Thanks

 

Not really.

 

Okay, it is a bit more complicated so bear with me here. SDXC comes in two standards: the current one we are using is the 3.0 version that also define SDHC. With 3.0 standard, SDHC and SDXC have the same pins configuration and power requirement. The difference is, SDHC uses FAT32 for formatting while SDXC uses exFAT. However, FAT32 supports up to 2TB, same as exFAT, so you can format a SDXC card with FAT32 and the SD reader itself should not know the difference. However, exFAT is a Microsoft thing so if you plug a FAT32 formatted SDXC card into a Windows PC, it will always ask you to reformat it back to exFAT - this is Microsoft way of trying to trick people to stick to exFAT. With a compatible card reader however (like the one inside X3), even a Windows PC will allow read/write on FAT32 formatted SDXC card. So in theory, X3 should support up to 2TB of SDXC card, right? Well, not so fast.

 

At current stage, the reading/writing speed of v3 standard is enough (SD is max'ed around 256GB while microSD is max'ed around 64GB). But once we move toward 1TB and 2TB, the reading/writing speed will likely not be fast enough. To solve this, the version 4.0 will replace the current version 3 standard. With version 4 card, it will requires extra pins and different power requirement. V4 card reader will be backward compatible to V3 card, but the V4 card will not work on V3 reader. So the simple truth is, though iBasso claims the DX50 is future proof, it really isn't - if the future 2TG SDXC card is V4 standard, neither DX50 or X3 will be able to read it. At this point, no one really know when V4 standard will be used, so claiming future compatibility is mostly just a wishful thinking.

I agree with ClieOS.
Fiio X3, X5 and iBasso DX50 have the same type / class of card reader. It is funny how iBasso over-confidently claimed support for 2TB microSDXC, yet Fiio conservatively and honestly said new cards will have to be tested first. I mentioned this twice at iBasso DX50's thread, but people/fanboys there either didn't understand my comments or ignored them.

Just typical marketing hype, but I do agree... I like FiiO's approach much better, as a consumer.

As long as the card is following microSDXC standard, increasing the volume normally would not make any issues....

 

But yes, I agreed with Fiio that for any new card, testing should be done before claiming any compatibility. This approach protects the company from unneeded customer complaints and preserves customer satisfaction on their products.

 

I would say Fiio is more customer oriented than iBasso from this issue. bigsmile_face.gif

James Fiio is a very frank and honest person when comes to technical questions!

He gains respect from all of us in this thread.

 

Hopefully Fiio can come out the X5 pre prodution sample soon so that we can know how good is X5 comparing to iBasso DX100 or even Hifiman HM-901.

I am sure X5 will be sound-wise high end DAP but unlike others it won't burn our wallets. Also James's honesty and communication with us are just priceless.

Thanks for the explanation.  It seems we are trapped between tech generation.

Seems a bit unfair to expect the X5 to hang with DAPs that are more then twice the price...

Why?

unless they're completely overpriced... "want to play hi-res files Sir?, that'll be $1000+ buckeroo's"... just because something is competitively priced does not demean what it's capable of.

ClieOs said the X3 is competitive with the AK100 at less than 1/3 the price of the AK100. FiiO simply is more honest with their pricing than some of these other manufacturers.

No, thats actually 1250 and tax and you get the privilege of waiting for a firmware update to actually get it to work.

that's only if the DAC's are compatible?

Don't forget the '''''magical''''' output impedances of both daps. Worldwide known 22 and 3 (or I should say 3.5 or maybe even 5 according to some measurements).

 

I agree with Achmed the Dead Terrorist, Fiio is honest and they bring quality to reasonable price they don't play marketing games and try to create hype. They ask real and acceptable prices for all of their products and always stay in touch with the community, providing honest answers.

 

Yes I also believe X5 will easily compete against highly priced high end portable audio sources. Especially it will be wonderful to see AK120 owners face. Pay 1300 euros and still have problems you don't even except to have in 50 euros dap.

 

FiiO and James know what they are doing. I like their way and honesty. They have my support anywhere anytime, they deserve it.

Just pointing out that his last name isn't FiiO. biggrin.gif

 

It's more of an username to clarify who he is affiliated with.

 

FiiO romanicized from Chinese is Fei Ao(alphabetical system of Chinese words and pronunciation of them). A term in Chinese which when directly translated means 'prone to fly'. But in reality, was developed by the CEO, James, to be a rough translation of "I believe I can fly" which is a common English expression, song lyric etc etc.
