Preamplifiers — Yamaha C-5000

The C-5000 is a two-box-class preamplifier built as the flagship control unit for a high-resolution analogue and digital source chain, with a dedicated phono stage built in. Yamaha's numbered C-series preamplifiers represent the brand's most serious two-channel electronics, built with considerably more attention to measured performance than its mainstream receiver and AV amplifier lines.

Position in line

It sits at the top of Yamaha's current preamplifier range, distinguished from more modest models by fully balanced circuitry throughout and a built-in phono input alongside line-level inputs - the combination of balanced operation from input to output plus an integrated phono stage is a comprehensive feature set rarely found together in a single preamplifier at any price.

Key specs that matter

Rated bandwidth is an unusually wide 10 Hz to 100 kHz, well beyond audible range by design margin, a common practice among flagship electronics intended to keep the passband flat and free of phase anomalies well within the range humans can actually hear. Signal-to-noise is 110 dB with 0.01% distortion, both flagship-level figures that place this preamplifier's measured performance among the more capable in its category. Input impedance is 52 kOhm balanced and 47 kOhm single-ended, an easy load for any source, meaning gain-staging problems with whatever feeds it should be essentially nonexistent. At 19.1 kg it is a substantial, heavy chassis, consistent with a serious power supply and shielding for the fully balanced circuit topology inside.

Sound and use context

Expect a low-noise, highly resolved presentation consistent with the wide bandwidth and high signal-to-noise figures - built to add minimal character of its own between source and power amplifier, a deliberate engineering choice rather than an accidental lack of voicing.

Pairing

Both balanced and single-ended inputs and outputs are provided, so it works equally with fully balanced power amplifiers or single-ended designs without adapters, a flexible arrangement for building a system around components from different manufacturers.

Alternatives

A more modest Yamaha preamplifier without the built-in phono stage suits a system where vinyl is not part of the source chain, at a correspondingly lower price for anyone who would otherwise be paying for phono circuitry they will never use.
