Unlike them, Nuvistor tubes offer very high reliability, low microphony, low noise, consistency from batch to batch, small size, relatively low power consumption and great technical performance. The tube is made entirely out of metal and ceramic meaning making nuvistors requires specialist equipment but also means that Nuvistors are among the highest performing small signal tubes on the market with the results of which can be seen in the Musical Fidelity Nu-Vista range accross the board.
