Mains Cables

Following the recent threads concerning fuses and Mains optimization, I wanted to share one of my experimentation. Simple, easy to do and
respectful of all safety issues.

I noticed that the Naim supplied Mains cable were of relatively small gauge (1.5mm2 or 2.5 mm2 max). So why install dedicated spur(s) of higher gauge and still have a bottleneck at the end?

So I went to the local DIY store, buy 3x4mm2 Mains cables (standard and very cheap 3 Euros/m) and relevant plugs, and built me 3 "new" mains cables. (remark that you could also use 3x6mm2 cables, but they are very difficult to fit into the plugs)

I connect this to my CDSII/XPS (still burning in), HiCap and 180.
I also take the opportunity to rewire the 6 way plug, the one sold by Naim Germany which is endorsed by Naim Audio (?) and which have only 1.5mm2 cables fitted.

Results?
Well, bass goes deeper, treble are more refined, everything is more defined.
The most notable enhancement is with the dynamics. The system swings!
Drums for example hit very hard and even with my LS3/5 speaker, if I raise the volume a bit, I can feel the bass drums physically (to some extent as
the 3/5s do what they can in this field!).

I think this question of Naim Mains cable have aldready been discussed on this forum, but it would interesting to know what people are using,
what they have tried and what are everyone opinions/experimentations on the subject.

My 3 DIY cables cost me around 20 Euros (20 USD/13 GBP) so it is not a money issue.
