„we remove what stands between you and the music.”
audio expo 2025
We warmly invite all audio enthusiasts to Room 504 at the 2025 Audio Expo, where we’ll be exhibiting alongside Parabox. We’ll be showcasing Parabox’s new loudspeaker, along with the following audio system:
– Sirius Audio 3000W isolation transformer (5000W soft-start module, noise filter, 6 output plugs, OCC cabling)
– Sirius Audio OCC and silver-plated OCC cabling (Power cord, Ethernet cable, USB cable, RCA interconnects)
– Sirius Audio PC (SOtM motherboard, clock and USB modules, Sirius Audio 300W linear power supply, Sirius Audio playback software)
– Dual ES9038Pro DAC with Sirius Audio tuning
About us
Sirius Audio Projekt is a manufacture established for the research, development, and fine-tuning of audio equipment. Our goal is to offer the highest-level audio devices to music enthusiasts. Our product range encompasses components of home audio systems, with special focus on digital sources, amplifiers, D/A converters, power supplies, and the cables that serve them.
New cable product line
We presents a complete cable family that serves every component of an audio system, all sharing high-purity 6N OCC copper conductors, multiple layers of shielding, premium insulation, and carefully selected connectors. Beyond flawless signal transmission, our cables also reduce high-frequency noise within the sound system, achieving their signature resolution and transparent sound.
We will offer cable sets at prices more favorable than the list price. The concept is designed to equip a single electronic component—or even an entire audio system—with all the cables it requires. With these configurations, Sirius Audio cables have a synergic effect on the system.
Ultimately, our goal is to prove that it is possible to produce excellent audio cables at a realistic price. In the audio cable market, there are products offered at higher prices than the devices they connect. The price of the complete Sirius Audio system cabling set is comparable to that of a single high-quality audio component.
Audio Ethernet cable
Digital cables also influence the sound of the system. While the transmitted data remains unchanged (we have measurements to confirm this), our Ethernet cables contribute to filtering high-frequency noise within the system as well. Based on our experience, replacing an Ethernet cable can make an audible difference not only in devices directly connected to the audio system, but even in more distant parts of your home—such as between the modem and Wi-Fi router.
Our Ethernet cable features multiple layers of shielding and is made from solid 6N OCC copper with a thickness of 22AWG. It is equipped with shielded connectors to ensure optimal performance and noise protection.
USB A-B cable
Similar to our Ethernet cable, the components of our shielded USB cable also contribute to achieving cleaner sound quality.
The digital signal is transmitted through the same solid core as the Ethernet cable, while the power line uses a stranded 6N OCC copper conductor specifically designed for DC power lines.
USB C-B cable
Except for the connector, it matches all specifications of our USB A-B cable. On certain devices—such as laptops—significantly better sound quality can be achieved by choosing a USB Type-C connector. This is because USB-C hardware specification is designed for higher data transfer speeds and to power more demanding devices. As a result, using USB-C with lower-end computers or compact streamers can lead to more stable operation, reduced power noise, and lower jitter.
RCA interconnect
In analog signal transmission, every detail matters—any part of the audible frequency range can fall victim to distortion or attenuation. In our RCA interconnect, conductors are also made of high-quality 6N OCC copper with a specialized strand structure, featuring rhodium-plated connectors and multiple layers of shielding.
XLR interconnect
Unlike the standard configuration commonly used in audio technology (two wires plus shielding connected to the GND terminal), our XLR cable is built with three separate wires and additional shielding. In all specifications, it matches our RCA interconnect cable.
Speaker cable
Our speaker cable is designed to deliver full bandwidth and meet the demands of high-power signal transmission. It is made from 4mm² diameter 6N OCC copper conductors and features shielding as well as solder-free connectors for optimal performance and reliability.
Power Cord
In designing our power cable, we prioritized high power delivery and effective noise filtering. All three conductors are made from 6N OCC copper, feature multiple layers of shielding, and are equipped with solder-free connectors.
Our Philosophy
In addition to manufacturing our own audio products, audio research plays a key role in our company’s operations.
From an auditory perspective, we’re talking about qualities that aren’t captured by a device’s general specifications. The “magic” goes beyond these specs, manifesting in characteristics that the audiophile community has developed a vocabulary for: resolution, staging, dynamics, tonality, coloring, and more. These attributes are virtually impossible to identify through conventional electronic measurement techniques.
Our experience shows that the auditory qualities of music reproduction are related, but not closely tied to circuit design or the application of basic physical formulas alone. In sound quality research, a point is quickly reached where other factors come into play—factors that can only be identified through hands-on experience, and, most importantly, focused listening.
At Sirius Audio, we address these topics with both scientific rigor and genuine enthusiasm.
