The 1500 WPC dual mono integrated amplifier is machined from solid bars of 6061-T6 aluminum by Vertec Tool in Colorado Springs. Vertec has been sculpting Rowland products for over 25-years. Vertec’s creativity and expertise can be felt in the Daemon’s precision weighted volume bezel. Mounted between two industrial grade bearings, the volume bezel provides exquisitely tactile access to a 99.5 dB range in 0.5 dB increments.For ultimate isolation, the digital and analog power supplies are completely separated and have individual local regulation at point of load. 6-layer Rogers ceramic circuit boards are used throughout.
