The HA500H from NOVAFiDELITY* is a premium hybrid headphone amplifier, digital-to-analog converter, preamp and asynchronous USB DAC for audiophiles. 

It’s equipped with two ECC82 vacuum tubes and transistor operational amplifiers, which serve as a preamp for the headphone range and as an output stage for the pre-out range. So, you can choose between tubes and solid state depending on your preference or the type of music you’re listening to. 

Featuring dual ESS ES9018K2M Sabre³² Reference DACs for right and left channels, the HA500H supports up to 32bit/384Khz.

To support as many headphone models as possible, the HA500H comes equipped with a high/low impedance selector switch. This caters for a wide range of source and headphone models and can easily power and support any headphone rated from 16 right up to 600 ohms.

Keeping up with wireless trends, Bluetooth A2DP and AVRCP profiles are supported along with  SBC (Subbabd codec), aptX, AAC and MP3 formats.

The chassis measures 27(W) x 33(D) x 9(H) cm (with feet) and is made of steel with a CNC machined aluminium housing and front panel. The unit weighs 6.9kg.

Dual ESS Sabre³² ES9018K2M DACs

Two Sabre³² ES9018K2M DAC chips are installed separately for the right and left channels. The world's most powerful 32-bit audio DAC solution, the ES9018K2M, offers unprecedented DNR (Dynamic Range) of up to 130 db and THD+N( Total Harmonic Distortion plus Noise) of -113 dB.

Two ECC82 Vacuum Tubes

Using their unique way of combining transistor technology with vacuum tubes, NOVAFiDELITY have designed the HA500H to give audiophiles and music lovers soft and captivating sound while adding warmth and depth to the music.

A pair of ECC82 vacuum tubes are built-in for the headphone preamp stage and for the output stage of the pre-out section, delivering breathtaking audiophile quality sound.

Balanced Circuit Design

The HA500H incorporates a fully balanced circuit for the internal analogue audio signal path. The unbalanced (single-ended) analog input is converted into a balanced signal at the input buffer before being passed to the ADC (analog-to-digital converter). Balanced circuit design helps reduce common mode noise and improves signal quality, and provides twice the voltage and four times the power of single-ended (unbalanced) output enabling the HA500H to drive headphones that require a lot of power.

Isolated Power Source Circuit Design and Toroidal Power Transformer

In order to minimise noise and electrical interference, the voltage supply is isolated. Instead of using low-cost, laminated steel-core transformers, the HA500H uses a special, high-quality toroidal transformer that provides unsurpassed energy efficiency and minimizes external magnetic fields.

Perfect Asynchronous USB DAC and Hi-Res Audio

For audiophiles and music lovers using a PC, X50D, X50Pro, or other digital source source, the HA500H acts as a perfect asynchronous hybrid USB DAC that delivers audiophile quality sound using the built-in high-precision clock to precisely control the audio signal and convert the digital signal into an analog signal with the built-in dual ESS Sabre³² DAC chips.

Offering support for various hi-res audio formats - MQA, DSD(64, 128, 256), DXD(24Bit/352.8KHz), PCM 384kHz / 32bit, HD 24Bit/192KHz WAV/FLAC, and more - the HA500H can deliver the warm and mellow sound created by 2 ECC82 vacuum tubes as well as the transparent and dynamic sound created by 2 high quality OP amps.

Wireless Playback via aptX Bluetooth

The HA500H has a Bluetooth receiver that allows you to play music files wirelessly from your mobile devices through the HA500H. It supports A2DP and AVRCP profiles and SBC (Subbabd codec), aptX, AAC and MP3.

Wide Variety of Connections

Using the analog inputs (balanced and unbalanced), digital inputs (coaxial, Toslink, AES / EBU), I²S input (HDMI) and the USB audio input, you can connect practically all types of source devices to the HA500H.

In particular, the HA500H can be connected to the I²S HDMI output of the X50Pro or X50D to play native DSD, MQA and up to 384 kHz PCM files with great sound quality.

As outputs, the device provides balanced / unbalanced line out outputs and balanced / unbalanced headphone outputs.

Easy to Operate with Remote Control and 5 inch Display

The HA500H’ is easy to control using the included remote control, and the 5 inch TFT LCD screen provides clear information about how the device works. VU meters provide precise metering with a classic feel that matches with the warm, analog tone from the tubes.


Perfect with the NOVAFiDELITY X50D or X50ro

Experience a perfect audio system with the combination of the HA500H and the X50Pro or X50D pure digital music servers.


* A note on the NOVAFiDELITY and Cocktail Audio brands: Korean manufacturer Novatron's X-series is branded as NOVAFiDELITY in the UK and as Cocktail Audio in the rest of the world. Cocktail Audio UK, historically associated with Novatron but now a separate company, has developed a separate product line over the past several years.
