The October HP 300 SE is an evolution of the HP 300 MK2, which itself took inspiration from the distinguished Jubilee Preamp. This preamplifier enhances the lineup with its extensive connectivity options and superior sound quality, stemming from advancements in its power supply and the output stage of the line amplifier. A hallmark of the HP 300 SE is its newly developed line stage, which boasts an impressive signal-to-noise ratio.
The HP 300 SE distinguishes itself from its predecessor, the HP 300 MK2, through several significant developments. A major enhancement is its external power supply, which employs cutting-edge technology to ensure refined power delivery. The improved amplifier circuitry offers three stages of gain amplification, complemented by XLR outputs with specialized transformers, all housed in a refined casing. This progression ensures the HP 300 SE bridges the gap to more premium preamplifiers, catering to discerning audiophiles.
Central to its engineering is the external mains transformer, optimized with advanced filter characteristics. The preamplifier features meticulously calibrated, low-noise voltage regulators, which work in tandem with the external transformer to minimize noise and interference, elevating the listening experience. Notably, the balanced output is enhanced with a precision balancing transformer, allowing users to toggle the ground connection to prevent any leakage currents, thus maintaining sound integrity.
The HP 300 SE offers remarkable flexibility with two XLR inputs, three RCA inputs, a monitor output, two RCA outputs, and an XLR output. The monitor output is versatile, capable of connecting to a headphone amplifier, recording devices, or even a PC's A/D input. An optional feature is the phono MC input, which comes with various settings, allowing users to adjust the gain across three levels for optimal speaker efficiency. With notably low output resistance for both XLR and RCA outputs, the HP 300 SE permits long cable runs of up to 10 meters without compromising sound quality.
Incorporating a multi-channel bypass function adds to the HP 300 SE's modern appeal, facilitating integration with home theater systems. This feature can be activated for an RCA or XLR input, reflecting its thoughtful design accommodating contemporary needs. Available in elegant silver or black finishes, the HP 300 SE embodies a blend of classic inspiration and innovative advancement, making it a versatile and high-performance centerpiece for audiophiles.
