L1500

About the L1500

The Allnic L-1500 is a line stage preamplifier that serves as a budget version of the L-4000 model. It features a single gain stage circuit using one tube for amplification, which delivers a purer, more detailed, spacious, and dynamic sound. The preamplifier has a constant low output impedance of 150 ohms across all frequencies, avoiding distortion issues common in cathode follower circuits. It uses in-house built output transformers with 78% nickel content, which contribute to wider bandwidth and faster energy transfer. The L-1500 offers a mellow, classic tube sound with good bass, timing, and dimensionality, making it suitable for bright systems. It supports both single-ended and balanced inputs and outputs, with balanced operation providing improved dynamics, lower noise, and better imaging. The unit measures 430mm x 300mm x 120mm and weighs 9 kg. It includes 5 pairs of line level inputs (2 balanced, 3 unbalanced) and balanced and unbalanced outputs. The frequency response is 20Hz to 20kHz flat, extending to 16Hz to 75kHz at -3dB. The maximum output voltage is 15V (pre out max), and the signal-to-noise ratio is 90dB (line).
