You forgot to add the brain and different people's ears to the equation. You can prove that differences exist, but it is another thing if the brain or ear can not perceive those differences.  There are a lot of things in life that can be measured with equipment that a human's ears, eyes or brain...

  How does this affect you?

less than a second.  Just enjoy it

There is no audible difference between WAV and FLAC.  They are both lossless, which means no loss of data to the file.  Use FLAC and forget about it or read up some more on Wikipedia what the difference between Lossy and Lossless is.

  When you say blow them out of the water are you talking about the LG V10 sounding louder?  Did you level match them?  Of course the louder sounding phone will sound better.  That is how are brain works.

  iPods are not limited to 32 gigs.  You can buy one that has 128 gigs.  Granted, they do not have expandable storage.

Oops.  Sorry about that.

Thanks for the comparison! Just a correction Brooko, I am pretty sure the Fiio X3II and X5II have internal storage. 

The cable is fine. It looks good also.

I thought we were moving past the science stuff.

This is just the law of diminishing returns

  I agree that spending money on better IEMs will make the most difference in sound quality.

The thread is over a year old and you still did not give him a comparison :confused_face_2:

  Don't you hate it when a company tries to sell you a $3500 DAP that is sterile?   Wait until you hear the silver version.  The copper one will sound like crap also.

I think you need to type more in caps and use more punctuation.  We don't know how to read in lowercase.   Unsuspecting public buying thousand dollar DAPs on a whim?  Say it isn't so.

if 5% conductivity matters that much in audio sound, then what do the tin, lead and carbon sound like in the capacitors and resistors.  Also, what about the nickel plated stainless steel connector, what does that sound like?   Since we are sharing our experiences with audio and cables....  ...

  so the electrons are moving at 2200 km per second, but you need another 432000 seconds until the sound will change?  When you really break down this stuff you post without putting anything behind it, it really does sound silly doesn't it?  How exactly do you know you need 120 hours?  What...

  I and others agree with you, but iBasso does not believe this needs to be fixed.  It is this way on all of their products.  

Was there ever any doubt that this was not the case?  Why would you try to appease the .001% of your market vs. the rest of the population when you can never really satisfy audiophiles?

Your English is great. Both of the players are great and both have their quirks (I have not heard the Xduoo X3).  I think you will be happier with either one.  The DX50 has physical buttons as well as a touch screen.  The X3 has a bunch of buttons at an angle.  I prefer the DX50, but the X3 is a...

This is Head-Fi, where everyone needs to upgrade to the new shiny, even if it sounds the same or worse.  A&K has figured it out and just keeps increasing their prices while making small changes, like the material of the housing and people snatch them up.

  Uum, not really.  First you said the iPhone was not suited for IEMs, because of the hi output impedance.  The low output impedances were posted and now you say a 1 ohm impedance difference changes the bass.   The Shure SE846 has a 9 ohm impedance at 1 KHz.  At 60 Hz, it is 16 ohms, so 2 or...

What is the iPhone 6S/6S+ output impedance?  On the iPhone 5 it is 4.5 ohms.  I don't consider that high.

Sure. Just not in this thread :wink_face:
