NuForce USB Impulse Cable for uDac

Can anyone please help me find a location within the EU where I can buy these cables to go from my pc to my uDac? I live in Denmark and delivery/customs/import are prohibitive. Alternatively, can anyone suggest an alternative? I am looking for an improvement on stock usb cables, but am not in the market for anything top end. Budget would therefore be around 50 euros max. for 0.5m. 

I use my uDac to feed mostly flac and 320 mp3 to my old-ish NAD amp. I sometimes use it with my re0 depending on what I am doing. 

Also, are the Chord Crimson rca interconnects good value? Or anything better in a similar price range (approx. 50€)? 

Thank you in advance 

Thanks for getting back to me. I had read about the Ultraviolet - seems to get rave reviews just about everywhere. Do you have a link where one can get this cheap in the US? (sorry, but no real idea about US sites cos of prices, etc.). I know someone who might be willing to help me out though, regarding shipping. 

From your response, I am guessing that perhaps the uDac 2 might benefit from a premium USB cable? I hear there is a significant improvement in doing the upgrade. Or are you just referring to that (price/quality) level of equipment in general? 

Also, do you have any opinion on the stereo interconnects? I have read much about Blue Jeans Cables within my price range. Thoughts would be appreciated. 

Jury is still out on the premium USB cable after reading lots of back and forth about it - I guess the only way to really know is try it out for myself, but will probably wait until funds permit. 

However, regarding the interconnects, I found http://markgrantcables.co.uk/ and in particular, a returned pair of 0.5m G1000HDs at clearance price, which have some amazing reviews (see product page). Since I have no shipping, customs, tax, import issues (as opposed to the BJC - non-EU company), I have given these a bang and am now awaiting the postman/woman. Also should mention that Mark, the guy behind these cables, is a pleasure to deal with, so also ended up getting some blue Van Damme speaker cable off him. 

Thank you all for your comments and suggestions
