Which IEM are you getting intense upper mids and some sibilance from with ur DX300? I do agree that R8, so far, is a bit above overall in airiness, texture and the higher frequencies whereas DX300 has more body and energy in the mids and bass. (Ultimately, complimentary). But I feel DX300 is actually quite laid back on upper mids and treble yet very smooth, so I can’t imagine any sibilance (from my IEMs at least).

I heard a little sibilance in the beginning but haven 't heard any hint of it for quite some time now. That is with any IEM or headphones I have.

Why is it burn in only “fixes” what people don’t like about an item? It’ll “open” whatever is congested, “tame” whatever is peaky, “tighten” whatever is loose, etc.? Why doesn’t anyone ever say it sounds worse after burn in if there are actual changes to the sound The mind is a powerful thing.

I don't think it will fix anything. What a product does is change and some people that hear the change are expressing what areas do change.

I only follow the manufacturers recommendation. This manufacturer actually includes a burn-in cable. If someone already likes the signature, it is very feasible there will be improvement. I don't think if you don't like the signature, burn-in will cure it.

It is as controversial as cables and FLAC...

When sibilance rears its head, my first thought is to examine the file (track) I was listening to.

That's interesting that you say no hissing with Andro.
Which Andro are you using?
Balanced or unbalanced?
Can there be such a difference to Andro Gold?
Both Max and DX300 are hissing yet without music playing and that is not like tiger-ear silent but can be heard without efforts.
Max I would say 50% less hiss with Andro Gold running balanced.
Only an ifi iematch does eliminate the hissing in my case

I checked again. It's Andro v2 balanced. You are right, you can hear it volume 0 or 1, plug and unplug. Also, it doesn't seem to turn off/mute the output for a while after stopping the music.

However, I would say that this is way better than the hiss I heard with N6ii/A01/T01 balanced. I could only use SE there.

So I'll take back what I said earlier, I will not be using Andro+Dx300 for quiet bedtime listening

Great point. When I had the Trailli demo, I was actually thinking to myself that I hoped the way it pairs with DX300 DOESNT change much.

I think technicalities tend to improve if the component implementation is strong, and in-turn, tonality may slightly change as well via perception of a “larger stage” or “more air” or “more controlled bass” And yes, I can imagine that not suiting everyone’s preferences. We just don’t hear of those instances as often

I thought DAP burn-in was snake oil until I just realized over time that my R8 sounded significantly better. Sure, maybe brain-burn in but I wasn’t actively looking for any changes. I revisited old IEMs like the Elysium that did sound sibilant with early R8 and those issues were remedied after “burn in”.

Either way, we know the power of placebo not just in psychoacoustics, but medicine, psychology, etc.

EE Odin. Definite sharpness in those upper mids/lower treble for me. Quite painful sometimes. I’m hoping it will smooth out

This is a very fair point.

Let me give it a try...

Absolutely. Poorly mastered tracks may well exhibit sibilance. But I’m making a direct comparison with the R8

Only from DX300? Odin tends to be upper mid-range intense by nature. I did love the R8 pairing with it so +1 there-but wow woulda figured DX300 would have been excellent for it. Fingers crossed

Any music specifically do you want me to try with DX300 and ODIN?

Don't feel pushed by critical comments.
It's all up to your personal liking and you can also go to bed with this pairing if you enjoy it
I checked your Andro V2 specs: it has 12.8 Ohm. My Andro Gold has 7 Ohm!
That can also make a difference...
I have quickly compared my Qudelix 5k and the Dx300 with the Andro Gold both balanced low gain
Will need more time to give serious impressions.
In short:
- Qudelix has a little less bass, less stage and details but is dead silent regarding "steam kettle" symptoms.
- dx300 has more prominent bass, depending on the track it's like a...kicking, even more than my full size Denons which are told to belong to bass queen category but it's to my feeling not sounding right but a bit muddy.
I will need to find some song examples regarding the mentioned bleeding into midrange
If the song mix is different it's like a disco machine.
There are songs where I feel like it's perfect on the DX300 also on my Andros, e.g. Summer Day Green by Wa'el, TOVE.
Immersive atmospheric holografic stage, warm tuning
Guitar notes vibrant.
Sigh...
"Stuck" by "Mira Lu Kovacs", also perfect on the Andros
Guys, I wanted to do some sports and am stuck listening here

Does the MangoOS support lyric display?

I have yet to see burn in do something drastic to tonality of dap. It can get a bit more spacious or controlled etc. But its never going to become something it wasnt made/tuned to be. I have not witnessed it ever.

If that was true. It would be dificult to manufacture dap with desired results.

Saying that you dont understand what tonality dap has unless you listen to it for 3 months is not daps problem.

Never seen manifacturer recommending burn in, and if they do its probably to make you miss your return window.

That said. I do agree it takes time to make review. Especially a useful one like say @twister6 where he actually puts in decent amount work in comparing number similar products so you have solid picture of how it sounds if you own or have heard at least one of those products.


Can i ask what iems/cans you are using? Thanks

It's called brain burn-in, or coming to terms with the hole in your wallet.
