AC Infinity Aircom S7 ($50) as noted above. This will keep the amp at about 50c in the 100ma mode at the lowest fan speed which is silent. You are welcome.

That's a great point about the viewing angle of the display. I did notice that the visibility drops off quite fast at an angle, but it didn't effect me in normal use so I didn't think to discuss it in the video. It seems there might be some product variance in the heat side of things. Perhaps inconsistent application of thermal paste on the heat sink?

Your output is tremendous! Thank you very much for all your work and the value you provide.

I think I've missed something here, Jim.

So I have the S17 Pro and I’m trying to understand how you say it’s grainy in the top end and not warm because that’s not my impression of it at all. I suspect it may have to do with the DAC, at least when you were using the Chord-I can’t speak about the Yggy really, but I found the Hugo really dry and harsh. In fact, I thought the Archel was harsh when I tried it with the Hugo and then it wasn’t harsh at all when I switched to the Apple Dongle. I have my S17 Pro connected to a SMSL VMV d2r and it sounds super smooth and warm to me and I love it.

@PassionforSound

Ай бұрын

It's all about relativity here. Keeping the DAC consistent (and it doesn't really matter which one) while swapping amps, it was the treble character that most separated the S17 from the A3 Pro, Mjolnir 3, Prelude and Soloist. It's not massively grainy or harsh, but there's a little refinement to be gained with higher level amps.

For anyone tried the both units this is better than mjolnir 3. Especially how it drives high impedance cans compared to schiit unit. I have a beyerdynamic T1 V1 headphone set. Both are not good as for ex Violectric 222 on that but for me S17 is the winner overall of this 3. Great for its price. Dac i use is gustard r26. 😊

Another good review, big fan of your work. So, I have owned a MJolnir 3, and currently have a V222 and S17 Pro. The S17 Pro can make beautiful sounds with great bass, but often not as clear as the V222. The trade off being that the V222 can be aggressive and give me a bit of listening fatigue; the S17 Pro is a more relaxing listen, but you sometimes wish for more clarity and detail. I have also noticed that I prefer the S17 Pro on some albums and the V222 on others, so no clear winner IMO. Now, the Mjolnir 3 is like the V222 and S17 Pro had a baby, all the details and beautiful notes with hardly any fatigue. Sadly, I had to let my Mjolnir 3 go because I found it unreliable and fussy, however others have not had these issues. I have had audio ecstasy at certain times with the Mjolnir 3, unlike any listening experience I have ever had, but in the end it just wasn't worth it to me. The V222 and S17 Pro represent very nice listening experiences, but the Mjolnir 3 can blow you away. I think I am settling down a bit on my audiophile journey and am just going to enjoy what I have. I wanted to try some different headphones and amps, and I have done that. Now, I am just going to enjoy the music for a while and stop analyzing (ha ha, all audiophiles say that, stop tempting me Cyan 2!)

Thanks for sharing your impressions!! That's a really interesting comparison between those three.

Thank you for your continued fantastic reviews as you obviously fit the moniker you have chosen. I do agree with the bulk of what you said about the character of the A17Pro which I purchased at the NYC Canjam to mate with the Hifiman HE1000SE headphones, and I must say they are a very good pair together that I highly recommend as a combo platter. I love the headphones but my only concern was about the slightest edge to the treble. I actually found the amp calmed it down to my liking. I listened to the prelude and the schiit amp as well with the HE1000SEs at the Canjam and would agree that the A17Pro does well against them. I actually thought a notch better, but this could very well be my ears wanting to have the A17Pro best the others reinforcing my ego for making the 'right' choice. I could not A/B the setups as the tables were all spread out and I might have raised some eyebrows and eire if I attempted to stretch long cables in this crowded event. (Maybe it would have worked with traffic cones? What do you think?) Besides the obvious choice of music, this pair works very well for watching streamed content by bumping up the sub-base region with my Mojo 2 EQ for a bit more impact. One other note that may be of interest to those looking into the A17Pro. To keep the temperature to a controlled range in the 100ma mode I purchased the AC Infinity Aircom S7 component cooling fan ($50) that has a very similar footprint to the A17Pro. If you use some rubber isolation feet on top of the Aircom S7 this will allow for excellent architectural support for the A17Pro to sit on. At the lowest setting which is only a 2 watts of draw, it is silent and effectively keeps the amp at 50c or slightly below when the base temp turns on at 23c. (Please note that I do wait until it is warmed to 50c to engage the fan as the Class A circuitry prefers some warmth for best operations.) By the way, at the CanJam I purchased both the above Amp and Headphone combo at a substantial discount as demos. As such, I also highly recommend any CanJam that you CanCan attend if you are in purchasing mode. Happy listening!

