Of cause I havn't heard HFM, it's just thoughts.
I'm an engineer and can clearly imagine what item must to be the better in sound quality...
Here is the photos. Everything is clear from it.
Best regard's for everyone.

Did I say "AMP3 is not the league of Hifiman" here? Also I's answering your question of which head-fiers got the first three 801. Can't see why my answer is related to your current question.

I'm confused.

What's that grey thing in the first pic? Looks like a spider web

Sorry, It is not your word, but was Alex_Nsk conclusion. I just want to ask him he have no a HIFIMAN to compare with AMP3, how is can make a judgment?

Oh, I see, you can clearly imagine which one is the best sound quality? and try to convince us you are so capable to mod the player? it's like a fortune teller. You can thought and imagine any player's sound quality? could you tell us which field engineer are you engaging? and Which university teach you such an engineering method?

I am a stupid audiophile, I cost more than 10 years on practice on DIY audio. I have less progress on experience. For my ear is not golden ear. Maybe my head is also tin head for I can't imagine my project's sound quality. I can only testing, comparing, and changing and repeating practice. Is there other any clever audiophile can aslo imgine a the sound quality need not to listen just according to some pictures?

I' m neither an audiophile GURU nor magician.
I think that you forgot that all words had writing on this or any another forum(s) is just someone's subjectives. All thing I write to here is the only my IMO!
As for my profesional - I'm in D.P. degree of solid state physics.
Almost all of DAP for me is clear things, not BLACK BOXes how it could to be for many-many so called audiophiles.
The player which based on the good Digital Filter+DAC+good HP AMP schematic (HFM, aleXmod) could sounds better that ones based on descent SoC+OA buffer (AMP3) isn't it?
But if anyone compare the usual descent SoC based DAP with AMP3 it is clearly hear that last one is superior almost in all aspects...
Of cause the last comparsion must to be completed in simple A/B test, because audio is such subjective thing...
Somebody could prefer decaff coffee just for it's taste, but not me!

It is THE SOMETHING
I dont know what is it, just a kind of isolation covering factory aplyied for some reason I estimate.

Alex, is it possible for you to "kill" the hiss physically in the AMP3 dap? or impedance adapter is the only way to go. I think most of the amp3 users have problems with the hiss, for me it's the only big fail...

so was there an improvement with replacing the tantalum caps?

Do u hear improvement from ipod when it is imodded?
There is we have exactly the same result!
I'm sorry but I don't like to write about sound and my subjective impressions.
I think it is better 1 times hear the sound then 100 times read about it .
Some time latter I hope a couple audiophiles from my own city will hear, test and estimate the sound of diymodded AMP3 and my aleXmod and possibly write their thougths there and in alexmod thread.

Hello, I THINK what Alex is saying is that hifiman and alexmod, because of their design will probbably sound better then soic players like the amp3 (again, in theory). We must not forget here that head-fi is an international forum and for many people (including me) English is not our native language.
I too found Alex's statements a bit confusing and rash at first. But, I am still happy someone opened one of these players up to show whats inside.
Greetings, Anouk,

Not sure what's inside, but right now I have the Amp3 and a couple of inexpensive Klipsch S4s ($79) working together, and Sophie Milman's silky voice never sounded better, at least not on any of the DAPs I own. That's good enough for me. All this tech talk is making me sleepy.

Yeah, glad someone opened it up. Nice job. But really, the results are what matter to me.

As for hiss, the S4s do not hiss with the Amp3. Not sure why, but they just don't (which is why I am using them over the UM3X). I do have the new firmware onboard, but they still hiss a bit. None with the S4s, which are the first non-PAA-1 in-ear phones that don't hiss with the Amp3 (at least that I own).

To me, a $149 player that sounds this good is a nice thing to have. Would I rather own the HiFiMan? Of course, but I can't afford it. So the Amp3 is fine to scratch this particular niche, pardon the pun.

It's just your way...
As I mentioned befor AMP3 is THE ONLY DAP in which we can see the output buffer for driving the headphones. So there is a big step in terms of sound quality from ordinary DAP's based on integral codec and/or SoC's such as ipods, cowons, irivers and so on and so on...
All I want to say that there is no any magic, or complex scematics inside.
It is as simple as it can!
So if you searching for the best, just know that the AMP3 isn't in highest league of DAPs.

sorry, i am noob in electronic thing, but if we put buffer in the output can increase the sound quality, why other DAP not put it?? i think its not hard to just put it right?

Hi,think Alex is trying to say.A lot of devices use a multi purpose processing chip(its not just a simpler CPU,then all seperate circuits etc) ie can do sound,video,UI,all sorts of things.Regards sound it contains a DAC output amp etc etc.At least AMP3 uses a separate discrete,output amp stage.Which can lead to better sound quality.But you could go even more discrete & seperate the audio system even more ie seperate DAC etc etc.Which could be even better.
With multi purpose devices say PMP's its easier to plonk near enough one muti purpose chip in the device.But even if its the fastest etc etc,one out at the moment,dosn't mean say the audio quality as improved.
My thoughts anyway.
One of reasons say in Home HiFi forums,most peeps still use a CD player & not say a DVD player(unless really top end,or modded etc).They might have a seperate DAC,Pre-Amp,Poweramp etc.


Cheers BOB

ps then you can start modding with supposedly better quality parts/components,capacitors,even DAC's etc etc.
