Yes, I couldn't resist the temptation. biggrin.gif SXC 24 extension cable doesn't affect IE800's sound signature at all which I am really happy about.

Cool, thanks for the heads up.

The build quality from the pics on the ALO site looks very professional.

It is definitely weird at first sight or from ANY photos I have came across but kudos to the AK team to go for an unorthodox but very usable design.

 

Not really if you actually hold in in the palm of your right hand.  The sharp lower right corner really digs into the flesh of your palm.  It's basically best to hold it with your left hand.

From a controls standpoint, it appears to be a right-handed DAP -- hold in the left hand while controlling the interface with the index finger from the right hand.

Agreed.  The design does seems intended mostly for right-handed users to hold it with their left hand and operate on the screen with their right.  I usually use my left thumb to access the ff/play/rew buttons, and left index for the top power button and volume knob.  Right hand swiping at the screen.

Hmmm.....time for an AK240-L, for lefties.

 

Shouldn't be a big deal to reverse the values on the NC program that mills the case...;)

For those who do not want to spoil their AK240 with some cheap IEM:

 

vision-ears VE6-xcontrol¬†at 1900‚ā¨ =¬†$ 2500¬†¬†¬†:eek:¬† for a¬†total $ 5000 set-up with the AK240 !¬†:D

 

 

It has a switch for 2 different SQ Signatures. Nice idea, but...Since I just received my Roxane, I will wait a little....;)

AK240 - Working

Never had a doubt of the 128GB card working with all Astell&Kern players, as it's evidenced several times in the AK100/120 thread by using a MicroSD to Standard SD adapter ribbon cable. Anyone care to dig up that pic?

 

And as far the sound quality goes, not only do the dual CS4398 DACs get involved, but we incorporate the XMOS audio processors into the AK240 to assist with the native DSD playback. 

 

For balanced output, we have a simple way of how it works at our webpage: http://www.astellnkern.com/eng/htm/ak240/ak240_feature01.asp. Scroll to the mid-bottom of the page under "Balanced Output".

The only doubt was in Sandisk adhering to the tolerances of the MicroSDXC standards.  Their 64GB MicroSDXC Extreme cards were a tiny bit out of spec, and didn't make full contact with connections in some card slots of some devices that had no problems with other cards.  Good to hear the new 128GB MicroSDXC is working well.

I am a bit confused about the balanced out on the AK240. Can you explain what is the difference between using the balanced out via the 2.5mm TRRS audio jack versus the weird box thingy that taps also into the ground signal from the 3.5mm TRS audio jack? Both are providing audio balanced out so what is the purpose of the additional ground signal? Did I misunderstand how it works?

For a "real" bal signal you need 5 pins ( see the 5 pins XLR or 2x3 XLR ) for;
+ & - right
+ & - left
And Ground

On 4 pins you miss the ground... I believe.

So 5 wires/signals out? How to wire 5 of them to IEMs? Each earphone piece only has 2 pins. Or it only works for headphones/cans? And what exactly in terms of audio quality will that be missing out?

The BAL OUT with the 5 wires is ONLY for if you want to connect the AK240 to a balanced AMP.  Not for balanced headphone.

I see. Thanks for the clarification.

Will a single link from  the balanced port via a 2.5 TRRS connector to balanced headphones or to a balanced headphone amp like the Ray Samual SR71B

be sufficient or do you need to get an additional link to the (ground)  in the headphone port
