Descriere
DAC 2x ES9068AS Amplificateur Casque Discret 5W Bluetooth LDAC aptX HD 32bit 768kHz DSD512 MQA16x Noir
With its S9c Pro, Aune presents a versatile, high-performance HiFi device in an elegantly designed case. The S9c Pro is a DAC and headphone amplifier that can also be used as a volume controller with active speakers. Among the S9c Pro's 1080 components, Aune has integrated high-end audiophile components such as two ES9068AS DAC chips and a USB XMOS interface, enabling it to decode up to PCM 32bit 768kHz, DSD512 and MQA 16x. An ultra-low jitter PLL clock synchronization system and a 50W toroidal transformer coupled to 23900μF capacitors are also present. Its amplification stage is also highly sophisticated, thanks to the integration of 16 dual JFET transistors (2 per output channel). But the special feature of this DAC/headphone amplifier lies mainly in the way it processes the signal. It converts the analog input signal into an I2S signal, enabling it to separate the clock signal from the data, and thus supply the same stream to the XMOS interface and the DAC.
Dual ES9068AS DAC chip
The ES9068AS DAC chip from ESS has been specially designed for professional audio equipment and audiophile HiFi devices. High-performance, it operates in 32bit stereo and is based on ESS Hyperstream technology. It enables the S9c Pro to support sampling rates up to PCM 32bit 768kHz, DSD512 and MQA 16x, while ensuring highly accurate restitution.
PLL clock synchronization system with ultra-low jitter and I2S signal
The use of ultra-low jitter PLL (phase-locked loop) technology enables the S9c Pro to isolate the clock source signal from the analog input signal, and transmit it simultaneously to the USB XMOS interface and the DAC section. It's this sharing of the clock signal source that makes high-fidelity rendering possible. The clock synchronization system also converts coaxial / AES / optical signals into I2S signals, greatly enhancing the quality of the final audio rendering and drastically limiting interference.
A high-performance amplifier stage
The amplifier stage uses an entirely discrete circuit and features two JFET transistors per output channel (16 transistors in all), enabling it to deliver up to 5W of power. A substantial energy reserve enabling the S9c to accompany the vast majority of headphones on the market.
Balanced & Single-ended
With its 3 headphone outputs and 5W output power, Aune's S9c Pro lets you enjoy all types of headphones. It features two balanced 4.4mm jack and 4-pin XLR outputs, plus a single-ended 6.35mm jack.
Bluetooth function
The S9c's Bluetooth reception means you can easily enjoy a wide range of audio sources, such as your smartphone or tablet. Bluetooth functionality also benefits from the S9c Pro's built-in clock synchronization and I2S conversion technologies, and supports the high-resolution LDAC, aptX and aptX HD codecs.
Two listening modes available
Aune offers the option of using the S9c Pro in Normal Mode for a clear, natural sound, or in Pure Mode, which enhances the DAC's performance, favoring a wider soundstage, greater density and therefore a richer, more detailed sound.
External clock compatibility
On the rear panel of the S9c Pro you'll find a 10Mhz BNC input for an external clock. This makes it compatible with Aune S1c, Aune SC1 and Aune XC1 clocks, for example.

Explicatii in ceea ce priveste rodajul echipamentelor, cat si al cablurilor, asezarea optima a echipamentelor in camera de auditie, importanta acusticii camerei si nu in ultimul rand sistemul de alimentare a intregului echipament:
PENTRU BOXE:
- Pentru performante optime este necesara pozitionarea boxelor la o distanta de minim 30-40cm de peretele din spate pentru boxele cu bass-reflex in spate, pentru cele cu bass-reflex in fata, recomandam pozitionarea la o distanta de 10-20cm fata de peretele din spate, dar totodata la o distanta de cel putin 50cm fata de peretii laterali. Tineti cont de faptul ca orice piesa de mobilier din incapere, joaca rol de absorbtie fonica, dar si de difuzie fonica daca acestea din urma sunt din materiale ceramica sau oglinzi, geamuri sau alt material reflectorizant. In acest sens, gasiti pe blogul nostru, multiple articole care va pot ajuta
- Boxele vor ajunge sa functioneze in parametrii recomandati de producator, dupa minim 50 de ore (ideal 100 ore) de functionare la volum mediu. In aceasta perioada de timp, de “rodaj a boxelor”, sunetul va fi la inceput mai artificial, bass-ul nu va fi inca controlat, inaltele rigide iar vocile usor retinute, pe masura ce boxele vor functiona, veti remarca cum bas-ul devine mai controlat, mai prezent si mai voluminos, vocile si sunetele medii devin naturale si mai echilibrate, iar inaltele devin rafinate si detaliate. Exista boxe care necesita un „rodaj” mai amplu de minim 300 de ore mai ales in cazul celor care au difuzoare de kevlar, carbon sau alte materiale de acest tip. Boxele care se „rodeaza” cel mai repede sunt cele care au difuzoare de celuloza.

PENTRU AMPLIFICATOARE, DAC-URI, PREAMPLIFICATOARE, RECEIVER STEREO & HOME CINEMA, SURSE DIGITALE AUDIO-VIDEO:
- Pentru performante optime este necesar „rodarea” echipamentului, In functie de complexitatea componentelor din aparatul dumneavoastra acesta poate dura intre 30-200 ore.
- Rodajul se face la volum minim, fiind astfel suficient faptul ca acesta este alimentat corect conform manualului de utilizare la 220-230 Volti si trece semnal audio sau video dupa caz prin el.
- Echipamentul supus „rodajului” va ajunge sa functioneze in parametrii recomandati de producator, dupa perioada mai sus mentionata. In aceasta perioada de timp, de “rodaj”, sunetul va fi la inceput ceva mai artificial, bass-ul nu va fi inca controlat, inaltele rigide iar vocile usor retinute, pe masura ce echipamentul va functiona, veti remarca cum bas-ul devine mai controlat, mai prezent si mai voluminos, vocile si sunetele medii devin naturale si mai echilibrate, iar inaltele devin rafinate si detaliate.
- In ceea ce priveste echipamentul video precum videoproiector, TV, media player, blueray player, necesita un "rodaj" de cel putin 50 de ore. Lipsa acestuia nu va poate oferi maxim de performanta. "Rodajul" se efectueaza prin simpla utilizare a acestuia, intr-un mod conform specificatiilor mentionate de producator.
PENTRU CABLURI:
- Pentru performante optime este necesara „rodarea” cablurilor, In functie de complexitatea conductorului folosit, cat si geometriei acestuia, „rodajul” poate dura intre 30-100 ore.
- Rodajul se face la volum minim, fiind astfel suficient faptul ca va trece semnal audio sau video dupa caz prin el.
- Cablul supus „rodajului” va ajunge sa functioneze in parametrii recomandati de producator, dupa perioada mai sus mentionata. In aceasta perioada de timp, de “rodaj”, sunetul va fi la inceput ceva mai artificial, pe masura ce cablul va functiona, veti remarca cum bas-ul devine mai controlat, mai prezent si mai voluminos, vocile si sunetele medii devin naturale si mai echilibrate, iar inaltele devin rafinate si detaliate.

Tratamentul Acustic si Izolarea Fonica
Pentru un sistem echilibrat, trebuie tinut cont pe langa asezarea corecta a boxelor in incapere, al echipamentelor, sistemul de alimentare al acestora, tinand cont de instalatia electrica a locatiei.
