Design & approach

Grado is a family-owned American audio company whose history spans cartridges and headphones. The company describes a progression from cartridge development to headphone design. That dual focus connects personal listening with the mechanical source at the beginning of a vinyl system.

Equipment in use

Grado SR325x headphones serve the venue’s private listening stations, paired with Technics decks and Leak electronics.

Inside the system

Project Audio’s installation combines Tannoy Westminster Royal-class towers and Super Tweeters with four TPI UC15G units, two beneath each Westminster. Tannoy Autograph Minis provide fill, with Luxman M-10X and 509Z electronics, FFA/NST amplification and DSP crossover and time alignment. Two Technics SL-1200G decks feed an Isonoe 420 rotary mixer. Separate listening stations use an SL-1210MK7, Leak Stereo 130 and Grado SR325x headphones. Townshend Seismic Isolators are used beneath the speaker stacks, linking the large-format loudspeaker arrangement with mechanical isolation.
