Speaker cable for ATC SCM40 passives

Discussion in 'audio' started by K'ford Pikelet, May 23, 2023.

  1. Hello everyone. I’d be grateful if anyone could recommend speaker cable for for my ATC scm40s. I have Teddy Pardo MB100 power amps and currently use Tellerium Q black.
    Many thanks Paul

    Whats wrong with your TQB then ?
    The EWA something is original TQ design but reported better, no experience myself.
    Other cables, your in a minefield.

    I have ATC SCM19s paired with Avondale modified Naim amps and use Witch Hat Phantom cables, they really are excellent.
    Another post here also mentions the Van Damme cables, I started off with them, and they are great cables for the money, however the Phantom cables, in my system were a huge step up though.

    no need to spend loads but make sure it has about 2mm sq of copper, witchhat phantom a solid reccomendation, atlas hyper also.

    Where's the fun in that when there are so many more cables to discuss at various price points. :D

    ATC themselves say:

    “4. What cable do you recommend for loudspeaker and line-level connections?

    For loudspeaker cables we recommend using oxygen free multi-stranded copper cables., For lengths under 5 metres we recommend using 2.5mm2, and for longer cables up to 10m we recommend using 4mm2.

    For line level cables we suggest good quality oxygen free multi-strand copper cable. Ideally bare silver-plated copper with less than 100pF/metre capacitance from core to screen.”

    Sommer Meridian would be my recommendation for an easy flexible cable, good quality, easy to terminate, and cost effective. I think it's around £5/m for 4mm. I've seen in it plenty of studios, and for fixed installation. They also do a tougher but less flexible version for fixed installs as it pulls through wall cavities easier, but i'd avoid that for domestic purposes and stick with the flexible softer stuff.

    This stuff:

    A bit more expensive than I remember, pushing £7/m, but there we are, inflation and whatnot.

    Basic 500 strand speaker cables is what we mostly use with passive SCM40's -

    If I've one length 4m and the other 7m ... I'm guessing they'd need to be matched in thickness so I'd be best off with the 4mm but does anyone know if the lengths should actually be matched leaving a lot of spare unused cable on one side?

    With the Van Damme there are various colours, the one linked above

    but also blue and black ... is there any difference between them?

    ATC gives some advice about the effect of different lengths of cables on damping factor and loss at the end of their data sheet on remote amp pack mounting. I’d just use the heaviest cable I could in whatever lengths reached the speakers neatly, and avoid coils of unused cable which I think was a naim thing for particular reasons.

    What do you expect from changing from your current cables?

    I used Mogami W3103 and later W3104 (can be a pig to connect correctly) with SCM19v2.

    It makes zero difference to match the lengths

    The blue and black have a sturdier thicker jacket for studio use

    Agreed. I have used cables of different lengths for a long time now. The manufacturer said it makes no difference in typical domestic cable runs
