I'm no expert in chemistry, but I'm almost entirely certain that oxygen in the cable has absolutely no effect on oxidation. Copper most commonly oxidizes when exposed to air and moisture; even your purest of copper wire would form a patina if exposed to the elements. Removing oxygen impurities in the wire would have absolutely no bearing on oxidation, and even the term 'oxidation' does not automatically imply oxygen has any involvement in the chemical process.

The chemical reaction with oxygen is the definition of oxidation.

Not quite.

Oxidation is caused by exposure to oxygen, yet removing the oxygen won't help prevent oxidation? I would like to see some evidence please.
 
Evidently "Oxygen-free pure copper can be alloyed with phosphorus to better withstand oxidizing conditions", that's interesting as well:

You're not removing giant air bubbles from a cable, you're removing microscopic and even molecular/atomic-scale impurities. Surfaces still exposed to the elements will oxidize all the same, whether 99.9% or 99.99999% pure copper.

And what is that minuscule amount of oxidation going to do?  Increase impedance by a zillionth of an ohm if you're unlucky?  Its not an issue.  At least not in the wire.  If your connectors are made out of copper then OFC would mean you'd have have to clean them slightly less often, but most people use gold since you'll never have to clean it unless you also happen to be immortal.

That is why I prefer gold-plated connectors and oxygen-free cables, YMMV.
 
I will pass on even "minuscule" oxidation, if it's possible to avoid it.

Splended sounding for all my mentioned cans. Zero hiss, BTW (as I've been reading some of the comments).

First time ever that I've not had to EQ my SE530's in my DAP ... the level 1 bass setting is just right for me with the SE530's and if it's a particularly lean track (low end) then the level 2 is occasionally used.

After a bit of time with the Arrow, I can still say it's something that will remain in my Collectors Section(tm). 
 
Sweet bit of gear for sure.

Got this today (#2821). This thing serious kicks ass. Right out of the box. I love the bass setting, my DT 770 Premium really need some songs on level 2 Bass. Corda Headsix wasn't able to get this as i wanted and the FiiO E5 was just a joke. I don't regret the money and the long waiting time

When did you get the shipped notice and where are you located. Ive gotta be gettin close

 

[lazysleepyboi]

since you're living in the USA, it should be coming by USPS. I just received mine today, and i'm really enjoying the whole music experience. It's really making my headphones shine with whatever i throw at them. Anyways, i was number 2866, so just be patient, yours should be coming this week. btw, i live in california

 

[Dabylpmis]

shipped notice was 22.12. but post stamp was from 03.01. Somethings messed up there

 

[Golden Monkey]

Mine shipped 12/21, still waiting in California...god I hate the USPS...

It could be that the post office had a lot of backlog, and was on holiday for a week or so. The item couldn't be stamped until much later.

@kingpage, I couldn't help noticing your signature and tried a hearing test myself.  My range in both ears is about 20Hz to 17,250Hz.  At 19,000Hz you must be part bat! 

 

 

[Mediaogre]

I hate you guys. 

 Where in the hell's my old-man-with-hand-cupped-to-ear emoticon?
