    On these forums I read somewhere that on solid core cables you can run into induction and capacitance problems on longer runs. Does anyone know what sort of cable lengths will give rise to these problems?

    I intend to use some 2.5mm twin & earth (as favoured by Stereo Steve!) for my rears (around 6-7m) and possibly for running into the kitchen for an extra set of speakers (around 10-12m).

    Any help appreciated. :lease:

    I can't see there being any difference in those electrical charateristics between solid and stranded core.

    Eviljohn2 - thanks for the reply, although I'm not sure if you are answering with certainty or speculation :confused:

    Bump for corroboration or other views ...

    Speculation from a mind that studies physics/electronics :)

    The lengths you describe aren't particularly long anyway and I'd expect regular stranded shotgun cable to have the same problems.

    The only way to avoid capacitance/inductance is to use a braided design like some of the DIY Cat5 models.

    Thanks again :smashin: - that's telling me! :lesson: . I'm almost too embarassed to tell you I got an A level in Physics, some 22 years ago. :blush:

    At the end of the day, I just want to run some white cable to my rears (Kef eggs), which means along the skirting and up a wall where some of it will be seen. If I go for a smaller diameter like 1.5mm T&E will the sound be noticeably worse or different?

    :lease:

    I use solid core telephone cable (4 cores) for the feed to my bathroom speakers. The sound quality is superb so I can't see a problem with you using 1.5mm or 2mm cable.

    Fat Tony... Your local electrical wholesaler should be able to supply you stranded 2.5mm twin and earth... Not much more expensive and easier to work with...

    Have a look at http://sound.westhost.com/articles.htm in the cables section.

    I have run solid core cables for many years, they are good value for money but not every amp will like them.
