Pass Labs XP-22 Line Level Preamp pair featuring even larger heatsinks andThe new design uses double shielded low noise toroidal transformers in external supply connected via aviation grade circular connectors using silver over oxygen free copper. The power supply is dual mono with two transformers with lower radiated and mechanical noise. Noise is the most prominent part of THD+N at low levels, so by lowering noise we get better resolution and dynamics. The gain circuitry continues to use our favorite transistors from
