Hand made in Kent, England and sitting inside a thick sandblasted anodised aluminium enclosure, the SPARTAN 5 is small in size, but full of quality components. Customers from the USA will be pleased to know that the SPARTAN 5 is available to order in black with a 110V NEMA PSU for $200. Silver and black units are now available to order in the UK for £150, and the EU for €185 with EU plug power supplies now available to ship as standard.

Whether you're new to vinyl and looking for an easy upgrade over a setup like the one above, a long-time record collector looking to further improve over an integrated phonostage, or simply seeking the best practical performance from a moving magnet setup at this price, the SPARTAN 5's clarity and transparency will help you reach another level of immersion in your music. One type of setup that the SPARTAN 5 can bring the greatest improvements to is an upgrade to the low cost phono preamplifiers hidden inside many modern turntables that offer a line level output, as shown below.Īnnotated comparison video from the Audiophil YouTube channel These features make the SPARTAN 5 an excellent upgrade over many integrated amplifier phonostages, in addition to mass market external phonostages that offer no improvement over integrated ones.

Fully linear, RC smoothed, split power supply for a hash-free listening experience with less than 0.5W idle power consumption.

Second order subsonic filtering, integrated into the input network, using hand-matched capacitors to preclude tolerance issues.

Mono switching uncovering detail by reducing noise and distortion on mono and heavily worn discs.

Low background noise from an input amplifier chosen specifically for real moving magnet cartridge impedance characteristics.

Lower distortion of less than 0.0015% through a tuned active RIAA network, carefully matched to the amplifier stage.

Strong RIAA accuracy of ☐.25dB from hand-selected film capacitors, beating contemporary phonostages that barely make ☐.5dB.

With a very low power consumption that makes power switching and startup circuitry redundant, it is not only high-efficiency in terms of power, but also in features, cost, and most importantly performance.Īvailable in black and silver case styles, the SPARTAN 5 measures 110*46*90mmīy innovatively weaving and integrating extra circuitry around a specially selected low-noise amplifier, powered by circuitry unconventional for the 21st century, the SPARTAN 5 attains the following features, often not seen even in double-stage designs: It is an original design that obtains stronger RIAA accuracy, a second order subsonic filter, a mono switch, and a split linear power supply from a single-stage phono preamplifier.

Priced at just £150/€185/$200 including delivery directly from Classic Audio Ltd., the SPARTAN 5 is intended as an upgrade over integrated and low-cost external phonostages alike.
