Hi Nick,
Glad you like the cables and the CD! I agree with you about the sound of Beolab Pentas, they are excellent speakers! Personally, I prefer the sound when the mid/treble panel in the centre of the left-hand speaker has been turned through 180 degrees, ie. so that both tweeters are on the inner edge. This gives the sound a little more crispness and clarity IMHO.
To do this, just prise off the lower grille gently with your fingernails and use a Posidrive screwdriver (mk.1's) or star/Torx bit (mk.2/3's) to remove the 6 screws holding the panel, turn it without removing the wires and re-fix the screws. Simples! 
Best regards,
Steve.
PS. For the record, I can't always promise to hand-deliver EVERYONE'S cables (eg. yesterday's shipments included Vietnam, USA, China, South Korea, France, Poland and Latvia, as well as a few more local ones!)
