@n_brio - I have not used these cables, but I did take a look at their website and from whay they have published there, they look to be very competent cables, based on...
- the type of wire and gauge they use - i.e. silver (for interconencts)
- the type of Insulation dielectric - Air (in reality very close to air)
- cable geometry - to mitigate induced noise
From their site:
We have combined the pure silver conductors and air insulation in a unique cable construction, which is based on tubes.
And they look to be reasonably priced, considering they are "Hand Made"
Having built many cables myself, my latest recipe uses a very similar approach they yields stunning results.
- improved clarity
- significantly better.finer details
- more expansive image
- better low frequncy textures
So based on that - I think you should seriously consider giving them a try
Hope that helps - Steve
