The Astell & Kern AK240

General question for anyone in the know..
 
May be stupid and i think i know the answer but just want to be sure. 
 
In regards to balanced cable. I assume the cable needs to be balanced from AK240 output to the earpiece of the IEM and that an balanced out adaptor feeding a single ended cable will not give a balanced result. Is that correct ?

You cannot use a single-ended cable and terminate to balance TRRS plug as you would instantly short circuit your 240

If I was paying 2.5k for a dap, I wouldn't complain about their case prices and all but I rather not to talk more about as I don't want to get banned or something

You're right, since I've already drank the Kool-Aid (or I wouldn't be here in the first place). It's just that reality creeps in sometimes with this hobby. If it were a point and shoot camera case, with the same features and materials, it would probably cost 20.00 dollars. MHO

Judging the linearity of the signal that the AK240 brings to a Shure SE846 i can't help thinking that this is snake oil to the nth.

I would expect that the most expensive dap ever could be able to feed properly low impedance balanced armature iems. Truth to the matter is that an iPhone 5s do better in that regard. Not ti mention an iBasso DX100.

AK advertises the output impedance so snake oil it isn't.  That plot looks like the single ended output.  Correct?

Try the SE846 with an iBasso DX100 and report back :wink:

I would try but I'm in love with the :two_hearts:240:two_hearts: Just put in an order on my second one which hopefully will be here by the 1st of the month :wink:

If that's a balanced out curve, normal out will be twice as good and vice versa. Also be aware that it's an expanded curve. That's effectively a deviation of less than 3.5db overall on an earphone that drops to below 5 ohms in ranges.
 
Here's what I posted in the AK240 thread a few months back, predicting the se846 response with an AK120 so more deviation than here but describing the same sort of curve as above. http://www.head-fi.org/t/699429/what-difference-should-i-expect-ak120-rwak120-se846
 
I don't look at the graph in this thread as any issue at all with the AK240 which has a very good output impedance spec but with the earphone which has a ridiculously low impedance for a new design. That said, it's voicing may actually be included in it's impedance curve and if it sounds good in a combo, it is. It's just that the impedance of a se846 lends itself for inconsistency of response to even very well designed DAPs. I believe the TF10 had a bit of that as well and got more V shaped with ultra low output impedance devices.
