As a matter of fact, there is. Try Mundorf copper, silver or silver/gold foil (air-core) inductors. Silver is quite a bit more expensive and they're available in 10AWG. see: http://www.hificollective.co.uk/components/mundorf_foilcoils.html
On good sounding inductors
I am thinking of improving the passive crossover of my Apogee. I had designed the passive crossover of my modified Apogee Fullrange myself, with 1st order 6 db/octave ccrossed at 400 HZ. I used the Alpha Core Goertz inductors. Is there any better sounding inductor than the Goertz? Thanks.
