Wrong section of the forum mate. Also generally speaking not all scientific papers are of the highest quality, so it's good to critically evaluate if findings are statistically significant or recognize study design flaws or biases. All good an fun to keep linking and quoting studies but unless it's a meta analysis I wouldn't put too much weight behind these individual papers.

Statistics. I love statistics.
You can find on the net (the ones I linked, and the ones the links link themselves, are only a small part of it) a lot of scientifically conducted (as is, again, real people, no agenda, some basic knowledge of physical processes and theory of measure) studies which shows the inability of the human ear to pick apart signals when the delta is under a given range.
I would say a statistically significant number.
Can you point me to a single, scientifically conducted study, where scientists and audiophiles got together, and verified that human hearing can indeed take apart audio signals which differ, say, less than 1e-3 (or even 1e-2, FWIW)?

Like the previous poster said... this is the micro iDSD thread.

This thread has already gone way off track and I dont want to incur the wrath of the mods, but I will say from my experience and medically speaking, these studies rely on the fact that human hearing can be standardized, When it really cannot, at least not uniformly across the board. Hence why audiograms are used diagnostically because we have been able to standardize its application and account for patient hearing variations.
 
Remember the whole blue and black vs white and gold dress debacle not too long ago? And thats what we know of so far. So that to me nullifies these studies in being able to conclusively conclude one way or another whether human hearing can tell apart these audio signals or not. Which is a lot more nuanced as it included the entire auditory tract from the outer ear all the way to the auditory cortex and believe you me, there are enough variations in human anatomy to be able to safely conclude that no two people hear or see exactly the same. 

That is all I will say on this matter as this discussion is better suited to the science forum and its taking away from what the thread is meant for, discussing the iDSD Micro.
 
 
 
Speaking of which, I STILL havent fully run out of juice despite it running for hours at a time, albeit connected to my MacBook. Tried it with my PS3 the other night and hot dang does it bring the games to life. Gamers should def give it a chance

That's not what you said. You said that all amps sound the same. You did not even say "solid state amps". Which, if you say that about tube amps, then you should probably be worried about your hearing being damaged or something.
 
In the 3 links you posted, one is unrelated, one is dead (and questionable since we don't know how sensitive speakers were used, and how experienced the people were in discerning sound) and one is about a guy who claimed that he can duplicate a sound of any expensive solid state amp by a DIY amp with cheaper components (again, totally unrelated).
 
If you think THD is all there is to an amp, that's fine with me, I just think you should find a different thread to evangelize.
What is the point telling someone your subjective opinion, when all opinions are subjective, because all are based on one's own perception, which is subjective?
Throwing "science" around won't help, because the brain science to reverse-engineer human perception simply is not there yet.
 
Also please be civil, no need to call people names like "the batman club".
 
Here, two amps compared -- please go tell the guy he is dreaming and that all amps sound the same -- go ahead: https://headmania.org/2016/09/27/ifi-pro-ican-headphone-amplifier-review/

Agreed.
I would wish you'd make the same remarks to folks which tailed this thread after my post, with unrelated conclusions, up to putting in my mouth things I have never said, in the hope of getting a point, which would have never gotten if the conversation were to be continued of a scientific path.

We had PS4 > micro iDSD > Senn HD650s at this year's Gadget Show and the kids wouldn't get off Battlefield 4. We heard a kid say ' I can locate the snipers as I can tell where they are firing from.'  Another kid said, ' I heard a grenade explode 50 yards behind me, awesome.'
 
It did make our day. The only thing that didnt make our day was when they fought over the controller as they waited patiently but some wouldn't come off the machine! One of them got a ticking off as he threw the controller at a kid and it hit the monitor screen. Kids!

Wondering if there is any way to clean/fix these marks on my Micro... Not sure how it happened, but I think my laptop was involved. 
 
They're either from the rubber feet on the bottom of my macbook pro or it was metal on metal rubbing :/
 
Is there any way to buff these out? I'm not sure if they're marks or scratches...

Hello Guys,
 
If i plug the micro idsd to my pc through the usb cable that provided with the box while im listening it will be charge up fully and stay 100% till a detach the usb cable?
 
What is the difference between the 2 mods USB Power Mode and Battery Power Mode?

If your PC's USB ports support BC1.2, then yes. If not, no - though if you are using micro iDSD in Eco mode, it is very unlikely you will able to drain it in any significant way. This topic has been covered many times in the past in this thread, you might want to search them out.
 
If your PC doesn't have BC1.2 but you want it, you can also buy an USB hub that supports it.

My iDSD has stopped working reporting some kind of driver issue; just after a slew of Windows 10 updates.
 
Anyone else?

I have had issues with mine after updating to osx sierra. I have not updated the firmware so that'll be my first step but anyone else experience issues? I have had to unplug my iDSD a couple of times to resolve static issues. I am using the blue USB cable that came with the device.

I also recently updated to Sierra but am not having any problems with my iDSD. I am, as far as know, running the latest FW. You might want to check your default settings in the "Audio Midi Settings" in the Sierra utilities folder and verify the Bit/Sampling rate. One other option is to try resetting the Pram (NVRAM) when restarting your Mac. Search procedure on Google.

Thanks. I had forgotten to check those settings. My default is 32bit 192k. I am not sure if this changed from previous OSX but I'll reset the NVRAM as well. Won't hurt to do that.

utee05, we tried on a Windows10 based PC, loaded with full batch of updates. Everything still works as it should do. Tested on Asus SonicMaster laptop.
