Is optical cable meant to be bent? Does it have ant impact on the sound quality?
In other news, for those that are interested, I can try a test to see if QP1R to Mojo vs QP1R to AK120 to Mojo sounds the same, that will prove surely if player EQ / DAC plays a part in what is received by an outboard DAC or not (on the assumption the AK can both receive and transmit optical at the same time)
Interested?

That sounds scary. Imagine if you have a tight-fitting ciem in your ears. Better unplug real quick.
Also, the big buttons means you could have something similar happening from inside your pocket or bag, in which case it's probably safest to yank it out of the ear as quickly as possible without damaging the eardrum. Scary stuff! A "lock" function would be nice.
One sounds better than the other.

It would be interesting but I'm not sure it would prove a positive as the ak120 could have a pass through circuit when receiving a digital audio input as it doesn't need any codes or anything for that (think of it like a tape loop in an ideal stereo)
My head hurts
Sorry...
I'll try to write a concise summary with analogies here...
Lets go back to analogue and vinyl, the sound information is created by the physical groove on the record right? so the depth, width and shape of the groove itself relate DIRECTLY to the sound you are reproducing.
We can visualise a digital PCM stream as being equivalent to that and the DAC being the stylus with the DAC or Stylus feeding the audio to our amplifier and then headphones or speakers.
We're all in agreement there I think with a perfect signal, DAC/turntable and amp everything would sound the same with the same speakers or headphones.
What I have been trying to explain in earlier posts is that the digital file itself stores that PCM stream so the file has to be read and turned into that PCM stream, we do not start with the vinyl, we start with a digital description of the vinyl that the DAP has to turn into the model of the vinyl (of course the benefit of this is that you can play and copy the original as many times as you want with no degradation of quality).
Bringing it back to physical terms we have the file to print the vinyl on a 3D printer.
Interpreting this is where different transports COULD alter the signal (and my phone definitely does as the change the volume digitally you have to change the PCM stream) - do I personally think that there is going to be a really noticeable difference? Not really, I think that it will be the least noticeable part of the chain (way behind DAC, Amp, Headphone and environment), but the question that triggered this whole discussion was whether it could make a difference or was it always perfect because digital = digital.
Now in Duncan's test if we get 2 different sounds it proves that the AK is altering the signal - but if it does not NOTICEABLY change the sound it could be because there is no processing going on or that it is minimal or very similar BUT it could be bypassing the AK software altogether and outputting the PCM feed that it receives straight out (like tape loops used to try to on old school amps).
I hope that makes sense - if there are specific questions PM me - but I'm not not going to flood the thread any more
