Hybrid Headphone Amplifier cocktailAudio HA500H Silver

Experience not only the beautiful, warm sound of tube amplifiers, but also the transparent, dynamic sound of solid-state electronics.

Natural and superb sound reproduction HA500H will captivate music lovers and audiophiles Pre-amplifier and asynchronous USB DAC for audiophiles.

The HA500H is a premium hybrid headphone amplifier, DAC, preamplifier and asynchronous USB DAC for audiophiles. It features two ECC82 vacuum tubes and a transistor op amp that work as a preamplifier for the headphone section and as an output stage for the pre-out section, while solid state transistors are built into the output stage of the power amplifier for the headphone section. So you can choose between tube sound and transistor sound depending on the nature of the music, your mood and preferences.

All music has its own character. Some music needs to be played clearly and dynamically, while others sound better when played warmly and smoothly. The HA500H is the best device that will allow you to choose different sound signatures for music playback depending on your feelings and the character of the piece.

The HA500H features an impedance selector (High/Low) that allows you to choose between two impedance levels to suit your headphones.

Featuring dual Sabre³² ES9018K2M DACs (one DAC per channel), an additional multi-channel microcontroller for a high-performance USB audio DAC, fully isolated circuitry for the analog and digital sections with dedicated power supplies and a toroidal transformer, and a high-quality aluminum chassis precision-machined with CNC and glass-sandblasted finish, the HA500H is set to become the audiophile's reference hybrid headphone amplifier, DAC, preamplifier, and asynchronous USB DAC.

Two ESS Sabre³² ES9018K2M DACs for Right and Left Channels Two Sabre³² ES9018K2M DACs are built in separately for the right and left channels. This is one of the best solutions for 32-bit audio DACs with an unrivaled dynamic range (DNR) of up to 127 dB and a total harmonic distortion + noise (THD+N) of -120 dB. Since the HA500H uses two DACs for each channel, the dynamic range and sound quality are significantly increased.

Dual ECC82 Vacuum Tubes HA500H is designed with exclusive technologies that combine solid-state electronics and vacuum tubes, allowing audiophiles to enjoy a smooth and captivating sound that adds warmth and depth. A pair of ECC82 vacuum tubes are installed in the headphone preamplifier stage and preamplifier output, providing an exciting sound that will attract audiophiles.

Balanced Circuit The HA500H is designed using fully balanced technology for internal analog audio signal transmission. Unbalanced analog input is converted to balanced in the input buffer, then fed to the ADC. Balanced analog input is fed directly to the ADC. For all digital inputs, the signal is transmitted in balanced mode from the DAC to the output connectors. Balanced circuitry helps reduce noise and improve signal quality. The balanced headphone output provides twice the voltage and four times the power of the unbalanced output, allowing the HA500H to drive high-power headphones. It also improves channel separation by eliminating the common ground return path.

Isolated Power Supply and Toroidal Transformer To minimize noise and electrical interference, the power supply for the digital and analog sections is isolated. Instead of economical laminated steel transformers, the HA500H uses a high-quality toroidal transformer, ensuring high efficiency and minimizing external magnetic fields.

The Ultimate Asynchronous USB DAC and Hi-Res Audio The HA500H is the ultimate hybrid asynchronous USB DAC, delivering stunning sound with a high-precision internal clock and dual ESS Sabre³² Reference DACs for digital-to-analog conversion. The DAC's USB input supports MQA, Native DSD64/128/256, and PCM up to 32-bit/384kHz.

Wireless playback via Bluetooth with aptX support The HA500H is equipped with a Bluetooth receiver, which allows you to play music from mobile devices through the device. A2DP and AVRCP profiles are supported, as well as SBC, aptX, AAC and MP3 codecs.

12V Trigger Input and Output The HA500H offers a 12V trigger input and output to automatically turn on the system when the main unit is turned on, which is especially convenient when used as a preamplifier.

Impedance Selection and Headphone Gain Control The HA500H allows you to select the output impedance (high/low) for optimal sound and to best match the sensitivity of your headphones. The device supports headphones with impedances from 16 to 600 ohms.

High Compatibility The HA500H offers high compatibility with a variety of sources thanks to analogue inputs (balanced and unbalanced), digital inputs (coaxial, Toslink, AES/EBU), I²S input (HDMI) and USB audio input.

Remote control The device is equipped with a convenient remote control for adjusting the volume, changing inputs and settings.

Convenient operation with 5-inch screen The 5-inch TFT LCD screen on the front panel allows you to easily operate the device and display information about its operation.

Design and Build Quality The HA500H has a robust construction with a glass-blasted aluminum body and weighs 6.9 kg.

High-quality sound and Hi-Res Audio The HA500H delivers warm, tube-like sound and transparent, dynamic playback, supporting DSD64/128/256, MQA and PCM up to 384kHz for high-quality sound that is as close to the master recording as possible.
