I see your point though.

Seriously Apple could easily make a hi-fi dap and put all these over-priced toys to shame. All Apple need to do is to improve their existing ipod classic line by implementing dual wolfsons, providing a clean LO and making it rockboxable. Of course throw in a 256GB CF there too. Now you have a dream dap which can last forever.

I would like a decent amp in my dream DAP, please.

haha agree. They'll just cater for the masses, and they don't really care about dual dacs or clean LO. Most people will never understand or justify the price we audiophiles pay for our gears...

 

And that's where AK comes in and milk us dry XD

THE biggest problem with all things Apple is not the players, it's iTunes, and the fact like that, like SONY, they won't let you use your own files with external memory cards.

iTunes is probably the most hated piece of software ever by myself. My hats off to those who have made rockbox available so I will never be tormented by iTunes again. I recently loaded more than 230gb's of flac's to my 256GB CF and you could imagine how much I appreciated the rockbox.

Can I smack you for mentioning that nonsense............ wink.gif
But I soppse the arguement can be made the Sony of yesteryear would have actually done something amazingif the tech was there. Sony then would have taken the XPERIA Z1 and made a version where they removed the cell radio, toss in an S-master or 2, do some extra work to the internal circuitry and exen through in an bigger battery. But yeah. As for apple they are only interested in sheeple. There's no point in theorizing of them. The6 are a lost cause we'd all be better without.

I think that a very good AMP is not really possible INSIDE a DAP.  It looks like is it necessary to have a 2 box set-up in order to have a perfect AMP.  

 

There is Too little room & battery inside a DAP to allow for all the necessary circuits needed for a full specs AMP.

 

I have big hopes for the Cavalli next portable amp !  This is why I pay so much attention to the "Line-out" of the AK240 to know if it is a "real" line-out.

LOL, I have nothing against Sony, AK or others, meantime I am not a fanboy of anything either. If the AK240 smashes my current setup, I will donate the two grands without hesitation.

Every LO is supposed to be clean and I don't know why it can't be that way. When we mod the ipod video's, we lift the LOD pins (for R & L channels) off board and then fly the wires from dac directly to those pins, thus completely bypassing the board and internal amp. I am assuming in theory every LO shall be executed similarly, tho I am not a electrical engineer.

All,

 

If the AK240 proves to not have a true line-out, I will definitely look into offering that (single-ended, and balanced output options) as well

as whatever else I can do to get the most performance out of it.  I can only HOPE that a modded AK240 line out will sound as good

as the modded AK120 line out.  In the unlikely event that it sounds better, then I'll crap my pants in excitement!  :D   It would be a breakthrough.

What can make this happen?  It's all in the implementation of both the SW and HW.  

 

For those who want this to be an all-in-one player, I will also scope out the headphone output stage and see what I can do to maximize its potential.

 

And if there are any other things on your wish list, feel free to let me know.

I think you can get a powerful enough amp for IEMs inside a DAP.  I also believe the sound can be refined to get to the level of a high quality external amp (again, for IEMs) from a good DAP.  This also eliminates the need for a cable and the plugs/jacks to connect a DAP to an external amp, which is an advantage.  Whenever you can shorten the signal paths, eliminate connectors and plugs, etc. - this is a good thing IMHO.

 

But to drive something like Audeze LCD-3, Senn HD800, HiFiMan HE500, etc. with the authority of something like the ALO RX3 or RSA SR71B, you need more voltage swing than what the AK240 is rated for.  With a 3.7V battery, the only way this is done is with DC-DC converters on board to make larger voltage rails (e.g. +/- 10V).  The AK100/120 does this up to +/-3.3V I believe, and it's good, but not at the level of what something like the SR71B delivers, as it has higher voltage rails, much more capacitance on the rails to deliver higher output current, and does not need to use a DC-DC converter chips (which step up the voltage from the battery, but have much more limited output current compared to the battery).  Lower impedance voltage rails gives you things like bass that hits harder and tighter and more defined, more open sounding mids, a top end with better decay, etc.  Power supply implementation is HUGE because what you are feeding your headphones IS the power supply rails (modulated to mimic the input signal, with some level of distortion that is inevitable).  

 

And even if it could be done very well for an all-in-one, I find that different headphones sound best with different amps.  So having the flexibility to change amps does allow you to find one that sounds BEST with your DAP and headphones.  But if you happen to find the amp inside a DAP sounds best, then you are in good luck and can travel with one box (true "portable").  And if you want that all-in-one even though it is not as good as a separate amp, then you live with the compromise.  

 

Mark my words - Everything in audio design is something of a compromise, even "no-compromise" designs.  The fact that a designer's ears (and taste) can never be identical to that of his/her customer's is in and of itself a compromise to the customer. The harder and harder you look for absolute perfection, the more and more disappointed you will become.  You will hopefully learn later that you missed the point - the point being that is was supposed to be a fun and you should have been having fun listening to your music and getting more wrapped up in the listening, the discovering of new music, and sharing your findings with others and having fun.  

 

ok - we now return to your regularly scheduled thread.  :wink_face:

iTunes is great if you stick with standard Apple ecosystem. Can't believe people bash it while ok with the likes of AK, iBasso, Fiio aka horrible UX.

Best words I have read on this forum. Many thanks, Vinnie. :beerchug:
