About the Theater Standard
The Krell Theater Amplifier Standard is a robust 5-channel multichannel power amplifier from the early 2000s, renowned for its Krell signature sound featuring incredible bass, power, headroom, and speaker control. It features massive 4000VA toroidal transformers (two 2kVA each), 108,000µF capacitance, and a quadruple-Darlington output stage with ten bipolar output devices per channel for high current delivery. Supports bridged operation for adjacent channels (800W into 8 ohms) and Multi Amp Throughput (MAT) mode. Built with all-aluminum chassis in the USA, it requires a dedicated 20-amp circuit. No longer manufactured, it remains sought after by audiophiles for home theater and multi-channel setups.
