The VAC Master 300 iQ Musicbloc builds on the design of VAC's flagship Statement 452 amplifier, featuring the same audio circuit topology, hand-wired audio pathways, and a similar internal layout. It offers a natural choice for high-end installations by delivering the same sound character with just 1.5 dB less maximum output. The amplifier can be configured for 160 watts per channel stereo or dedicated 300+ watt mono operation via three switches on the back panel. It uses fully balanced active audio circuitry from input to output, with balancing input transformers for single-ended inputs. The input and driver circuits are direct coupled and use highly linear low mu octal triodes operated in full Class A1. The output stage employs KT88 beam power kinkless tetrodes, with bias controlled automatically and continuously by VAC's patented iQ Intelligent Continuous Automatic Bias System, ensuring plug-and-play reliability and automatic notification for tube replacement. The amplifier uses premium output transformers, resistors, capacitors, and connectors, combined to produce vivid, palpable music reproduction that brings listeners closer to the artists and performances. It is designed and handcrafted in Sarasota, Florida, USA.
