Key specs that matter
Balanced XLR connections number three in and two out, and the single-ended RCA side mirrors that count. Input impedance is 20 kohm balanced and 10 kohm single-ended, and output impedance stays under 50 ohms on both output types. Unweighted SNR is better than 105 dB, and THD plus noise stays under 0.001%. The preamplifier measures 432 x 216 x 483 mm and weighs 11.5 kg.
Pairing
Given its sub-50-ohm output and the mix of balanced and single-ended connections, the Inspiration 2 Preamplifier works with a wide range of sources and power amplifiers without unusual matching concerns.
Alternatives
Constellation Audio's Performance 2 Preamplifier is the higher-tier option, built as two enclosures that separate the audio circuits from the power supply.
