The LS 100 is a comprehensive preamplifier from ModWright Instruments, built with flexible one-plus-four input connectivity and a versatile three-position gain structure. The LS 100 brings ModWright's considered engineering to dedicated line-level and phono signal control.

Key specs that matter

One balanced XLR input and four single-ended inputs are provided, with one balanced and two single-ended outputs. Gain is versatile at 11dBu (line), 46dBu (phono MM), or 63dBu (phono MC) - a comprehensive range covering line-level and both phono cartridge types. Input impedance is 38,000 ohms on both connections. Output impedance is 300 ohms on both connections. Frequency response spans a wide 20Hz to 100,000Hz within plus-or-minus 3dB. At 450.8 x 444.5 x 165.1mm and 11.34kg, the LS 100 represents a substantial preamplifier commitment reflecting ModWright's considered American engineering standards.

Sound and use context

Expect a clean, versatile signal-handling performance reflecting the comprehensive three-position gain structure, accommodating line-level, MM, and MC phono sources all within one chassis.

Pairing

The comprehensive built-in phono stage covers both moving-magnet and moving-coil cartridges directly without needing a separate outboard phono unit.

Alternatives

Other manufacturers' comparable preamplifiers with built-in phono stages offer alternatives for buyers wanting to compare features at a similar price point.
