There is one historical precedent, though not audio. One of the methods used in World War II to separate isotopes for the Manhattan Project involved cyclotrons, accelerators (atom smashers then) each with two huge, heavy electromagnets. You can see small ones in the back rooms of PET scan facilities. The all out war effort had caused a major nationwide shortage of copper for non essential (no substitute available) uses. Well, we are talking about the government and the US Mint had many tons of pure silver on hand, so...
The interesting part is that when copper became available, the silver was returned. Copper was the material preferred by the project engineers. The very small weight savings was of no consequence and the conductivity difference was minor at best. NO one claimed that the silver magnets conferred some superior quality to the generated fields, so practicality ruled. The engineers were obviously not modern audiophile consumers.
