At this year's Munich Audio Show, Feliks Audio is captivating the audio community with its innovative tube amplification technology. Lukasz, a representative from Feliks Audio, shared insights into their latest offerings, which include the Envy 25th Anniversary headphone amplifier and a prototype of their first electrostatic amplifier.

**Envy 25th Anniversary Amplifier**

The Envy 25th Anniversary edition marks a significant milestone for Feliks Audio, celebrating 25 years of excellence in audio engineering. This limited-edition amplifier, with only 25 units available worldwide, has been designed to push the boundaries of what was previously thought possible in tube headphone amplifiers. Key upgrades include:

-   Custom-made amorphous core output transformers.
-   A specially designed power transformer.
-   Elrog 300B Feliks-branded power tubes.
-   Additional enhancements aimed at improving synergy and performance. The amplifier also features a stunning black piano finish, enhancing its visual appeal as much as its auditory prowess.

**Mystery Electrostatic Amplifier Prototype**

Feliks Audio also teased a "mystery" reveal—an advanced prototype of their first electrostatic amplifier, which has been in development for over three years. This new amplifier uses the 300B power tube, known for its exceptional quality, and is compatible with both old and new electrostatic headphones. Despite the prototype lacking a final chassis, Feliks Audio promises that the finished product will align with the high aesthetic standards of their current lineup.

**Sound Signature and Customer Feedback**

The new electrostatic amplifier aims to deliver robust bass reproduction—a notable challenge in electrostatic setups—while maintaining the high-resolution and detailed highs that Feliks Audio products are known for. The overall sound signature is described as neutral, consistent with the brand’s philosophy, providing an enveloping, light yet powerful audio experience. This setup is particularly optimized for headphones like the Stax SR-X9000, promising an immersive listening experience.

**Looking Ahead**

Feliks Audio is optimistic about making the electrostatic amplifier available by the end of the year, contingent on the progress of the final design stages. Additionally, the brand plans to focus on enhancing production schedules and reducing wait times for various models, particularly the Envy variants, which continue to be highly popular among audiophiles. Feliks Audio remains committed to innovation and eagerly anticipates community feedback to guide future developments.

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.
