Dan Clark Audio AEON 2 - Open & Closed - Official Discussion

I’ve just had a had a chat with Andy from Dan Clark Audio.
I’ve had a problem with my Aeon Noire.
We talked for ten minutes on the phone and he got what’s the problem.
He will send me a new cable for free. I mean this is really awesome by him.
Thank you to @taronlissimore and to all the headphones.com staff for their kindness and the help in solving this little thing in a moment so hard for us all due to COVID 19.
It’s highly appreciated

Some impressions on different results on powering Aeon Noire.
Definitely this is an headphone that changes according to the power you feed it with.
Anyway, with my surprise, with some portable devices you can get some decent to good results.
Dragonflies Red and Cobalt have the same current output but they differ in the chip that feeds the current and in the digital filter.
While DF Red definitely isn’t enough to properly drive the Noire, with Cobalt you can get a decent result. Decent means that you’re still losing something from the headphones especially in complex passages in music and in fast dynamic changes. But using DF Cobalt with Audirvana on Macbook Pro isn’t that bad and can be a decent compromise on mobility.
The results are similar with Astell&Kern SR25.
On single ended output you will lose some details but in my opinion mobility means you have to deal with some compromises and the warm tone of the headphones pairs very well with the warm tone of the DAP, without emphasis on basses and turning a little down some occasional peaks in treble.
This combo definitely satisfies me as long as I can stand losing something while saving the possibility of listen to my music while I’m aways from home for some days and I can pack all my stuff in the smallest possible size.
Things start getting more interesting with the Chord Mojo.
I’ve used it in direct output (when turning it on simultaneously press the two volume buttons), using all the power the small lipo battery can feed.
Paired with Audirvana and TDR Nova what comes out is a very good sound, very smooth and rounded. It looks like Noire tuning can handle the harshness of the Mojo.
You end up with a sound balanced and pleasant. A really surprise to me.
No loss of details with the Mojo, some dynamic passages aren’t at their best but we’re talking about a mobile solution and there is always some compromise to deal with.
In home listening with Lehmann Audio Linear is very good in quality and fully gives access to all the potential of the headphones.
Setting the gain to +10db (there are some little switches on the bottom of the head amp to finely tune the output) you have enough power to properly drive the Noire without distortions and getting all the finest passages in music.
The sound loses some of it’s warmth and gets more Harman like which isn’t bad with classical and jazz music.
With Schiit Asgard 3 the Noire make a stunning combo with a resulting sound which to my ears is very analogue and warm. Treble gets some steps down, mids come out better and basses are emphasised but not in a negative way at least to my ears.
Listening to Mika Vainio “Last Live” from Editions Mego on vinyl brings out all the dynamics of the album and even the faster passages are fed in a pleasant way (link to the album: https://mikavainioemego.bandcamp.com/album/last-live).
As a summary these are headphones that are meant to be driven properly with a good amplifier to get the most out of them.
The tuning that comes from the internally perforated pads anyway gives you the possibility of enjoy music from powerful enough mobile devices if you accept to sacrifice some details and finesse in change of enjoying your music while you’re away from your home equipment.
I hope it can be useful to the community.
Stay safe and enjoy.

I’m thinking of selling my AEON 2’s and want to gauge interest. I’m a professional audio engineer, and have been using the AEON 2’s for editing spoken word content. I bought a pair during the Summer of 2020 that developed an issue, and received a brand new replacement, with perforated pads, about a month ago. I moved my home studio setup to an acoustically treated and sound-isolated space, and find that I don’t need high-end closed-back headphones anymore. Just want to gauge interest and see if anyone wants to buy my pair. I don’t have the original box, but the headphones are in mint condition and would be shipped in the carrying case they come with (in a generic padded box). Asking for $500.

As I wrote in the “Thank you!” Thread I had a problem with my Aeon Noire cable.
Andy from DAC has been so kind to chat with me at the phone and find out what the problem was and send me for free another cable.
I have to say that apart from fixing the electrostatic problem I had the new cable (Summer one, the same in quality as the original one) working properly has changed SQ and did it for the better.
The high response from the Noire was sometimes improper to my ears and the mids weren’t as good as I hoped.
Probably due to the electrostatic interference.
Even with a ultrasonically washed vinyl I was experiencing clicks and pops when my cartridge encountered the smallest grain of dust. This was highly affecting the highs reproduction.
With the new cable the Noire sound to my ears extremely balanced with full, pleasing basses, mids much more present and smooth and highs no more hurting or distractive from listening.
I wrote in a comment about Focal’s Célestee that miss aren’t the best thing with the Noire (in comparison to the pleasant mids of the Célestee).
With the new cable the Noire totally changed and mids are now perfect to my ears.
The whole sound is now less fatiguing, much more relaxed and fun to listen to.
I use these headphones a lot for my University reaseraches about Alvin Lucier’s psychoacoustic music.
These sound can be fatiguing in long period listenings.
While with the defective cable after a two hour listening I was experiencing the need to stop listening for a while now I’m in the middle of a 5 hours listening with no fatiguing at all and no need to take a break for my ears.
I hope this can be useful for the community and for those who are looking at the Noire.
Enjoy.

People at Dan Clark Audio are great. They are in San Diego about an hour from my home. Went to their place to have a quick repair on my Ether 2s. Got a free DCA shirt while they were fixing the headphones,.

A really good experience.

I auditioned the Aeon 2 Closed with an A&K S25 and found the S25 held up well, though just barely. I was comfortable at 135 out of 150 on the S25, which was loud but not earsplitting.

By comparison, my new Focal Celestees seems to be handled better by the S25 - more room for more volume.

Anyone considering the Aeon 2s for use with the S25 should be happy, I’d expect.

For what it’s worth, I’ve found that the Aeon Flow Closed (1st generation) performs relatively poorly on anything less than a powerful desktop amp. Its delivery scales up with increased current delivery. My AFC sounds shaky, compressed, and cloudy on a weaker amps.
