(i would post links to the spec pages but I`m not sure about the forums rules).
From AKM website, I could not find AK4353 but AK4480 the one used in HP-P1 is not the best DAC chip.
The best is AK4399 because it has the highest S/(D+N) and lowest THD.
AK4399 is quite a serious DAC though. That's what Fostex uses in its desktop DAC/Amp, HP-A8.

4399 is gonna be a bit of a battery hog as well, also needs a bit of babying to sound its best. supports native DSD too, wonder who's going to be the first portable dac/amp to support DXD/DSDiff formats

I met up with my VentureCraft friend today again and this time to check out the Samsung Galaxy S3 hooked up to the Go-DAP X. What's interesting is that the Go-DAP X was working perfectly well with Android 4.0.4, no Jelly Bean 4.1 required (although it did work with JB 4.1 too).

 

VentureCraft mentioned that unlike PC USB (host?) mode, the Go-DAP X doesn't draw power from the phone. The recommendation was to put the Samsung music app at full volume, then control the volume via the Go-DAP X instead. There was only 1 track that I listened too off the Samsung but it did sound pretty good (off VentureCraft's AKG 701, and my UM SE530x8 Snoopys). This was a stock Go-DAP X with BurrBrown's OPA2134.

 

Note that this works with the Samsung Galaxy S3 Android 4.0.4 and 4.1 for now, but doesn't work (reliably) with Sony's Xperia models with Android 4.0.4. However it looks like when JB 4.1 is released by al service providers, we may have a very 1st device that's supported on both iDevice and Android platforms without any jailbreaks, root, hacks, tricks, or workarounds.

 

Some pix of the Samsung with Go-DAP X. Note the Android version 4.0.4, and the USB connected and disconnected whenever I switched the Go-DAP X on and off. Also last pix of the Go-DAP X with the Apple Lightning cable :-

Still think they should make that damn cover already that encapsulates the SGS3 and the Go-Dap X... that rubber band is annoying and lacklustre. 

 

Samsung built USB audio into the S3 thats why it works, it has only been added to Jelly Beans spec, but I am not sure its even compulsary?!

They have a case for the iPhone already so I don't think it's too hard for them to have a case for the S3. The iPhone case with Go-Dap X :-

@AnakChan: As Venturecraft is testing Lightning at the moment, do you perhaps know if this will require a 30-pin adapter, or will it go straight from Lightning to USB?

When I met up and talked to them on Tuesday, they still don't have the iPhone 5 itself as such haven't done any testing. However, I believe they are planning on connecting directly from Lightning to USB when they get an iPhone 5 in their hands.

Thanks. That sounds promising.
(Off topic: also interesting to see see if Lightning will go to 3.5 as well, for people who don't need dac's)

I imagine Sendstation or another company will make something like that.

  • iPhone5/iOS6 and Go-Dap X Releasing Date

  •  
    Go-Dap X releasing date in stores will delay to be on Sep. 29th (ship from us on 28th) due to iPhone5/iOS6 modification.
    We again truly appreciate your generous understanding and patience in this matter.
     
    We are also working on Go-Dap Unit4.0 verification with iOS6 at the same time.
    We would like to announce about the results within this week.

It appears the Go-DAP X is now shipping and due the delay, for the first few orders they're shipping the Go-DAP X with some extra cables. In the pix, I noticed a micro to micro USB LOD is included for the Samsung Galaxy S 3C. The X is also fully compatible to iOS6 & iPhone 5.

I am confused where to look for pictures of the X model on their website. Is it the same as Unit4.0? Specs the same? Help please.

Thanks I've read the thread from the beginning. My brain-eth runnith over. Does the final use the AKM AK4353 for DAC?

And it communicates with the Apple proprietary software like the Solo and Fostex?

The X uses the same DAC as the 4.0. And it does support iAP but also USB audio. The one difference between the X & the 4.0 for iAP is that the X supports all iDevices including the iPod Classic. The 4.0 supports only those iDevices with iOS.
