Best power cord for Devialet

[BoyScout]

I have had comparisons over the years but not too many with Devialet. At the moment I have also Voima2 in test and also some Shunyata cables but not final results yet. I believe there is no need to change away from Voima1.

Voima1 was easy to buy because I didn't find any weaknesses in the sound.

Any additional thoughts after comparing Voima 1 and 2 with which Shunyatas?

I´m waiting for that thoughts too...
Graditech site has a huge promotion for Voima 1 to Devialet, but they´re the factory.
