Frequency response: 5 Hz to 100 kHz (+/- 0.2 dB), with a ultra-low noise toroidal power supply that results in exceptional low-level detail and dynamic contrast.4. Inputs: five single-ended RCA and one balanced XLR, as well as dual-stage mono subwoofer outputs and a symmetrical headphone output with its own dedicated power supply.5. Control: front-panel volume control, or remote control using the company's KSS Classic series remote control.6. Protection circuitry: an automatic turn-on feature, as well as thermal, overcurrent, and short-circuit protection for the amplifier's vital components.7. Construction: all critical signal paths are hardwired, with relay-controlled switching of the input and gain selections. The unit uses heavy-duty transformers, highly transconductant JFETs, and super fast Darlington transistors which are optimized to Krell's stringent performance requirements.Overall, the Krell KSA-250 is a high-quality integrated amplifier that balances exceptional power and detail with user-friendly features and versatility. However, as a discontinued model, spare parts and technical support may be limited, and replacement by a modern Krell or other brand's amplifier is recommended.
