World Class Designs - Exceptional Sound Quality - Outstanding Aesthetics

Audio Detail NV-08 Nuvistor Phono Stage

Product Description:

The new Audio Detail NV-08 Nuvistor phono stage, is a new 4 Nuvistor design with a further 4 triodes aimed at the user who loves the valve phono stage sound, but wishes for something slightly more special, offering a lower noise threshold, but with a fast and lively sound. Built by hand in Great Malvern, UK,  the NV-08 is all point to point wiring with the components mounted on a plated copper substrate and plus a traditional Point to Point 4 triode output stage. We have designed the output stage to use 6N6 double triodes, with the option of rolling to 6N1 or 6922, ECC88  variants.. We use paper in oil(PIO) and silver mica capacitors in the 2 stage passive filters.. With high quality German Audyn capacitors in the output.

What is a Nuvistor - Nuvistors are special valves designed in the late 1950's with the aim of combating  the rise of transistors within electronics..They are particularly good at VHF frequencies and are as small as possible(smaller than a thimble).. This means they are a lower noise valve, running at a lower voltage with lower internal capacitance than conventional valves.. This all results in a clean and detailed sound, therefore extracting so much more from your vinyl! Every NV-08 has an internal linear power supply, employing two R core transformers, with the complete power supply heavily shielded to  minimise any potential PSU hum and stray magnetic affects. The NV-08 offers both MM and MC inputs with Mono facility for both inputs. We use Silver RCA sockets and Silver/Teflon wire for an optimal signal path. The Volume control features a high quality Alps potentiometer, for using the Phono stage directly into power amplifiers.

On the rear panel we have added a “high and low” sensitivity switch, to best suit the output of the cartridges being used.

We now offer options for a 24 position stepped potentiometer and a Potentiometer by-pass facility. The NV-08 is available with black or silver front panels, and for an extra charge a lacquered hard wood front panel.
