DIY mains cable...

[BlueMax]

There are some pretty looking cables out there.

Make sure to find out and compare factors such as type/coverage of screening, core dia, insulation materials and cable geometry.

I just ordered an Opal-F to use with my CDX, I'm currently using a Campaign Audio Design conqueror~mi. Will report back later.

It's a stonker the Opus-F! £79 these days, so a bit expensive, but it's filter does a great job at increasing resolution from a CD player. CD players seem to be about the most sensitive to mains born rubbish. I gave my previous cable away, pronto!
