THIEAUDIO Monarch MKIII

Introducing IMPACT2

The IMPACT2 (“Impact Squared”) is THIEAUDIO’s latest technological innovation to change the personalized audio industry. IMPACT2 is a new subwoofer solution consisting of two 10mm composite diaphragm drivers arranged in an isobaric design. The addition of another 10mm subwoofer significantly enhances the power and texture of the bass, while our in-house isobaric chamber design keeps the frequency and pressure constant. This means you can enjoy better quality bass without sacrificing tonal integrity.

Monarch, Pushing beyond the Pinnacle

At their times, the original Monarch and the Monarch MKII set new standards for best-in-class performance in the global IEM industry. Not only did it redefine the price-to-performance bracket, but it forever changed how IEM manufacturers engineer and tune IEM’s. Keeping with the times, the Monarch has undergone another revision to revamp its technical and tonal performance.

With updated drivers, tuning strategies, and significantly improved ergonomics, the Monarch MKIII offers the legendary performance of the MKII with enhanced technicalities and comfort.

Enhanced Ultra-Treble Output

The Monarch MKIII has been updated with Sonion’s latest electrostatic (EST) drivers and re-tuned to better exhibit these drivers’ full potentials. Thanks to our new tuning strategy, the ultra-treble frequencies at +15kHz to 20kHz have been increased for a more comprehensive upper frequency extension. Compared to its predecessor, the Monarch MKIII will have a greater sense of staging, atmosphere, and an overall enhancement in perceived resolution thanks to the treble extension.

Balanced Tonal Signature

At the core of the Monarch MKIII is THIEAUDIO’s commitment to tonal excellence. The Monarch MKIII retains a studio-monitor like tonal signature with a focused sub-bass impact for a clean, natural, and detailed sound. Engineered with a true 4-way crossover with 9 separate passive components, the Monarch MKIII stays true to its tonal legacy. Thanks to IMPACT2 , the subbass is punchier, but the mids from 200Hz to 800Hz retain their ruler-flat neutrality. This tonality of the mids mimics the true sound of studio monitors used in recording studios to deliver accurate audio reproduction.

Furthermore, compared to its predecessors, the Monarch MKIII mids have been revamped with a new tuning strategy, which better separates respective driver ranges to maximize output while minimizing the total harmonic distortion. This means the mids on the MKIII will sound higher in resolution while retaining the same monitor-esque tonality. The treble has also been slightly re-tuned to offer more coherency throughout the region, as well as little more clarity and definition. This slight tonal modification better mixes with the renewed ultra-treble response, providing a more crisp sound signature.

Medical Grade Resin Housing

Each Monarch MKIII unit is individually handmade by our dedicated engineers. The housing is constructed from 3D-printed medical-grade resin, which is safe on the skin and durable. Additionally, each faceplate of the Monarch MKIII is individually decorated and coated, presenting a truly bespoke experience.

Upgraded Modular Cable

The Monarch MKIII has been upgraded with Thieaudio’s latest modular cable. The upgraded cable is composed of thicker 22AWG 6N OCC silver-plated and graphene silver-plated composite wires. This upgrade in cable materials provides a little more clarity and refinement compared to the previous generation of Thieaudio’s modular cables. With three separate interchangeable plugs at 3.5mm single, 4.4mm balanced, and 2.5mm balanced terminations, you can easily pair the Monarch MKIII with any device, without changing cables.

Delighted of Devon

These are a very rewarding listen particularly when paired with my mojo 2. - crossfeed deepens the soundstage and I roll the treble back a tad .
The downside is that my speakers now sound poor in comparison and I’m going to have to shell out to find some on a par with these fabulous Monarchs

Clarity

I purchased these to use with the Earmen L amp MK2. I have the Mega5est and I wanted an iem that would be a good upgrade to them. And they are. The bass is tighter more controlled and clearer. The midrange is so clear I can hear the faint exhalation of breath in the vocals on the album 'till we meet again' by Christian Loffler. There is a degree of depth and separation I have not heard before in my music.
My only critique is that they might sound a bit too clinical on a bright sounding Dac/amp. And are not as smooth or as totally immersive as the Mega5est, so I am glad I have both, one for studio monitor listening sessions and the other for sheer pleasure & enjoyment.
They were in-stock when I placed my order with Elise and they were delivered in 24hrs. I have used Elise a lot during the past 2 years due to their competitive prices, fast delivery and are UK based.
