Hot House Four Hundred High Resolution

Designed to be the ultimate amp for high-quality near-field monitoring (like our PRM165s), the two-rackspace, convection-cooled model Four Hundred is the smallest of the new generation of Hot House amps, utilizing a radical new output topology. Each individual output device is completely self-contained and self-protecting, requiring very little support circuitry in the signal path: no caps, no protection circuits, no phase shift. A massive toroidal transformer provides high headroom for realistic musical transients. Specs: 0.005% THD, 105 dB S/N, 125 watts/channel @ 8 ohms, 200 watts/channel @ 4 ohms, $1,699.

Hot House Six Hundred/One Thousand High Resolution

Using the same innovative, new output technology as the model Four Hundred, both three-rackspace convection-cooled models are designed for near- or mid-field applications. The $2,499 Six Hundred is a universal amp comfortable into any impedance load, while the $2,999 One Thousand is built specifically to drive high-power/high-impedance monitors. A galvanically isolated, split-dual toroidal power supply provides high transient headroom and 3-D imaging. Specs: 0.005% THD, 105 S/N (both). Model Six Hundred power: 175 watts/channel @ 8 ohms, 275 watts/cannel @ 4 ohms, 350 watts/channel @ 2 ohms. Model One Thousand power: 325 watts/channel @ 8 ohms, 500 watts/channel @ 4 ohms.
