The Audio Detail NV-08 Nuvistor phono stage uses 4 x Nuvistor mini-valves, with a further 4 triode valves, aimed at the user who loves the valve phono stage sound, but wishes for something slightly more special. Offering a low noise threshold with a fast and lively sound.
Built by hand in the UK, the NV-08 input stage is all point to point wiring with the components mounted on a plated copper substrate; plus a traditional Point to Point 4 triode output stage. The output stage uses 6N6 double triodes, with alternative types such as the 6N1 or 6922, ECC88 variants compatible, if you wish to experiment. 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 detail from your vinyl.
Every NV-08 has an internal linear power supply, employing two R core transformers, with the complete power supply is heavily shielded to minimise any potential PSU hum and stray magnetic affects. The NV-08 offers both MM and MC inputs and a Mono facility for both inputs. Silver RCA sockets and Silver/Teflon wire are used for an optimal signal path. The Volume control features a high quality Alps potentiometer for using the Phono stage directly into power amplifiers, if preferred to using an integrated amplifier or pre-amplifier.
On the rear panel there is a “high and low” sensitivity switch, to best suit the output of the cartridges being used (Moving magnet or Moving Coil).
This amplifier is manufactured to order which usually takes 14 days from payment.
A 24 position stepped potentiometer and/or a Potentiometer by-pass facility can be added at the time of ordering, please enquire about additional cost.
The NV-08 is available with black or silver front panels, and for an extra charge a lacquered hard wood front panel.

Our thoughts:
This is a specialist product aimed at the higher end market for sure. It has musicality in spades, a dynamic and detailled presentation. The ability to 'tube roll' gives the enthuiast a real chance to 'voice' this product to your very own requirements. That's not to say that it needs any improvement, the voicing as a standard offers a very natural soundscape to our ears, with good 3D spacial positioning of instruments. We think it works really well with good quality solid state power amplification, as well as with a valve pre-power combination.
