Sorry to break it to you guys, but ears do adjust to sound over time.  :D  You're actually burning in your ears.  Try going from bright to warm headphones, it's very noticeable, then over time it sound fine or better.  It's like opening the shades and your eyes changing it's sensitivity getting used to the light level.

One thing I don't understand on either player is that gain sounds better on high gain even at similar volumes. It's not like you can turn the gain down and volume up with same result. Both players sound "thinner" with the gain set to low.

This has been my experience with all amps portable/desktop. I always use high gain for everything.

+1 bro :beerchug:

 

I started out as a hardcore skeptic for everything that was "audiophile," but after hearing changes in everything, sometimes dramatic, sometimes subtle I've become a believer.

 

I sincerely believe that some engineer in the future will figure out a simple reason why there is burn-in, while doing some non-related research he will stumble upon it and be like "oh this is odd..."

 

*When I bought my 2nd Fiio X3, compared it next to my 4 month old X3 with like 300 hours on it. It was VERY different. Haha. even my friends who are not into this kind of stuff spotted it easily. The new one has bass bloat and sounded muffled.

 I can't imagine how the digital circuitry would change (I used to do semiconductor reliability studies and look at the degradation in time to rise and time to fall signals in individual transistors and logic gates after slight over voltages) but maybe there is some sort of atomic diffusion that occurs in capacitors or something in the analog amplifier section that takes a time+temperature to reach equilibrium or something weird like that. Do you guys think that your stand-alone DACS sound better with time or just analog circuitry. 

 

I know someone said that batteries may make a difference and that makes sense to me since different batteries have different & non uniform discharge curves, but again I think that would also depend on the quality of the voltage regulation in the unit.

And I'm back to the DX50. Why? I don't really need the sabre double DAC when the wolfson DAC in the DX50 is almost as good as I have a 627 MICRO and also the sabre treble sheen got to me.

I don't know about the battery, but possibly the regulator circuity.  That all depends on how much variations there are for small circuit applications for these DAPs.

Believe me you are not the first one to have broke it to me :L3000:

Analog components is the underlying building blocks of Digital circuits. Those logic gates are after all a circuit made of transistors.

For me, I just go with one simple rule: "Trust your ears".

 

If I start doubting everything I hear there is no end. I go with what I hear.

Got to uk in 3 days, but I wonder if ill have to wait till tues to get it😯

put it on the marketplace and we'll all have fun at the ensuing bidding war that takes place!

I am not an electrical engineer, and do not want to start a big debate, but yes a transistor has a time dependency to it's on or off state but it is only ever read as on or off. If everything is working properly the transistor is read as 1's and 0's and is independent of the time required to reach that state. This is in contrast to analog circuitry where the entire time domain of the signal is passed through to each stage of the circuit. (Forgive me EE's if I got this horribly wrong)

At the end of the day this is the truest statement of all. I completely agree.

I agree.  Sound matters most to me. I can read specs and measurements, and understand the principles to a degree, but I keep in open mind, not try to be so closed minded that there aren't possibilities.  :beerchug:
