Preamplifiers — McIntosh C49

The C49 is a preamplifier from McIntosh, built with a rich set of balanced and single-ended connections. This model represents a serious mid-to-upper tier preamplifier within McIntosh's catalogue, offering the brand's characteristic build quality and connectivity for a system built around separate power amplification.

Key specs that matter

Two balanced and three single-ended inputs are provided, with two balanced and one single-ended output. Gain is 60 dBu. Input sensitivity is 900 mV via XLR and 450 mV via RCA. Output voltage is 16 V via XLR and 8 V via RCA, both healthy figures that should drive most power amplifiers, including passive-adjacent designs, without difficulty. Input impedance is 44,000 ohms balanced and 22,000 ohms single-ended. Rated bandwidth is 15 Hz to 100 kHz. Signal-to-noise is 100 dB with distortion at 0.005%. At 444.5 x 152 x 457.2 mm and 10.4 kg it is a substantial chassis.

Sound and use context

Expect a controlled, low-coloration presentation typical of McIntosh's preamplifier engineering, with healthy output voltage levels ensuring strong drive into most power amplifiers - a house sound generally associated with careful attention to measured performance alongside the brand's characteristic build quality and visual identity.

Pairing

The rich set of balanced and single-ended inputs and outputs covers an extensive multi-source system, and the healthy 16 V balanced output should drive even a demanding power amplifier input without gain concerns.

Alternatives

McIntosh's broader power amplifier range, including the MC303, forms a natural partner for a system built around this preamplifier, worth pairing together for a coherently voiced, brand-consistent signal chain. McIntosh extensive dealer network makes arranging a direct comparison against the brand broader preamplifier range practical, helping clarify whether this specific tier suits a particular system and budget. McIntosh distinctive blue-meter aesthetic, absent from a pure preamplifier like this one, is still worth experiencing directly at a dealer to understand the brand full visual identity across its range. A dealer visit remains the simplest way to compare current pricing across McIntosh preamplifier range. Cable and stand choices matter far less at this price point than getting the basic source pairing right. Overall this remains a capable, well-connected preamplifier choice within McIntosh electronics catalogue.
