COCKTAIL AUDIO HA500H

The Cocktail Audio HA500H is an excellent headphone hybrid amplifier, DAC, line preamplifier for audiophiles that are more advanced.
And has at the same time of two (2) valves, ECC82 and OPAmp solid state, which function as the pre-amplification stage for the headphone section, and as the output stage for the preamp section-out, and the transistor to solid-state drives are integrated in the power output stage for the headphone section.
Then, you can select the option of listening to the vacuum tube, or through the amplification of the solid state of the OPAmp, depending on the genre of music, their feelings and mood.
Every musical genre has its own intrinsic character: you might want to listen to a song which needs the maximum dynamic and clear reproduction typical of the solid state, while in other circumstances you may prefer listening to music that will make the best if played in a warm and gentle through the output valves. It's up to you!
Depending on your tastes, your needs, your mood, the HA500H will be the more flexible system, which allows you to choose a different imprint of the sound reproduction of your favourite music according to your feelings and to your musical preferences.
The Cocktail Audio HA500H is equipped with a selector of impedance with which you can set between the impedance High or Low, to obtain a matching perfect with your headphones on.
Equipped with a dual-DAC Sabre32 ES9018K2M (one DAC chip per channel configuration to Dual Mono), a microcontroller, multi-core add-on for audio DAC high-performance USB, a power supply circuit fully isolated and distinguished based on a toroidal transformer for the analog section, and a switching mode power supply SMPS for the digital, the HA500H arises as the DAC reference Headphone Amplifier, Pre-Amplifier for all music enthusiasts, which are looking for the best audio performance.
A device of this level is complete with the adoption of a chassis of aluminium of very high quality and beautiful satin finish, constructed with the highest precision through the use of a CNC machine numerical control, and is available in Black or Silver.

DUAL DAC ESS SABRE32 ES9018K2M IN DUAL MONO CONFIGURATION
Two DAC chip Sabre32 ES9018K2M are integrated separately to the left and right channels. Considered as the platform, audio DAC 32bit with the best performance in the world, the ES9018K2M delivers a DNR (Dynamic Range) of up to 127dB and a THD+N (Total Harmonic Distortion plus Noise) of -120dB. Because the CocktailAUDIO HA500H is designed with two DAC chip for each channel separately, its dynamic range will be far superior and the quality of the sound will be much better.

TUBE CIRCUIT WITH 2 VALVES ECC82
Based on our unique technology, developed to match the solid-state electronics with the valves, the HA500H is designed to allow audiophiles and music lovers to experience sound fluid and engaging, adding warmth and depth to the music.
A pair of valves-ECC82 is installed for the preamplifier stage of the headphone section and to the output stage of the pre-out.
This helps provide an exciting sound and of the highest level, capable of capturing the attention and to play with extreme naturalness in the music program.

DOUBLE SEPARATE POWER SUPPLY AND INDEPENDENT
To minimize the background noise and electrical interference, the power source for the digital section and the analog is designed so that it is completely independent.
The digital section is served by a switching power supply SMPS.
While for the analog section, instead of the traditional lamellar transformers, the HA500H employs a toroidal transformer oversized, high quality, realized on a specific proprietary, which ensures efficiency without equal, and which reduces to a minimum external magnetic fields.
These measures result in a better separation of the channels and a drastic reduction of the phenomenon of cross-talking and diaphonies.

DOUBLE CONVERTER THE ESS SABRE ES9018 32BIT/384KHZ
Precision 32bit, plays native formats DSD, MQA, PCM, and DXD

AUDIO HIGH-RESOLUTION 32BIT/384KHZ – DSD256 – MQA
For audiophiles and music lovers who use the source as a PC, a CocktailAUDIO X50D or a CocktailAUDIO X50Pro, the HA500H is the DAC asynchronous USB hybrid the perfect, who delivers a sound of exceptional quality using the internal clock of high precision, to drive with extreme accuracy the audio signal and two-chip DAC Reference ESS Sabre32 Reference, to convert the digital signal into analog.
The input USB DAC HA500H supports natively the signals MQA (Master Quality Authenticated), the signal DSD64/128/256 native signal and PCM up to 32Bit/384Khz.

THE CIRCUIT IS COMPLETELY BALANCED COCKTAIL AUDIO HA500H
The HA500H is based on a circuit designed with technology that is completely balanced for the path of the analog audio signal inside.
The analog input unbalanced (single-ended) is converted to a balanced signal in the input buffer, and then passes into the section of ADC (Analog to Digital Converter).
The analog input balanced instead, it is passed to the ADC as it is.
For all digital audio inputs, the signal flows in the mode, fully balanced from the DAC to the output connectors.
Also, all the outputs single-ended (unbalanced) are derived from the balanced signal.
The circuit is balanced definitely helps to reduce the common mode noise and improves the overall quality of the audio signal, keeping it as close as possible.
The headphone output balanced - delivers twice the voltage and four times the power of the single-ended ( unbalanced), allowing the’HA500H to drive headphones that require plenty of power.
It also provides a better separation of the channels, eliminating the path back to the point of common ground.

HEADPHONE OUTPUT IMPEDANCE ADJUSTABLE FINELY
The CocktailAUDIO HA500H provides you with the function selection of the output impedance of your headphones, so you can set the impedance correctly for optimum sound quality. and to achieve the best match with the sensitivity of your headphones.
You can select one of two options available, namely, High or Low.
The volume of the HA500H can be controlled precisely and without solution of continuity via the convenient remote control supplied.
The headphone amplifier also provides separate adjustments for the impedance and the sensitivity of the connected headphones, as well as setting volume levels for individual audio sources.
These features allow you to perfectly match with HA500H headphones between 16 ohms and 600 ohms obtaining a superb audio quality.

INPUTS AND OUTPUTS ANALOG XLR AND RCA
The DAC CocktailAUDIO HA500H has inputs and outputs unbalanced RCA and balanced XLR.
This is a real line preamplifier, capable of operating in mode, valve or transistor.
Throughout the entire signal path is fully balanced. In the case of the analog input signal, this is processed by a dedicated conversion section ADC (Analog to Digital Converter), which operates also in the configuration, fully balanced.

DIGITAL INPUTS HIGH-RESOLUTION
Rich is the equipment of the Digital Inputs high resolution of the DAC Reference CocktailAUDIO HA500H.
You immediately notice the presence of the bond connecting the digital I2S HDMI, perfect for connecting to the CocktailAUDIO X50D and CocktailAUDIO X50Pro.
The connection to the I2S (HDMI) enables the playback of the encoding to DSD-256 native, file PCM up to 384Khz and MQA (Master Quality Authenticated).
Equally versatile and high quality the USB Audio Class 2.0, which can support all streams PCM up to 32Bit/384Khz, the DSD256 native as well as the encoding MQA native up to 384Khz.
There are, of course, the traditional digital connections, electrical, as the input digital Coaxial RCA 75-Ohm, the input Optical Toslink, and AES/EBU XLR 110 Ohms, all of them capable of receiving digital audio streams to stereo, up to 192Khz.
