Sennheiser 650 Headphone Cable Upgrade


I just purchased a pair of Sennheiser 650 headphones. I was debating on upgrading the headphone cable. For all 650 owners, did you upgrade the cable and was it 'worth' it? I'm trying to stay under $300 if I decide to purchase an upgraded cable. Strictly casual listening through an iPod or my Marantz receiver.

Also, what cable manufacturers do you recommend (i.e. ALO Green Line, Cardas)? I'm sure there are others, but that's just what I found. Any other recommendations would be greatly appreciated.

ANyone tried any cable upgrades with Sennheiser Momentum phones? Any results?

Thanks.

With my budget, I think this is my best bet.
Well, I ended up purchasing a USED Stefan Audio w/ 1/4" plug headphone cable for a great price. I typically will only listen through my Marantz receiver, but I may also want to plug it directly into an iPod. With that being said, will the Sennheiser adapter suffice or would that degrade the sound?
The Stefan Audio Art is a very nice cable for the Sennheiser 650. With the limited music quality to be had directly from an iPod, I do not think you will hear a decrease with the adapter.
