WHY ??? This Will be very stupid from them !?

Yes, and it will have Wifi, so we can also stream Music and the offline download capacity will be huge, but the expected Price of 2400 Dollar tempers the excitement, I guess I will wat for the Sony ZX1 wich will come at a comparable moderate Price of 550 Dollar, the latter will come with Android 4.1
I expect the competition will follow the Wifi /Android path , so it will be an exciting year to come.

Jude....you should really check out the Sony NW-ZX1. It even streams hi-rez files from wireless hard drive and run on full Andriod 4.1. It sounds sublime with my JH13pro and noticeably better than my modded AK100. The only downside is the 128GB onboard memory. The UI on the Sony is neck to neck with Apple iPod. It even features a "search" function to look up songs or albums in your library.
Well, like Vinnie said here, there is much more involved in making a real a "real" line-out:
[COLOR=0000CD]" Well, if you are referring to the RWAK100-S / 120-S, there is more being done than re-routing the output to bypass the head amp. The d/a's are changed to WM8741. They are configured to run in "hardware mode" (not software mode), so there is no longer volume control of the dac, period. The d/a's are configured to use their internal minimal phase filter option that the 8741 offers (not a linear phase filter, so there is no 'pre-ringing' of the output signal - so it sounds much more natural). In the case of the 120-B, a true balanced line-out is send to a new output jack (the SE out of the AK120-S also goes to a new jack). So there was more to it than just re-rounting to bypass the headphone output. But as for your question:[/COLOR]
[COLOR=0000CD]As far as the AK240 line out implementation, unless there is some internal switching going on (solid state or relay based) that actually bypasses the headphone amp, AND somehow they configure the dac to bypass the input from the digital volume control at the same time, then I suspect that it really is a "pseudo line out." Meaning the volume is set to max and locked via software, and the signal is still going through the headphone output stage. I'm sure this will be clarified by A&K at some point. I'll be taking a peek to see what is going on. [/COLOR]
[COLOR=0000CD]A true, fixed-level line out is one that follows the d/a chip's analog output stage (and there is not volume control in the path - not even a maxed-out one). Line-out can typically drive as low as a 5k load without strain, but not low impedance of headphones (like 600 ohm, 100, or 32 ohm, as a headphone stage is needed to provide enough current for lower impedance).

That sounds to me that the volume control would end up chopping bits off anywhere it's below max level?
Better would be max bits out and attenuate via the analog output stage but that would require a micro stepped attenuator or something more sophisticated.
Question of the day : does the AK240 chop bits off at the volume control or more elegant implementation like the Meridians?
I'm popping out for a few weeks, I'll come back when there's an actual player talk about...
I've read this numerous times but don't think that's correct. Streaming requires a DNLA server that only a few drives have at appropriately higher pricing. My experience with wireless streaming will also limit you away from doing so at the highest res.Yes it should work but you likely need more than a WIFI drive and may not be able to do 24/192 etc.
I don't know but it seems from the menu bellow that they have a "LO option" available.
Question, is "how well" is that "LO Option" implemented. Is it only a matter of setting volume to MAX :mad: or does it involve [COLOR=0000CD]some internal switching (solid state or relay based) that actually bypasses the headphone amp, AND somehow configure the dac to bypass the input from the digital volume control at the same time ? [/COLOR]
No, this do not tell me if there is some electronic inside the "block" or not ? this do not explain me why I need a "block" rather than just a special splitting cables !
