Krell KSP-7B
Brand: Krell
The Krell KSP-7B is a high-end audio power amplifier designed by the American audio equipment manufacturer, Krell. It was first introduced in the late 1980s and was a significant update to its predecessor, the KSP-6.The KSP-7B amplifier boasts a power output of 250 watts per channel into 8 ohms and 400 watts into 4 ohms. It uses Krell's patented "Fffête IV" topology, which combines MOSFETs and bipolar transistors to deliver a fast and detailed sound. The amplifier also includes Krell's CAST (Class A/Class Split Technique) circuitry, which allows the amplifier to operate in Class A mode at lower power levels for improved dynamics and clarity.One of the most notable features of the KSP-7B is its impressive build quality. The amplifier is housed in a massive, custom-machined extruded aluminum chassis, with external heatsinks and a sleek, minimalist design. The unit is also equipped with high-quality components, including WIMA polypropylene capacitors, Vishay metal film resistors, and JRC op-amps.In terms of performance, the Krell KSP-7B is widely regarded as one of the best power amplifiers ever produced. It offers a clean, detailed, and dynamic sound, with impressive resolution and separation of individual instruments and voices. However, due to its high price and large size, it is primarily aimed at audiophiles with dedicated listening rooms and significant budgets.In summary, the Krell KSP-7B is a high-end, reference-quality audio power amplifier that combines dynamic power, detail, and speed with superior build quality and advanced circuitry. It is a definitive statement in audio electronics engineering and despite being launched several decades ago, it remains a benchmark for audio equipment today.
