Power-line conditioning and exotic power cords, once considered the lunatic fringe of tweaking, have become normal parts of audiophile life. Over the last several years Shunyata Research, founded by former NSA research scientist Caelin Gabriel, has established itself as a leading innovator in the area. The company's latest efforts include the Hydra Model 8 power-distribution center ($1995), for use with whole systems or front ends; the two-outlet "mini" Hydra Model 2 ($395), intended for use with power amplifiers; and the Anaconda Alpha and Anaconda vX power cords ($1995), the new top models in the PowerSnakes line.
When I arranged to review the Bryston 28B-SST monoblock power amplifier, I wanted to be certain that the 1kW amplifier wouldn't be starved for current. Bryston advised me that Plitron, who manufacture the 28B-SST's toroidal transformer, also make Power Isolation Units (PIUs), under the brand name Torus Power. Torus explained that its PIUs combine surge suppression with massive toroidal transformers to provide AC power conditioning and protection from voltage surges.
