There's something new for audio enthusiasts to get excited about. Hidisz has just rolled out its latest offering, the ST2 Pro Digital IEMs, a noteworthy addition to the world of in-ear monitors. These aren't your average earbuds; they're a leap forward, especially for those who've embraced USB-C devices, like the upcoming iPhone 15.

#### High-Quality Sound in a Tiny Package

What's intriguing about the ST2 Pro is its heart – the ESS ES9281C PRO DAC. This little piece of technology is a game-changer. It's capable of handling a variety of high-resolution audio formats, something you'd typically expect from larger, more cumbersome audio devices. The promise here is clear: these earbuds are set to deliver a level of sound quality that could rival what you'd get from more traditional, high-end audio setups, but in a much smaller package.

#### Designed for Real Life

The design of the ST2 Pro seems to be a thoughtful balance between practicality and quality. With 10mm drivers, these earbuds aim to cover a wide range of sounds, from deep bass to high treble. They're also light and come with a flexible, durable cable, which suggests they're built for real-life use – whether that's commuting, casual listening, or even a bit of gaming.

#### A Nod to the Past

Acknowledging those who still hold onto their 3.5mm jack headphones, Hidisz has also introduced the SD2 mini-DAC. This little gadget connects to USB-C devices and offers an output for traditional headphone jacks, bridging the gap between the new and the old.

#### Market Implications and What's Next

The ST2 Pro enters the market at an interesting time. As more devices ditch the traditional headphone jack for USB-C, there's a growing space for innovative audio solutions. Hidisz seems to be tapping into this trend, although we're still in the dark about the price and when these will hit the shelves. But one thing is clear: they're stirring up some buzz among those who care about sound.

#### Final Thoughts

The Hidisz ST2 Pro Digital IEMs seem to be more than just another pair of earbuds. They represent a shift in how we think about portable audio – blending high-fidelity sound with the convenience of modern connectivity. It's an exciting time for audiophiles and everyday listeners alike. The future of portable audio isn't just about going wireless; it's about packing exceptional sound into every possible format, and the ST2 Pro seems to be leading the charge.

In the nuanced world of vinyl playback, phono preamplifiers play a pivotal role. These devices, often simply referred to as phono preamps, are tasked with amplifying the faint signal from a turntable to a level that's usable for a standard amplifier or audio receiver. A question that often arises among audiophiles and vinyl enthusiasts is about the power management of these preamps: Why do many lack a power button, and is it reasonable to turn them on and off?

### The Case for Omission of Power Buttons

Phono preamps typically forgo the inclusion of a power switch for several reasons:

1.  **Continuous Operation**: A common belief in audiophile circles is that audio equipment performs best when it reaches and maintains a stable operating temperature, a state known as thermal equilibrium. This concept suggests that a preamp, constantly powered on, is always primed for optimal performance.
    
2.  **Simplicity in Design**: In high-end audio, the purity of the signal path is paramount. Each additional component in the circuit, including a power switch, is seen as a potential point of signal degradation. By eliminating the switch, the signal path remains as direct and unadulterated as possible.
    
3.  **Automatic Integration**: Some phono preamps are designed to power up automatically upon detecting a signal from the turntable or to be controlled by another component in the audio setup. This seamless integration renders a separate power switch unnecessary.
    

### Power Consumption: A Key Consideration

A notable aspect of phono preamps is their low power consumption. Most models use only a few watts, making them some of the least power-hungry components in an audio setup. This minimal usage often raises the question: is it even worth turning them off?

### The Debate: To Power Off or Not

The decision to power down a phono preamp is influenced by several factors:

-   **Longevity and Performance**: Consistent power to the preamp is argued to prolong its life and maintain sound quality. However, the impact of frequent power cycling on modern electronics is often minimal.
    
-   **Electrical Interference**: In some cases, powering on a phono preamp can cause electrical disturbances, as evidenced by noise or other issues in connected equipment. This might advocate for turning off the preamp when not in use.
    
-   **Energy Conservation**: While the energy savings from powering off a low-consumption device like a phono preamp are modest, every bit counts for those keen on minimizing their electrical footprint.
    

### A Personal Choice

In conclusion, the decision to leave a phono preamp powered on or to turn it off hinges on personal preferences, usage patterns, and specific equipment characteristics. With their low power consumption, the impact on your electricity bill or the environment is minimal, but for those prioritizing energy efficiency or concerned about the long-term health of their audio equipment, powering off is a viable option. As with many aspects of high-fidelity audio, the choice often comes down to a blend of practical considerations and personal philosophy.

In the realm of audio technology, a significant development is set to be unveiled at CES 2024. AURO-3D, a pioneer in audio solutions, is introducing the AURO-CX, touted as the first and only truly scalable next-generation audio codec. This new technology is designed to revolutionize the way audio is streamed and broadcasted, with a keen focus on scalability in quality, channel count, sample rates, and objects within a single bitstream.

AURO-CX stands out for its ability to support multiple resolutions within one bitstream, accommodating 48, 96, and 192kHz sample rates. This flexibility allows content distributors to cater to a diverse audience range, from audiophiles seeking high-resolution immersive audio to a broader consumer base with different bitrate requirements.

The codec also showcases a unique approach to immersive audio, embedding objects in 13.1 immersive audio for a more three-dimensional and higher-quality height channel experience. This method is a departure from traditional techniques, ensuring that the audio quality is not compromised, particularly in the height channels of an immersive setup.

Moreover, AURO-CX encompasses a range of broadcast features like dialogue enhancement and localized audio for multiple languages, making it a versatile choice for a variety of applications. The codec's inherent scalability is a key advantage, offering efficiencies in storage space and reducing the need for multiple encoding passes – a benefit for content creators, distributors, and streaming services.

As AURO-3D prepares to showcase this groundbreaking technology at CES 2024, the anticipation within the audio industry is palpable. The AURO-CX codec is poised to set a new benchmark in audio streaming and broadcasting, offering unparalleled flexibility and quality in audio delivery.
