Jude Mansilla:
Meze Audio we'll be showing a prototype of a new premium universal fit IEM called the RAI Penta, ‘RAI’ meaning ‘heaven’ in Romanian and ‘Penta’ referring to its five drivers per se. In each fully CNC sculpted chassis, there are two dual balanced armatures and one electrodynamic driver. I haven't heard it yet but Meze is aiming for what they're calling a reference class balanced sound signature with natural tonality. (…)RAI Penta has some interesting details inside and a gorgeous design.
Make sure not to miss the Empyrean, the RAI Penta and the rest of the product line at Meze Audio’s exhibiting it at CanJam Singapore 2018.

The Penta Hybrid technology enables us to deliver harmonized sound frequencies without overlay of phase issues. For sound from the drivers to reach your eardrums it has to pass from through the housing / nozzle / eartip assembly. The seamless functioning of 5 drivers is enabled by the very specific and precise length of each sound tube which basically determines the air volume in front of each driver in particular.

Our design eliminates imperfections that you can find in regular plastic Tube and Dampener systems, which are commonly used in multi driver assembly.

The comfier the IEM, the better the listening experience, this is a fact. Serious audiophiles will spend hours on end engaged in their music.

We have designed the RAI In Ear Monitors to deliver comfort and prolonged listening sessions allowing for a truly immersive experience for you and your music.

Attention to details to an extreme: round, soft edges designed to embrace the natural curves from one’s ear and to fit perfectly.

Airflow control helps regulate internal chamber pressure trough our finely tuned PES design in front and behind the driver assembly.

The high precision CNC aluminium chassis, skillfully milled from solid aluminium, creates the perfect space for the sound to be precisely channeled to your inner ear directly and without distortion.

The Rai Penta work effortlessly with any device due to its low impedance and high sensitivity but to truly enjoy the potential of its painstakingly tuned driver array, we recommend a high resolution source. The response is super high resolution and is above any certificate or standard.

A balanced sound signature with impeccable micro-detailing provides unrivaled realism all across the wide frequency range, from 4Hz to 45 kHz.

How different is this to what I heard at the Hong Kong High End Audio Expo last year? I remember there were 2 versions then, and Antonio mentioned they were single dynamic driver designs? I'm super excited for this since I was struck by the warmth and power of the darker coloured shell prototype last year.

any impression from canjam singapore
Very balanced, slightly neutral, nice build quality and design (the brass/gold version is nice). fitting is decent, but not isolating.
