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.

kharma cables

I only have personal experience regarding the Eclipse and the Coincident, but based on that experience plus the prevailing scuttlebut on the Valhalla, all the cables you mention are good choices at their price points. However, the prices of these cables are extremely disparate ($300 for the Coincident, $600 for the Eclipse, and $3300 for the Valhalla). Do you have a particular budget in mind? If cost is not an issue, I'd certainly recommennd demoing the Valhalla in your system. Another cable you might want to consider is the Silversmith Audio IC.
