For over 35 years, Dan D'Agostino has been designing some of the best audio equipment in the industry, from amps and preamps to CD players and loudspeakers. The new Relentless Preamplifer performs one of the most critical jobs in the audio signal chain with no compromises on design or quality. Weighing in at 132 pounds, the Relentless preamp processes the low-voltage signal directly from the source before sending it to the power amplifier and finally the loudspeakers. The three-chassis design isolates that low signal from electromagnetic interference for superior sound quality, and the dual-volume arrangement allows for controlling up to two sources separately in two "zones" or rooms. A machined aluminum and copper-clad remote uses Bluetooth 5.0 tech and a touchpad to control the preamps functions. An optional Digital Streaming Module allows for digital sources and streaming capability, along with an iOS or Android companion app.
