The Pass Labs X-600.5 monoblocks put out 600W into any load. These are dynamic yet delicate high-power amps. Each X600.5 contains a potted 1800W custom transformer, 48 MOSFET transistors, six huge 25,000µF filter capacitors, and six immense aluminum heatsinks. There’s also a gorgeous brushed-aluminum faceplate fitted with a cool-blue meter that indicates the level of current in the output stage, and, on the rear, some serious wing-nut binding posts, balanced XLR and single-ended RCA inputs, and an IEC power-cord input. This design is a two-gain-stage, class-A device is arranged in a balanced configuration.
These monoblocks are conservatively rated as 8/10. Please closely check pictures for their beautiful cosmetic appearance. They are dead quiet in operation.
