Tried peeking at accessoryJack t see if they had the new DAPs on pre-order and got Internal server error HTTP500

Dev team member interview is up.  Highly recommended reading if you understand Japanese.

Can you do us all the favor and, translate please ?

 
Google chrome translate, works for me.
 
....although, translation into English, leaves a lot to be desired !
 
"Constraints to the development of the ZX models"
 
"Lets make the Walkman, in pursuit of true high quality sound" - WM1
 
"The jump up from the ZX series is large".

I'll just summarise a few points from the interview which I personally found interesting and noteworthy:
* There were constraints in developing the ZX series, which they didn't have in the WM series and was allowed to go "all out" for sound quality, this is part of the reason why they decided on the new naming scheme
* The S-Master HX is completely new in the WM series and was redesigned from the chip level up and is newly fabricated. As they said if people were accusing them of cost saving in using such a design they would've just picked an off the shelf ready made chip which would've been much cheaper.
* Their arguments against currently popular dual DAC implementation is that because unlike their approach of full digital pathway (until final output) is that it is done as a way to eliminate cross talk between the L and R channel when the signal is traveling in analogue form down the signal pathway, but because S-Master is fully digital they have no such concern (my note: actually sounds pretty legit from signal engineering POV)
* The special 4.4mm jack used by the WM walkman is developed by Nippon DICS - it has two contact points (top and bottom) unlike normal jacks for the plug such that it has the advantage of reducing connection resistance as well as increasing reliablity.
* They changed the rear panel (which acts as the ground for all the electronics) from stainless steel to a Corson copper alloy, citing the better conductivity of the alloy for increased sonic performance
* The capacitor capacity is increased from 350mF to 500mF for better stability during discharge
* They developed a new condenser and the number of condensers used is different between the 1A and 1Z, thus contributing to the sound difference
* They build a DC regulator into the unit to purify the output voltage and remove noise
* They kept the two clock setup (44.1kHz and 48kHz) - but used a bigger crystal/chip for better stability
* The SE output and the Balance output audio circuitry sits on different sides of the PCB board to they don't interfere with each other
* software UI is redesigned from ground up, with the player interface sitting as the home page and everything else pivots from there
* 5 new DSHEE HX settings - standard/female vocal/male vocal/percussion/strings
* 10 band EQ, 20 steps adjustment with 0.5dB per step
* 120 step volume adjustment, twice that of ZX2, plus normal/high gain setting
* the protruding "ear" at the top of the unit for the headphone jacks was designed to accomodate the BT antenna instead of making the unit taller.
* they made the remote because they expect the weight of the unit means a lot of people will be having the unit in a bag instead of a pocket/carried

From the JP homepage, the review with music producer gives this comments:

If ZX2 = Full HD vision,
WM1A = 4K
WM1Z = 8K

Has anyone compared the Wm1 audio to the ZX2 when using sensitive multiple BA's IEM?

The Wm1 is actually priced cheaper in Australia than the ZX2, which I found surprising, especially if the wm1 sounds better with IEM's.
