HP-1: Ultra-High End Headphone Amp

The Neurochrome HP-1 is an ultra-high end headphone amplifier capable of producing up to 3 W into a 20 Ω load at vanishingly low distortion. The HP-1 will drive even the most challenging headphones with the utmost fidelity and natural sonic profile. It is designed to be as close to a straight wire with gain as technically possible. In addition to providing the ultimate technical performance, the HP-1 also provides peace of mind as it contains advanced protection circuitry which will protect your headphones in case of various fault conditions.

Key Features

• Fully optimized 4-layer circuit board.
• Total harmonic distortion: 0.000032 % (200 mW, 300 Ω).
• Total harmonic distortion: 0.000050 % (200 mW, 32 Ω).
• Total integrated output noise: 1.0 µV RMS (A-weighted, 20 Hz – 20 kHz).
• Output power: 3.0 W (32 Ω).
• Output power: 450 mW (300 Ω).
• Gain selectable (+6, +12, +20 dB) by front panel switch to accommodate a wide range of sources, including smartphones, tablets, DACs, and CD players.
• 1/4″ phone and 4-pin XLR output connectors.
• Balanced (XLR) and unbalanced (RCA) inputs.
• ±0.1 % tolerance Susumu RG-series resistors used in critical parts of the circuit to ensure the best possible performance.
• All signal switching is accomplished using relays with gold plated switch contacts.
• ALPS RK097 volume control potentiometer.
• Well filtered switching power supplies followed by onboard low noise linear post-regulators ensuring the highest power supply performance.
• Protection against DC voltage on the amplifier output.
• Integrated mains soft start and 320 Joule surge suppressor.
• ON indicator emitting a subtle and pleasant blue glow.
• International mains voltage compliant (85 – 264 VAC @ 47 – 440 Hz).
• All aluminum chassis made in Canada.

Καλό φαίνεται αλλά πως να γλιτώσεις τελωνείο είναι το θέμα διότι μπαίνοντας στην κατηγορία 2000+ υπάρχουν πιο προσβάσιμες ανταγωνιστικές προτάσεις. Ίσως η αγορά της πλακέτας μόνο να δουλέψει. Και όλα αυτά χωρίς δυνατότητα δοκιμής.
