You want to install Android apps? Get ZX1.

So this is possible with the ZX1 but not with the Calyx M? I've been having a closer look at the Calyx M, ZX1 and DX90 lately. 128GB would be totally fine for me. The only thing I am missing on the ZX1 is the missing USB/DAC functionality.

You can't have it all. There will never be a perfect dap to satisfy everyone in the world. It is more like, find your priorities, then take the best one for you.

Frankly, Gorilla Glass ain't that great, anyway.     Regardless of what the screen surface is made from, I would be inclined to immediately apply a screen protector, as i don't trust any screen material to resist scratches without protection.
 
For example:
 
http://www.head-fi.org/t/680853/sony-nwz-zx1-35th-walkman-anniversary-model/2400#post_10100841

 
Indeed. As soon as i get the precise screen measurements (assuming I get the Calxy M), I will be sending those measurements to Screenpatronus. They do a great job - most recently for my DX50. I still want glass underneath.
 

   
 
 
Maybe... but then again, perhaps the DX90 might have the Calyx-M licked, on the amplification side of the equation, so it may even the two devices out, in terms of overall single-box performance.

 
Those THD numbers are from the amplifier out (there being no separate line out, nor with those numbers is such really necessary). The single box solution is where I expect the Calyx M to excel. Again, time will tell.

If that's the thought process everyone's going by we certainly wont. Considering the purpose of this site, why is good audio (and features solely based around that alone) as far as we're going to push?
 
We've gotten this far; the ZX1, 240 and this among others are leaps and bounds over where things started as far as DAPs are concerned. No sense stopping now

That perfect DAP will end up costing more than an arm and a leg because we are so easy to satisfy.

I think the perfect DAP for me is HM-901, but I am still in the market to try different new offerings....bcos its fun...however, i cannot justify myself to get Calyx M "yet"
i am thinking i really dont need the big screen nor wifi...and the fact that this does not have a real line out...

Just an opinion

This line out question is interesting. Normally I am a fan also. It avoids double amplification on a DAP, allowing me to bypass the inexpensive and poorer quality internal amp with a superior external one. 
 
However, good home DACs usually have a gain stage. So long as this is clean, it increases the dynamic range for further amplification.
 
Calyx is suggesting that the M's headphone out, which has an electronic volume control, should be set to 100% to create a true line out of 1.25 Vrms. This is the THD that is produced:

Those are distortion numbers that are better than the so-called true line outs of other DAPs. It leads, I believe, to two conclusions. Firstly, the Calyx M may have the best line out yet on a DAP. Secondly, with 70mW+70mW @ 16Ohm output power, for IEMs there may be no reason to use an external amp at all. It is this second part that has me excited.

Cooperpwc,
Many thanks for your insightful comment. It is good to find out that this DAP measures well for iem.

 

[cooperpwc]

You are welcome and thanks for the kind words.

I was hoping that we would learn more about Calxy M design features from CES2014. (Actually the video was a bit of a wasted opportunity for Calyx.)

1. calyx The slide volume control is not as conventional as you might imagine. This is very special one.

      You don't have to worry about such a problem described in Headfi.org. That will never be happened with Calyx M
      
      
      

 
I am curious about this sliding volume control. Did anyone actually see the Calyx M at CES2014?

Hope so, but the 3,3 Ohm output impedance "may" be a problem With certain very low impédance IEM like my 15 ohm JH Roxane ?

It's only a theoretical problem for multi-BA IEMs - such as your Roxanne or my ES5. (My favourite IEMs are now all dynamic or single BA so it's not really on my list of concerns.)

You can always throw a Pico Slim into the mix to get <1 output impedance but I doubt that 3.3 ohms will actually skew the frequency curves on a a 16 ohm multi-BA IEMs. That's still a 5:1 ratio. Time will tell....

For anyone interested.... it may have been linked before but if not it may be of interest.

I heard from my friend that he had a chance to try the calyx m already, and the SQ is better than AK100; however, still inferior to HM901
 
anw, it's just from one's point of view, let's wait for other ideas

bmichels, apparently you have to wait till Krell, DCS, Opus or similar expensive gear makers issue a 10K DAP 4U 

 
i personally feel pretty much interested in Calyx M and how it compares to AK120. i was a happy user of RWAK100 and hope to get some improvement still. hopefully we will not have to wait eternally and soon we will hear first impressions.
