Preamplifiers — YBA Passion PRE550 MKII

The Passion PRE550 MKII is a preamplifier from YBA, an updated version of the PASSION PRE550A with a wider bandwidth and near-immeasurable distortion. The Passion PRE550 MKII brings YBA's more accomplished current engineering to dedicated line-level signal control.

Key specs that matter

One balanced XLR input and two single-ended inputs are provided, with one balanced and two single-ended outputs. Frequency response spans an exceptionally wide 20Hz to 40,000Hz within plus-or-minus 3dB - wider than the PRE550A's 20kHz limit. Signal-to-noise ratio exceeds an exceptional 110dB unweighted - higher than the PRE550A's 105dB - with total harmonic distortion plus noise under a near-immeasurable 0.001%. At 430 x 412 x 118mm and 12kg, the Passion PRE550 MKII shares the PRE550A's chassis dimensions with a modest weight reduction.

Sound and use context

Expect exceptionally clean, transparent signal handling reflecting the exceptional over-110dB signal-to-noise figure and near-immeasurable 0.001% distortion figure, representing an update over the original PRE550A.

Pairing
