Sensibly-priced mains cable upgrades (<£200/€300)?

[McMo]

Just sprung for a used D200 and loving the sound from my Squeezebox Touch (digital coax) and LP12 / Dynavector DV10X5 into Dynaudio Contour 1.8 MkII (without SAM).

I need to buy a new power cable because my D200 came with a UK power plug which I'm using via a UK - Schuko adaptor for now (I'm in Portugal) and I thought I could afford better than chopping off the 3-pin and substituting a generic Schuko. 

Seems lots of you guys spring mega-bucks on cables but I'm not in that league.  I'm after a decent power cable with a Schuko mains connector and an IEC that fits under the D200 cable cover.  Preferably one that doesn't rob the Dev of the things it does so well.

Thinking along the lines of Chord Power Chord, Wireworld Stratus but have no experience nor realistic chances of demoing.  Budget up to £200 sterling or €300 euros.

Any thoughts?

Obrigado e boa noite

Hi, I'm using a 3-meter Audioquest NRG-X3 bought from amazon.de for 145 Euro; it fits under the cover of a D-250; I haven't done a detailed comparison with the stock cord (which is too short for my system in it's new location), but I'm fairly sure it hasn't harmed the sound at all.

Hi,
I'm getting very good results with Fisch Audiotechnik P5. 
They also offer the P1 which is quite a good cable, priced around 250€.
Will also fit under the Devialet's cover if you don't go for the Oyaide plugs but the standard ones.
