Classic Audio Ltd. introduces the Spartan 15 MKII, a refined moving magnet phono stage that builds on the acclaimed Spartan 10, cementing the brand’s reputation for high-end audio excellence. Hand-assembled in Kent, England, this compact unit, encased in a robust, sandblasted aluminum enclosure, promises transparency and immersion at a competitive price, making it a standout for vinyl enthusiasts.
Reimagined circuit with upgraded power supply
The Spartan 15 MKII features a reimagined circuit with an upgraded ±17V linear split power supply, inspired by Classic Audio’s PRO series, delivering enhanced headroom and zero switching noise. Utilizing NJM2068 amplifier ICs across two gain stages, it achieves ultra-low distortion (0.0006% THD) and strict RIAA equalization (±0.1dB), outperforming competitors’ ±0.5dB tolerance for minimal coloration. New 100Hz and 200Hz LF X-Feed settings reduce low-frequency noise while preserving stereo imaging, complemented by a 22Hz subsonic filter with hand-matched capacitors to eliminate surface disturbances.
Features
With a signal-to-noise ratio of 78dB and a 25.5dB overload margin, the Spartan 15 MKII ensures a silent background and dynamic clarity, handling cartridges up to 9.5mV effortlessly. Mono switching enhances playback of worn or mono records, reducing noise for a cleaner sound. The unit’s build quality shines, featuring through-hole technology, 1% tolerance components, and gold-plated RCA connectors for reliability and longevity.
Measuring 172x60x110mm and weighing 650g, its shielded design minimizes interference, allowing close turntable placement. The Spartan 15 MKII delivers a 40.8dB gain, matching digital source levels, and supports a 50kΩ input impedance for broad cartridge compatibility. For moving-magnet setups, it offers unmatched transparency, rivaling pricier alternatives. Classic Audio’s focus on quality over gimmicks makes the Spartan 15 MKII a worthy investment for audiophiles.
