Interesting,  i have no issues with SQ on ALC889.

Personally, I have never had issues with the optical on any of my MBP's.

The E12 can, not sure about the others.

Awesome thanks. I was actually looking at this one, is the one you linked similar (no image).   http://www.digikey.com/product-detail/en/262120/ACX2005-ND/3088390   What is the turn around time for digikey? They seem to have everything needed.   Ordered, stoked, can't wait. 

Thinking of trying MMCX on my next mod. Does anyone know where to get MMCX female panel mount/bulkheads as well as male connections? Not having much luck on ebay.

Cool, I will go with the Mogami then.

Hey Casper,   How flexible is that Canare L-4E6S? 

They are on Amazon as well.   http://www.amazon.ca/Beyerdynamic-Custom-One-Pro-Black/dp/B008XEYT48/ref=sr_1_1?ie=UTF8&qid=1391232520&sr=8-1&keywords=beyerdynamic+custom+one+pro

Are you using cases? I have a pair of crappy Sennheiser's that are going on 7 years old that I have treated like absolute crap but they are still going strong.

Depends... After Effects will quickly yoink 16 of my 32. Sometimes more when rendering. If you are using Adobe products I would drop the RAM and pick up an Nvidia card with as many cuda cores as you can, scrubbing real time makes a difference in productivity rather than doing RAM previews all...

Nice! I just picked it up in ALAC. Can you donate after the fact?

Do you have a specific budget? The E12 is definitely more than enough for 990/250's. The battery life is pretty amazing too IMO.

This is starting to get reaaaal huge! Keep up the good work.

Other than Mini-Jack(1/8" / 3.5mm)? Yes there are many.

To answer your OP. Yes, you can mod any headphone into the connection you choose terminated at the can.