Thank you, Rob! I'm glad you feel that way

Thanks for the informative review. I've had the S17 for five months (and it was a significant upgrade from the Liquid Platinum that I had been using) and I both agree and disagree with various points. Like you, I can discern little to no difference between 50mA and 100mA mode (though many do), however I do generally run it in 100mA mode. And I have also found the volume knob to be clunky for changing functions and it generally takes several tries to input changes correctly. However I disagree with you on the sound signature (at least for my ears, we all hear a bit differently)--like many reviewers, I do find that the S17 has a somewhat warm (or tubey) sound. It certainly adds a bit of warmth to my Hifiman HEK Stealth, which many find overly bright. (Though it is probable that the somewhat warm Denafrips Ares 12th-1 R2R DAC adds some synergy to the mix.) I've had a somewhat worse experience with heat than you, though not nearly as bad as many others. If you follow the Head-Fi thread on this amp, it is impossible not to conclude that there is significant unit variance concerning heat, which is troubling. Despite good ventilation and aftermarket legs that raise the S17 nearly an inch above the Ares 12th-1, as spring comes to New Jersey I have found it necessary on warmer days to use an inexpensive fan to prevent the amp from reaching 69°C after several hours of operation and automatically switching from 100mA to 50mA mode. Why Aune chose not to add additional venting to the case (which has only a small and inadequate number of vent holes on the rear) is a mystery.

I wonder if those people who heard warmth from the amp were using more neutral headphones, and so it was easier to notice.

I'm more curious as to what amp is being used as the reference for what's warm/neutral. I compared the S17 Pro to multiple amps and with multiple headphones (neutral and coloured) before drawing my conclusions so I'm guessing that points of reference might actually be the difference here. The heat thing is definitely a slight concern so I do agree on that one that there might be product variance.

Thank you for your reviews. You're one of the very few that mention/factor in soundstage depth. Regarding the claim of the best amp for under $1k, would you recommend the S17 Pro over the Soloist 3XP, given that the 3XP can be had used with a supercharger for around $700? I've been hearing great things about the S17 Pro, but I've been waiting for your input.

I would probably go for the Burson, but with the expectation of also upgrading the op-amps to the V7 Vivids. Without that swap, the tonality of the 3XP can be a touch metallic in the treble and that's where the S17 Pro can have an edge, depending on tastes and the headphones being used.

Thank you for your responses. I've had my 3XP for a year or so along with the supercharger. I just recently swapped out the V6V opamps to the V7V's and the V7V's have tamed the occasional shout and glare that the stock 3XP would exhibit. Considering the cost of a used 3XP, supercharger, and V7V opamps, one could get a fantastic performer of an amp for ~$1k usd. Sounds like I'll be skipping the S17 Pro. You've saved me some money, for now... Thank you!

@PassionforSound

That's very hard to assess because the moment it's in a preamp setup, it's staging performance is directly affected by amp and speakers downstream. Unless you were to be able to quickly switch between two different preamps feeding the same amp and speakers, I think it's more a test of the downstream than the preamp, especially if those comments are comparing the headphone performance to the preamp (i.e. speaker) performance. The S17 Pro has full influence over the headphones, but only partial influence over the speakers.

You’re totally right about the top end being a bit bright! I find it weird you didn’t see the difference in soundstage depth going from high gain to low. Mids are much more forward with less depth in high gain and also the same effect going from 100ma to 50ma. Low gain and 50ma are the only way I enjoy this amp.

You need to be very careful when switching gain modes that you match the volumes exactly. What you're describing is exactly the effect caused by having the amp slightly louder after switching to high gain. 🙂

Hi Sully and thanks for the kind words! I'd be looking no further than the Schiit Mjolnir 3 for the HE-6. It will be an awesome pairing. Your sums about power requirements are quite a way off so don't worry about the power output of the MJ3. It will handle the HE-6 fine unless you're listening at dangerous levels of doing extreme things with EQ. 🙂 If you're concerned about the power output still, the S17 Pro is your next best bet.

If im paying 1k for a HP amp i want to be able to adjust the sound to exactly how i prefer it.

@@PassionforSound That's why I said it

It is the ONLY honest review of S17 Pro. All other paid reviewers just keeps on lying about it. Sadly I was fooled by them and bought one... Not satisfied at all. Sound is not bad, but far from the miracle the reviewers were suggesting. There's two notes to this test: the sound is changing along with temperature changes, so the sound is fairly different at 50 degrees and 68 degrees. And for me there is az audible difference between high and low gain: low is more detailed, high is more dynamic. Alltogether I plan to change it for a better amp.

Sorry that you're not enjoying the S17 as much as you'd hoped. What are you planning to replace it with?

There is no difference between the sound of high and low gain if you adjust the volume to be at the same level. I suggest a Topping product for you since I feel it is more suitable to your aspirations/expectations.

@@petermartin9494 You probably try to insult me but you're just suck at it. There IS difference, period. There is also difference in sound between different temperatures. Maybe you just don't have the ears to hear it. Try some topping products instead.

Honey, that's really not very nice ♥️

I have the Aune S9c and love it. Not sure I need the S17.

Probably not. I suspect the S17 Pro is a slightly better amp, being a dedicated device, but I suspect you'd be better off taking a step to the next tier up if you ever decide to add an external amp.
