KECES EPHONO+ is a high-performance phono preamplifier tailored for vinyl turntable systems. Paired with the external linear power supply Ephono Power+, it significantly enhances the signal amplification and sound reproduction quality of MM, MC, and even optical DS Audio cartridges. It offers balanced (XLR) and unbalanced (RCA) outputs, allowing users to flexibly match different preamps or integrated amplifiers, perfectly integrating into high-end analog systems.

The EPHONO+ features switchable gain settings and impedance matching options. In MM mode, it can switch among 40 dB, 46 dB, and 52 dB, while in MC mode, it offers three gain options of 60 dB, 66 dB, and 72 dB, and the MC impedance can be adjusted to 56 Ω, 100 Ω, or 220 Ω, ensuring precise matching and optimal audio performance for different brands and types of cartridges. The RIAA correction accuracy is controlled within 0.2 dB, ensuring that vinyl playback has a precise and natural frequency response.

In terms of performance data, the EPHONO+ provides a full frequency response of 20 Hz–20 kHz, with total harmonic distortion of < 0.004% in MM mode and < 0.03% in MC mode. It also has an excellent signal-to-noise ratio (MM about 86 dB, MC about 78 dB). With a 4 mm thick all-aluminum chassis and good shielding design, it effectively suppresses EMI/RFI interference, making the analog signal purer and quieter.

Additionally, the external power supply Ephono Power is equipped with a high-quality linear power supply, providing stable output of ±24 V DC (48V) and features over-temperature protection (OTP), ensuring stable operation over extended periods. In practical listening, the EPHONO+ demonstrates clear detail, stable soundstage, and rich dynamics, making it an essential phono preamplifier for enthusiasts pursuing high resolution and the charm of analog music.
