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...
