Theoretically, as long as you format the SDXC card to FAT32 and the firmware doesn't have a problem reading over 64GB of files, then it should support up to 2TB. However, it will never read at SDXC speed, but limits to only SDHC speed. This applies to any SDHC reader as well.

 

Again, that's just in theory.

That'd be really nice, as at the moment i already have a shortage of space on my 64GB iPhone (50GB music, ALAC 16bit)

I think I've found my next player. It seems to check all the boxes: 24/192, support for every lossless format that I use, line-out without an LOD, output impedance low enough for my IEMs (Westone UM3X), removable storage, clean user interface... yep. Oh, and a price that won't leave my wallet crying in the bathtub and eating Ben and Jerry's biggrin.gif Buying one as soon as it hits the States smily_headphones1.gif

 

I love the apple-like ads too. Might capture some potential iPod buyers that way, who knows?

@JamesFiiO: will X3 outputting bit-perfect on digital out? how about the jitter characteristic on the digital out?

yes, it is bit-ferfect on digital out, for the jitter, it is about 600ps by AP tested. not sure whether other use different test condition, but we test some other DAP with 

 

digital output and the result even worse.

Hi JamesFiiO,

 

thanks for the prompt and be informative... I wish it could have a better jitter performance...portably use as the whole but when back at home plug it in to the external DAC at home..... but hey... maybe that's asking too much :)

 

thanks,

David

Thank you for the jitter information, James!  While 600ps sounds awfully high, it really depends on the meaurement method used.  When you say the result with other DAPs is worse which DAPs did you test and what was the measurement?  Did you test the Sony D50 and M10?  How about the Tascam 100ii? 

 

This is important to me, as one of my uses for the X3 will be output to a component DAC at home.

I have to agree with jj69.. :)... my nature would make me retrained to say it out :) but you say it in a good way jj69...

 

The jitter profile could be better... especially in this age of cutting edge technology easily found else where... with 200ps jitter is no longer acceptable today (remember the CS841x era?)... that 600ps seems really high...

 

referring to Tai's review/impression that the analogue result is very much respectable, I really wonder why the digital out jitter profile could be that bad... could it be because of the S/PDIF transmitter chip choice?

 

James, please reconsider again... having a digital out with such a high jitter would be practically useless...

What do you mean 'please reconsider'? The thing is already in production. And the thread starter specifically asked not to request any additions or changes to the spec. Let's discuss what is there.

 

Has anybody managed to actually hear the jitter? Is 600ps really that bad?

600ps is high, but as mentioned before, we don't know how it was measured, as other devices accordingly to James had higher jitter values. I think we'd have to wait for another test.

There are a lot of misunderstanding and flawed assumptions about jitter prevalent in this hobby. Here's one way to look at the actual effects of jitter (in terms of its contribution to overall noise):

 

 

As you can see 600ps is hardly catastrophic. It won't be detrimental in any appreciable way in real world usage.

Sorry to ask, I believe this was addressed before but I could not fine it.

Concerning UI and file management, does it support drag and drop?

 

I literally have thousands of music files, from years of ripping my extensive CD collection and later buying download files, and I often just pick and choose which files go into my player.

I hate Itunes and refuse to have anything to do with it, in the same way I dislike any music management system that manipulates my music files outside of basic operating system file management and foobar or other basic software music players.

 

Can one use drag and drop with the X3 and windows operating systems?

 

thanks.

Let us not ruin this thread with yet another jitter debate. There are tons of those at the sound science forum already.

I agree with anetode. Read some sound science and you will know that human ears cannot differentiate lots of spec's once they are good enough. For those who think 600 ps of jitter is high for human ears, do you know the jitter detection limit of your ears? Can you tell me the sound difference between 200 vs 600 vs 1000 ps of jitter? Please do some research on the subject first.

Drag and drop is fine.

So James who in the US is getting part of the 300 shipment mentioned on facebook. I want to know who to throw my money at in a couple of weeks. atsmile.gif
