Dodd - GR - dB - Mach2
Patricia Barber is a secret guilty passion of mine, so when I heard the sound of her singing "The Quality of Mercy" from Café Blue coming from room 2024 in the Marriott Tower, I had to go in. The system featured GR Super V open-baffle speakers ($2495/pair as a kit), which were designed by Danny Richie, who had done some of the crossover design on the well-regarded Usher Be718 speaker. Amplifiers were Dodd Audio tube monoblocks, preamp Dodd's battery-powered tube-buffered passive design. the D/A processor was the Tranquility from dB Audio Labs. This $2395 processor was being fed data via USB from a Mac mini modded by Mach2 Music. For $1495, Mach2 supplies a turnkey Mac mini fitted with a 40GB solid-state drive and 4GB of RAM, as well as a 320GB external drive for data storage and the playback software of your choice. The mini's Snow Leopard operating system has been slimmed-down by removing anything that would otherwise interfere with the task of streaming music data from the USB port.
