The tube like sound is complete, airy, dynamic, lively, and incredibly musical. The purity of human voices and accuracy of instruments is breathtaking. The Roma37DC with its 450W each channel, provides a fast, dynamic presentation without the dryness and sterility of other Class D designs. This is due to the 6DJ8 tube input stage and the natural sound of the class D audio module. Resolution, transparency and detailed sound are above and beyond that which one would expect from an amplifier. The MM phono stage combines exceptional sound quality and unique features.
