About the S/7000e
The Threshold S/7000e is a high-power monoblock STASIS power amplifier from Threshold's "e" series, designed for demanding home theater and high-end audio systems. It is rated at 600 watts into 8 Ω and 1000 watts into 4 Ω, extending the circuit topology used in Threshold's flagship STASIS amplifiers. The S/7000e shares the 19-inch rack-mount faceplate and industrial styling of the S/5000e, and was marketed as part of Threshold's affordable high-end range, suitable for multichannel systems when combined with matching Threshold amplifiers. Marketing literature describes it as a DC-coupled, non-inverting STASIS design with complementary-symmetry output stage and optical bias, in line with other S-series "e" STASIS amplifiers, although detailed input (balanced/single-ended) and connector specs are not explicitly documented for this specific model.
