2) What's the best type of insulation to use that won't hinder the expansion and collapsing of the magnetic field that forms around the wire as the current goes back and forth in the wire while the music plays and what scientific tests support your claim this is the best speaker wire insulation?

Quick recap:

The insulation cannot prevent or impede the magnetic field B from forming around the conductor. It's no secret how electric and magnetic fields form around the conductor, go back to Heaviside and Poynting who developed the theory a long time ago for Poynting vector and E and B fields for electrical circuit. This is the concept that the energy in an electric circuit lies entirely outside of the conductor. The energy of the electrical signal is contained in the E and B fields.

The electric field E and magnetic field B are orthogonal to each other AND to the direction of electron motion. The insulation is the dielectric material and the dielectric constant of the insulation should be close to 1.0. Also, note the current doesn't go back and forth, only the free electrons do. Current is a calculated number and has no direction, it's a scalar quantity.
