Product Description

Nova Fidelity HA500H is a high performance hybrid Headphone Amplifier and DAC with Pre-Amplifier and Asynchronous USB DAC functionality to suit audiophiles.

The design incorporates Vaccum Tubes and Solid State Electronics; warm sound is delivered by Vaccum Tube while transparent and dynamic sound is created by the Solid State electronics making the HA500H sure to fascinate music-lovers and audiophiles.

HA500H Overview

Featuring two ECC82 vacuum tubes and solid state OP Amps, it will work as preamp stage for the headphone section or out stage for the pre-out section. Solid state transistors are integrated for headphone section so you can choose either Tube and OP Amp to suit the character of music or your feelings and mood. HA500H offers high or low impedance selector to better match your headphones.

Dual ESS Sabre³² DACs

HA500H is equipped with twin Sabre³² ES9018K2M DAC (one per channel), supplementary multicore microcontroller for premium USB Audio DAC, fully isolated A/D circuit design with custom SMPS and Toroidal Transformer as well as high quality aluminum structure made precisely by CNC machine with glass-sanding finish. The two Sabre DAC chips are built in for right and left channels individually. This top performing 32Bit audio DAC offers unprecedented Dynamic Range of up to 127dB and Total Harmonic Distortion plus Noise of -120dB. The isolated circuit-design far increases Dynamic Range to guarantee much better sound quality.

Two ECC82 Vacuum Tubes

Based on patented technologies to fuse solid state electronics with vacuum tube, HA500H was made to give audiophiles and music lovers mellow and enthralling sound with added warmth and depth. A pair of ECC82 Vacuum Tubes are integrated for preamp stage of headphone section and for out stage of pre-out section. It provides a breathtaking sound.

Balanced Circuit Design

The circuit-designed uses fully balanced technologies for internal analogue audio signal path. The single-ended analog input is converted to balanced at input buffer before entering ADC. The balanced analog input goes in as it is. For all digital audio, signal flows in balanced all the way from the DAC through to the output connectors.

Unbalanced outputs originate from the balanced signal as well. This design reduces common-mode noise and boosts siginal quality. The balanced headphone output delivers double the voltage and quadruple the power of the unbalanced output supporting power-hungry headphones. It also delivers greater channel seperation by removing the common ground return path.

Isolated Power and Toroidal Transformer

To lower idle noises and electrical interference, the power source for digital and analogue section is isolated. In place of cheap laminated steel core transformers, HA500H employs customized premium grade toroidal power transformer ensuring superior power efficiency and reducing exterior magnetic fields.

Perfect Asynchronous USB DAC

For those who use PC, X50D or X50Pro as a source, HA500H is a perfect Hybrid Asynchronous USB DAC delivering top-quality sound via the high precision clock precisely driving audio signals. Dual ESS Sabre³² Reference DAC chips inside to convert digital signal to analogue. The HA500H USB DAC Input supports MQA (Master Quality Authenticated), Native DSD64/128/256 and PCM signal up to 32Bit/384Khz to deliver magnificent sound as close to the master recording at studio as possible.

Wireless aptX Bluetooth

HA500H offers Bluetooth receiver so you can play music files in your mobile devices wirelessly. It supports A2DP and AVRCP profiles and SBC, aptX, AAC and MP3

12V Trigger Input and Output

When used as a pre-amplifer, the 12V trigger output can power on the linked power amplifer automatically when HA500H is booted. If you connect it to the trigger output of the connected source, HA500H can be switched on automatically when the source is powered.

Selectable Impedance and Adjustable Gain

HA500H lets you select Headphone Output Impedance (High/Low) to set a proper impedance for best sound quality and matching with your headphones' sensitivity. HA500H's volume can be precisely and seamlessly controllable via the bundled remote control.

The headphone amplifier provides individual adjustments for the impedance and sensitivity of the linked headphones and different levels of audio sources. This enables headphones between 16 ohms and 600 ohms to work perfectly with the HA500H for stunning sound quality.

High Connectivity

The HA500H offers versatile connectivity; it offers Analogue (Balanced and Unbalanced), Digital (Coaxial, Toslink, AES/EBU), I²S HDMI and USB Audio inputs so you can connect various sources almost without limitation. HA500H can be connected to the I²S HDMI Ouput of the X50Pro and X50D perfectly to play Native DSD, MQA and up to 384Khz PCM. Balanced or Unbalanced Line and Headphone outputs are also provided.

Convenient Intuitive Operation

The 5 inch TFT LCD screen on the front panel helps operate the unit easily and displaying information on how it is working. Precise VU meters add a classic feel that matches the warm, analog tone of the tubes. The screen is located in the middle with smart two ventilations sections for the vacuum tubes located on the top surface. Five functions keys control the HA500H and it has three types of Input Level display.

Design and Build Quality

HA500H is rigidly and clearly structured, with a simple exterior design incorporating top quality beautiful glass-sanding aluminum crafted minutely by CNC. For the rear and bottom side, 2mm high quality steel is provides stability and sturdiness while reinforcing resistance from external vibrations.

HA500H is an extremely solid desktop headphone amplifier and DAC. Experience flawless audio via a combination of HA500H and Premium Pure Digital Music Server, cocktailAudio X50Pro or X50D.
