Well, the way they work inside electronics is the same... not remotely far different.    Calyx M comes with its internal storage + micro SD + SD card and there's no known storage issue for that either.   It depends on iBasso's skill level. I don't believe someone who makes living from...

  Other manufacturers haven't done it yet, right. That's why I'm asking iBasso to do it.  It's about time to see a super DAP with enormous storage capacity for DXD and DSD256 files... don't you think so?    It costs less than $1 for that kind of storage slot...   ...

Even one SD card guarantees 512GB for only $180 now.  Ideally, one SD plus one micro SD or four micro SDs.

  Well, it depends on skill level of engineers at iBasso.   As I have said, this $10 SD card reader can read up to 7 flash storage devices.   https://www.amazon.com/niceEshop-Multi--Memory-Reader-Windows/dp/B01DXPST8I/ref=sr_1_16?s=pc&ie=UTF8&qid=1468960321&sr=1-16&keywords=sd+card+reader...

  Send Paul a message and beg for an SD slot! 

    I don't believe they're completely final until we see an actual product.    Who knows? LH Labs have published hundreds of pictures like this but Geek Wave's not yet to be finalized.    Also, I doubt about the space..... this is apparently going to be thicker than Calyx M which sounds...

    They should do four micro SD card slots.     But guys... why are you guys so worrying about SD card slots??   You guys purchase Calyx M, HM901 which come with SD card slots... correct?   Then why not DX200 which is almost equal in size?      Everybody's so happy about SD card...

I don't believe so.    They can make changes if they want because it's still yet to mass-manufacture and ship.   Putting two more micro SD card slots will not hurt them.

SD card and micro SD card consume nearly no battery at all.   They have nothing to do with battery life. If you put 10 SD card slots and stream movies from all of them, then maybe but having 4 micro SD slots for music streaming will not kill battery since 3 of them will always just idle.   ...

Nope, we need to beg to developers until they finally understand that their DSD-enabled devices need bigger storage and it doesn't cost them more than $10 to implement two more micro SD card slots or perhaps two SD card slots.   Please send Paul a message to update micro SD slots!    a DXD...

512GB is still great... better than 200GB x 2.  Ideally, I would like to get two full-sized SD slots inside battery cover so I can't see them from DX200's exterior.   iBasso will realize 400GB is not enough for DSD users.

  True. 512GB SD card is only $181 now... it was $800 when it first came out.  How can we miss this deal on a DAP...

  2TB Samsung T3 SSD plus DP-X1.....   This OTG setting works. and Samsung's T3 is small enough to carry in this manner.   But I bet this T3 SSD will drain DP-X1's battery pretty quickly. DP-X1 lasts about 10 hours on its own. If it needs to feed an extra 2TB SSD, I think it will last 3...

Let's hope. Please them a message :P 

Forget OTG man... ask for 4 micro SD slots.    Send messages to Paul.    Honestly, I think it's lame to carry so many cables and gears around. One DAP and headphone are good enough to look outstanding...

Man, that's a lot of hassles. I already tried 2TB Seagate Wi-fi HDD to send files to DX100 over wifi... It could play some but those wi-fi HDDs have short battery life and relatively bad wi-fi signals.    Let's just beg for 4 micro SD slots so we won't have to deal with such hassles.

two isn't enough for me... :(    no good for SACD files....  you can put less than 100 DSD albums in two 200GB micro SD cards.    Four micro SD will be more suitable for heavy SACD DSD users.

  I don't really get why you guys are so worrying about having 4 micro SD slots inside DX200's metal cover.   Guys at iBasso won't have to pay more than $5 per a micro SD slot at their factory. It's that cheap... and it's always better for us to have more of them. 

  Not true... a DSD128 album or DSD256 album is 5GB to 10GB. DXD album is 10GB per each. You can put only 20 of them into one 200GB microSD card. You can put total 40 DXD albums into two of them... it's not that many. You need four microSD slots if you want to make the best use of DXD, DSD 256...

  Yeah, so I requested iBasso to put two large SD card slots in DX200 but it got disapproved.    One 512GB SD card is $199 now (it was $800 when it came out).   I would go with four micro SD card slots then... then we can still get 800GB (four 200GB micro SD cards, each costs $60).

Not true. 256GB is maximum for micro SD now and it costs $199 as a brand new.   Its original retail price was $240.    Do you think if they make a 512GB or 1TB micro SD, they will sell it for $70?  Absolutely no. They will try to charge $500 to $700 per a piece, I bet. Then none of us can...

Can you guys do four micro SD card slots then?     There's a 256GB microSD card from Samsung now. https://www.amazon.com/gp/product/B01G7L03OS/ref=ox_sc_sfl_title_8?ie=UTF8&psc=1&smid=ATVPDKIKX0DER   If you guys implement four micro SD card slots on DX200, we can get 1TB.    Please do...

If they can make a completely error-free stock player with completely functional, smartphone-quality touchscreen, I would like that over foobar2000 too.  However, in the past cases, they have so many issues and firmware update nearly doesn't exist.  If a product gets so many negative reviews...

Please implement proper firmware, OS, quality touchscreen this time.   Completely forget about DX100. That doesn't exist any longer!!!   I hope to use Foobar2000 on DX200. Foobar2000 is still the best for playing high-res files on desktop.    Please let Foobar2000 android use internal DAC...

  So, AK70 is for balanced out... its single out is not better than iphone out...   DP-X1 vs Calyx M please?
