This is going to be a bedside rig so the iPod will be the source.
For headphone cables I was looking at/considering these http://www.head-fi.org/t/577528/hifiman-series-moon-audio-silver-dragon-v3-cable
Do you have the 10SE? If so, how do you like the DAC?
@jtiis, As stated, you will not be able to connect your ipod to the 10SE without a device which extracts the digital signal off it - then on to the 10SE via coax SPIDIF (or optical).
The ipure is by far the best value imo. It gives you the option of SPIDIF optical or Coaxial ( and it's own dac if you ever want to use it with just an amp - ie not the 10SE)
You will need a coaxial cable or a toslink optical cable depending on your choice - typically coax is the prefered option but a good glass toslink should give you on par quality from my experiance.
I can recommend Lifatec Silflex glass optical cables - excellent value and performance.
For coax I would recommend Black Cat Veloce 123 - again great value & performance for the money. I have had both these cables.
A cheaper optical is the 1300 core plastic sys-concept which I have not tried yet but reviews well.
Pick your choice between the DIR9001 & WM8805, not alot between them apart form the 96khz limit on DIR9001 which wouldn't worry you using the ipod as a transport.
With Headphone cables, they need to be terminated in a 4 pin xlr plug so you can use the 10SE balanced. If you want a silver cable the TWag v2 from Whiplash is really good imo (my hd650's have it) and the Moon Audio Silver Dragon v3 is supposed to be also excellent (haven't heard it yet). Or alternativley a DIY'er could build you something.
If you want to use the stock cable, it will need to be re-terminated with the 4 pin xlr plug by either a cable company, DIY'er or your self with the kit Audio_gd offer. (you will need to be able to do basic soldering)
Hope this help, If you need more help which is off topic, shoot me a PM but the 10SE is insane value for a completely balanced rig (minus transport).
