The stock cable for the hd650 is 3m in length and is way to long for my desktop setup, is there any shorter (around 1m to 1.5m), high quality, low cost, aftermarket cables out there anyone can recomend?

(First post on head-fi) I have been using the asus stx sound card with a pair of sennheiser hd558 for about a year and soon hope to upgrade my headphones to the hd650's. Is it worth upgrading my dac/amp to something like the objective 2 dac/amp combo?
