Need interconnect between Nagra pre to power amp

I would go for the Valhalla. It is truly a wonderfully neutral cable that has no weakness.

I think you should try the Argento VDM, it will make the other cabls you mentioned seem very overpriced. I use it between my 300B power amps and the Audio Aero Capitol 24/192. Picking the Argento over the Nordost and Cardas Golden Cross was the easiest choise I have made during my time in this wierd hobby.
The Argento is not exactly cheap (1600 euro for 1 meter XLR-XLR) but simply much better.
