    Not talking about the wifi icon...but the cellular data icon

    ...also what's the advantage of having an octa-core processor?

    Where do you see " dual SD slot " ? It seems to be only a single micr-SD slot ! this is why A&K advertise " 512 Gb max " ( 256 internal + 1 microSD 256 Gb)

    So do I get buzzing sound like I do when listening to music on the iPhone?

    The tray could (possibly) take 2-SIM cards or 1x SIM + 1x micro SD card...its on most smartphone now unless you're still on the backwards iOS eco system (don't flame me...just tongue in cheek comment lol)

    Still some way to go...if at all. Been waiting for my Geek Source far longer. what a bunch of fraud

    Back on topic...the technology of DAP (like KANN & SP1000) seems to have progress quite rapidly, but can we really hear the difference when compared to earlier gen DAP? Still loving my HM-901 and AK120 to bits

    I think I am going to wait a bit before jumping on the SP1000 band wagon. I jumped on the AK380 as soon as it came out and was frustrated with the player until the software got sorted. long story short it was returned and I went back to my 240. A year latter I tried the 380 again and was pleasantly surprised.

    I am sure AK will spend some time with software updates, and given that all AK players seem to share the same base software, I am sure my 380cu will benefit from some of these updates.

    Was really hoping for more internal memory.

    Oh and is it just me or does this thing look a little boring. the 380 has some largely useless angles and extensions as part of the case, essentially making it a little more outrageous in appearance than the 240. the SP1000 is just kind of meh.

    Maybe the amp will be outrageous in design. Perhaps the amp will be embellished with Swarovski crystals to enhance 'gemstone reflective and textual surfaces" of the SP1000.......:)

    The first DAP that uses AKM 4497 is Plenue 2, Have you listened to it? It sounds amazing

    You mean the right triangle icon? That's probably volume.

    One more day to go...and all will be revealed

    Yes, you may well be right. I could not believe it either.

    However, I wonder why A&K is so quiet about internal memory and output power up to now,

    Maybe they're holding some of the details for announcement at the Munich show this weekend.

    Thats why many in Hong Kong are selling their 380s and 380 CUs.

    The power output 2.2 for SE and 3.9 for Balance are not inspiring. Same memory capacity as 240 &380. The only cutting edge is the 4497 Dac. Let's hope it will sound significant enough and better than the 380Cu.
