Jonathan Weiss doesn't do things the ordinary way. Nor does he follow the usual audio industry processes.

In 2006, Weiss founded Oswalds Mill Audio (OMA), manufacturer of a range of high-end loudspeakers and other products with exotic, vintage-inspired approaches and designs. Serious handcraft and bespoke materials, from solid hardwood enclosures to leather from luxury makers Hermès and Jean Rousseau, are behind OMA's upper-echelon pricing.
