Naim Audio NPX TT External Power Supply The NPX TT is the dedicated external power supply for the NVC TT phono preamplifier. The NVC TT can receive power from a compatible Naim preamplifier (the NSC 222 or NAC 332) or from the NPX TT as a separate unit. The NPX TT is the more thorough approach: it isolates the phono stage's power supply entirely from the rest of the system, in its own chassis, with its own mains connection. A Power-Line Lite mains cable is included. A Micro USB socket is provided for firmware updates. No other connections are required beyond the proprietary link cable to the NVC TT.
