Parasound's HINT 6 integrated amplifier is loaded with features and design perks that make it an excellent centerpiece of a high-performance two-channel audio system. It offers plenty of digital and analog connections for music sources and delivers 160 watts of clean power per channel. And this amp is stable at low impedances, so it's compatible with a wide range of speakers. All that power comes from a large toroidal transformer and the amp's high-bias Class A/AB amplifier design.
John Curl-Designed Power Amplifier Section
The Parasound HINT 6 uses the same powerful John Curl-designed power amplifier as the original acclaimed Halo Integrated Amplifier. This 160-watt-per-channel (240-watts @ 4 ohms) amplifier is based on John Curl's direct coupled Class A/AB circuit topology found in Parasound's renowned separate power amplifiers. These capabilities are further enhanced with a home-theater bypass function, 2.1-channel analog bass management, a dedicated high-current headphone amplifier, and an MM/MC phono stage.
ESS Sabre32 Reference DAC
The Parasound HINT 6 uses a proven ESS Sabre32 Reference DAC to decode a wide range of digital music files via two optical, one coaxial, and a new upgraded USB receiver – now with plug-and-play support for Windows 10 in addition to Mac. The asynchronous USB 2.0 input supports PCM up to 384 kHz/32-bit, native DSD256, and DoP DSD bit streams. The coax and optical inputs accept PCM up to 192 kHz/24-bit.
Among other circuit improvements are an upgraded op-amp in the preamp gain stage, improved L-R channel separation, and increased gain for the MC and MM phono inputs.
Massive Toroidal Power Transformer and Toshiba JFETs
The heart of HINT 6's power supply is a massive 1.1kVA toroid power transformer. It is custom-designed for well-contained radiated hum, high efficiency, and high power. Encapsulating this massive power transformer in an epoxy-filled steel canister assures ultra-quiet performance. The transformer has independent secondary windings to provide more than ample voltage to each channel's power supply under the most strenuous operating conditions. Separate windings for each channel improves stereo imaging by reducing inter-channel crosstalk. HINT 6 uses a total of 40,000uF of Lelon electrolytic filter capacitors to provide a reserve of massive power sufficient to reproduce unrestricted bass. Highly-coveted Toshiba JFETs are deployed in the input stage of the power amplifier section to achieve stunningly low noise and maximize its dynamic range.
