Denon is a Japanese electronics company, but it was Frederick Whitney Horn, an American visionary and entrepreneur, who started the company in 1910. Denon produced the first cylinder discs in Japan and players to play them.
@anodigital they were the only ones of that caliber. My other headphones are the B&O H9s, Shure 535s and Symphony Ones. Leagues ahead of any of those. Not double the quality (being double the price), but they're amazing.
