Until I had not tried Nordost Brahma mains cable (on mbl 7006) I did not believe that mains cable makes a difference. I said that they cannot possibly make a difference after all these miles of lousy cable all the way from the power-station, well from the transformer. However, they do...
Therefore, I will most likely DIY one.
One DIY project: TNT TTS
And maybe more scientific approach: VH Audio
And another: Scoobidoo
Intersesting it is that no shielding is used (to achieve lower capacitance) - also Brahma does not have it.
