Advice Needed (Speaker Cables & Interconnects)

If you contact Rick from Musicraft he'll sort you out with some good thick copper speaker cable, as for interconnects just use the cheapest you can find as there won't be any difference using more expensive ones.

You should visit your nearest/local hifi store and ask if you can try some cables, because what works in one system might not work in another.

I've always been happy with Chord and Atlas cables and still use them in my system.

+1 for Max's advice. If you have a cable that really changes the sound somehow, then something is wrong.

I would not recommend trying to use cables as tone controls at all, rather use the controls on the amp or get an equaliser.

I would imagine that your system sounds rather good as it is, but perhaps use the integrated amp to power the tweeters and the power amp to run the mid/bass drivers, in a bi-amp configuration.

IMHO cables and interconnects make very small if any difference to sound quality. Audition and then decide if you need to hear this for yourself. Save the money and buy some better speakers or lots of new music.
