NVS-211PSE Tube Power Amplifier


Our just introduced NVS-211PSE embodies everything Navison engineers have learned in designing our amazing amplifiers and preamplifiers to date. This unique circuit design allows Two 211 Triode's to run in parallel maintaining the purity of our single ended designs and raising the output power to a formidable 80 watts per pairs. The very same 6SL7 & 6V6 input/driver stage used in the NVS-211PSE has been doubled up to support this powerhouse Class A amplifier and maintain the huge soundstage, sweet tone, and authoritative presentation of its little brother. Still we were not prepared for the increase in performance this Special Edition has brought forward. Since our original goal was to create an amplifier that could drive the most demanding speakers while still maintaining the superb sonic presentation of the NVS-211PSE. It was with great excitement that the Navison team discovered this new amp had gone so much further. The NVS-211PSE has a majestic quality that brings recorded music to life and the soundstage that is so palpable it is easy to forget you are listening to a home music system. This is our statement amplifier and we challenge our competition to compare fit, finish, parts quality and sonic performance at any price. In addition we invite you to listen to music again the way it should be heard the natural sound way.
