In the world of high-fidelity audio, the quest for smaller yet powerful devices continues to fascinate audiophiles and tech enthusiasts alike. Periodic Audio has stepped into this arena with the launch of its Silicon Micro DAC/AMP, a device that's stirring conversations and raising eyebrows with its diminutive size and impressive capabilities.

Dubbed as the ultimate portable DAC, the Silicon Micro DAC/AMP measures merely 27.7mm in length, 10.1mm in thickness, and 12.4mm in width, making it smaller than many 3.5mm headphone plugs. Despite its size, this device doesn't skimp on power. It offers a robust 150+ mW RMS/channel stereo amp and supports PCM formats up to 32 bit/768 kHz and DSD up to DSD256. This means it can handle nearly any high-resolution music format currently available, promising an uncompromised listening experience.

Users are taking notice of its ability to drive nearly any headphone, from in-ears to over-ears, with some highlighting the 150mW per channel into 32 ohms as a particularly impressive feat for such a compact device. There's a buzz about the power and clarity it delivers, especially considering its size.

However, it's not just the power that's drawing attention. Enthusiasts appreciate the Silicon Micro DAC/AMP's simplicity and ease of use — plug in and play without the hassle of switches, knobs, and LEDs. Its design, featuring a black anodized aluminum extrusion and caps molded from Eastman Tritan™, speaks to its durability and the brand's commitment to quality.

While many are excited about this leap in portable audio technology, some discussions turn technical, diving into the DAC's performance characteristics. For instance, there's talk about its amp stage and how it compares to other options in the market. Some users have pointed out specific behaviors under certain conditions, sparking a deeper analysis among the audiophile community.

In essence, the Periodic Audio Silicon Micro DAC/AMP is more than just a piece of tech; it's a conversation starter, a statement in the continuous evolution of portable audio. It represents a blend of miniaturization and power, appealing to those who want no compromise in their audio experience, regardless of where they are. As this device continues to make waves, it's clear that the balance of size and performance will remain a pivotal point in the audio world.

The audio world is abuzz with the latest development from Etude – the Etude 5 speakers, a marvel in sound engineering. Built on the unique philosophy of replicating live musical events, these speakers utilize advanced Balanced Mode Radiator (BMR) technology. This approach, exclusive to Etude and Curvi, ensures the wide-band delivery of fundamental musical frequencies without traditional filtering methods.

Key to their design is the BMR drive units, which operate as conventional pistonic units at lower frequencies and transition to radial bending wave units for higher tones. The Etude 5 speakers achieve an impressive frequency range, from 20 Hz to beyond 20 kHz, setting a new standard in even-handed audio delivery.

Originating from a 2010 prototype, the Etude 5's development journey is a testament to innovation. Incorporating high-quality passive components and strategically placed bass units and tweeters, these speakers are designed for optimal audio coherence and minimal crossover effects. The Etude High Sensitivity Bipole (EHSB), the latest addition, blends horn-like sensitivity with BMR speed and coherence, offering an unprecedented audio experience.

With their groundbreaking design and engineering, the Etude 5 speakers are redefining audio mastery, promising an unparalleled listening experience that's as close as it gets to a live musical event.
