    I am looking to install new cables for my surround setup 5.1 4 and would like some advice.

    I see that van damme blue is highly recommended and I also read a brief review on another forum that the clear van damme cable the LCOFC was even better.

    My longest run is about 20m will 2.5mm be good enough for this distance or do I need to use 4mm?

    Is the LCOFC better than the blue?

    Do I need to use different cables for my front L/C/R to my Atmos and rear surrounds? A retailer suggested that I should use different ie higher rated cables for the front, especially as the speakers I want to use have a ribbon tweeter.

    'Is the LCOFC better than the blue?' - No!

    We (TMF) stock and supply both. For the majority of installs we use the Blue Series cable as being a 'twin-axial' cable with a relatively small, round, cross section it is far easier to work with than the 'shotgun' style Hi-Fi cable, which only wants to bend in one direction.

    Speaker cables for Surrounds, Rears and Overheads tend to be delivering a 'frequency limited' signal and at lower output than the Front LCR - but do tend to be further away from the Amp (longer cable run) so on one hand less power may allow for thinner gauge cable vs. longer run wanting a heavier gauge cable!

    We tend to stick with the same cable for all channels and unless we are getting into very high powered amplification the 2x2.5mm cable does the trick for most installs.

    If someone wants to convince you to use more exotic cable ask them to supply you with some sample cables to try out in your system.

    Ribbon Tweeters are 'relatively' common theses days and do not require exotic loudspeaker cables to make them work.

    @Joe Fernand, thank you for the reply and useful information. I see Van Damme also do a black cable, is this of similar quality to the blue as it would look better than the blue cable when visible?

    Hi Razor

    The Black Series will sound no different to the Blue Series cables.

    In the VanDamme catalogue the Black Series is aimed at the 'touring' market so has a more durable outer jacket which makes it a little stiffer to work with - if you only have a short run of 'exposed' cable you can use a cable sock or any other type of 'sleeving' to ensure the exposed cable works with your decor.

    @Joe Fernand Thanks again. When you say a little stiffer to work with, will it be harder for my electrician to install/work with over the blue? Its mainly going to be run in ceiling voids and one or two walls will have to be chased, I noticed the diameter is larger than the blue.

    I would rather have the cable black to start with than sleeve it afterwards but if its a fair bit more hassle to to install I can stick to the blue.

    I can't imagine your electrician finding it too difficult to work with if you prefer the Black outer jacket.

    'Never installed my own cables before but can't be too hard, just strip them down and connect them up.' - take your time, ensure there is no excess 'bare' wire, no 'stray' ends and you you have correct polarity (+>+/->-) and will be good to go.
