Roon Ready Writeup: Meze Audio Rai Penta and Advar In-Ear Monitors

In the last few DAC reviews I’ve written for The Roon Store, I’ve been somewhat coy about the headphones I used to demo the devices. And let me tell you, it was hard to keep the reason for that a secret. Now, I can dispense with mystery and reveal our new partnership with Meze Audio. Like most music fans and audio gearheads who have heard Meze Audio’s products, we’re blown away by their design, build quality, and sound.

Meze has taken the audio world by storm since the release of their 99 Classic in 2015. And they’ve continued that streak with each follow-up product they’ve unveiled – dethroning some of the most revered headphones on the market in their quest for perfection. Now that we’ve spent quality time with their headphones, we can attest that their mountain of audio awards is well deserved.

Our passion at Roon is to help you get the most musical sound reproduction possible from your system. Our Meze partnership places us in a unique position to realize that goal; few devices can transport you to an entirely new acoustic space and elevate detailed listening and music appreciation in the way a quality pair of headphones or IEMs can. They’re high-quality audio devices you can take anywhere. The abundance of small portable, affordable DAC/amps means easy high-res audio on the go – everywhere you go.

Musical Mysticism:

Meze’s products have an alluring quality inspired by the heritage of their Romanian birthplace. They create a stunning harmony made of timeless aesthetics and acoustic advancements fueled by a yearning to challenge the barriers accepted by the mainstream audio manufacturing community.

I can’t say that I’ve been overly concerned with headphone cosmetics in the past. If they sound good and are reasonably comfortable, that’s been my benchmark. Meze changed that, their products are artworks that produce sound. Once you’ve seen and heard them, the thought of returning to ugly plastics is truly disheartening.

Advar takes its name from Romanian Mysticism, the Advar was a powerful talisman that blessed those who wore it. Just as the Meze Advar, finished in high-gloss black chrome and textured yellow gold, blesses the listener with a warm, dynamic sound. The precisely tuned 10.2 mm dynamic driver is easily driven by standard mobile devices but shines with a bump in power. Advar’s EQ curve sounds similar to the Meze 99 Classics, with a slight emphasis on the bass, upper midrange, and the mid-treble.

The Rai Penta is Meze’s flagship IEM. The aesthetics, innovation, and build quality of their full-sized headphones are miniaturized in Rai Penta with incredible precision. They’re also the most lightweight, well-fitting, and comfortable IEM I’ve ever worn. The pebbled space-blue anodized finish is etched to display Meze’s lyre logo. Its beauty is matched only by its sound.

Rai Penta features a perfectly tuned, five-driver, hybrid array that delivers a pristine, harmonically balanced, sound signature with remarkable detail across their entire frequency spectrum. Meze’s Pressure Equalization System graces Rai Penta with a soundstage resembling their flagship Empyrean and Elite models – packing incredible value into its jewel-like enclosure. Like Advar, the efficiency of its driver array means it can be powered by ordinary mobile devices. But, when paired with a headphone DAC/amp it delivers lustrous listening.

Kick Out the Jams

For our listening tests, I demoed each track with Advar, followed by Rai Penta, to reveal the unique sonic characteristics exhibited by the different models. They were paired with Chord’s Mojo 2 portable DAC with the EQ and Crossfeed features set to “off”.

Fleetwood Mac – Gold Dust Woman from Rumours

Advar: This is pure 1970s album rock gold-dust at its most sublime. Advar’s subtly enhanced voicing makes it a perfect companion for this track. Each instrument in the mix is afforded ample room to breathe. Mick Fleetwood’s metronome-like rim shots are crisp, and McVie’s bass line is warm, fat, and natural. Buckingham’s layered guitar parts sparkle while Christine’s keyboard adds understated yet perfect color. Stevie Nicks’ spellbinding vocals exhibit an intoxicating depth of emotion and yearning. As the song builds and the mix thickens, the airy sense of space is retained. If I only had five minutes with Advar to make a purchase decision, this track would seal the deal.
Rai Penta: Through Rai Penta, the experience is like sitting in the studio with the band for the final mixdown. Highs are spectacularly vivid and overall resolution is truly breathtaking. The soundstage is more spacious but not exaggerated. The instrumentation benefits from pronounced clarity and depth, the air around Stevie’s vocal is ethereal and vocal harmonies display added texture and nuance. There’s no denying that it’s a reference sound signature, but one that’s pleasing and inviting.

Compay Segundo – Yo Vengo Aquí from Nueva Antología. 20 Aniversario

Advar: Antologia (originally titled Yo Yengo Aquí when released) was recorded a year before Segundo garnered renewed fame as the elder statesman of the Buena Vista Social Club album and documentary. He’s joined here by a Trio from Madrid for a set of Cuban and Spanish folk standards. The soundstage here is gorgeous, and the small, lively recording space adds a rich organic compression to the track. Compay’s fluid guitar lines weave through the mix as his warm voice anchors the Grupo. Spanish lead vocalist Julio Fernández fits hand in glove with Segundo’s baritone and adds tasty maracas texture. Benito Suarez deps nicely on the second guitar as Salvador Repilado’s Contrabasso provides a robust foundation. Few listeners would believe this was a quickly assembled ensemble with just a few hours of rehearsal under their belt before these recordings. Yo Vengo Aquí flows from the Advars like pure honey.
Rai Penta: here Yo Vengo Aquí jumps from the Rai Penta like a dancer and mirrors the presentation of the previous track. Hidden details reveal themselves more effortlessly; the interplay of the instruments exhibits greater nuance and vocals are more distinct. The crispness of the acoustic guitars is enhanced, spotlighting their instrumental dexterity. Surprisingly the maracas feel slightly recessed when heard thru the Rai Penta. Rai Penta’s bass voice is full and natural but the added warmth and richness of Advar’s gentle bump in the lows is missing here.

Gábor Szabó – Mizrab from The Socerer

Advar: Mizrab was recorded before a live audience at Boston’s Jazz Workshop in April 1967. The ringing decay of the hand cymbal in the opening perfectly showcases Advar’s smooth upper register, as the remaining instrumentation highlights its accurate, life-like expressiveness. Szabo’s amplified acoustic unfurls fluid serpentine ribbons of mesmerizing gypsy jazz guitar throughout the piece. Hal Gordon’s hand drums feel like they’re just a few feet away as they establish a pulsing rhythmic exchange with Marty Morell’s kit. Advar places you right at the heart of Mizrab’s hypnotic musical journey.
Rai Penta: Mizrab benefits from Rai Penta’s accuracy and detailed imaging, the same opening finger cymbals exude stunning realism, sounding as if they’re inches away from the listener’s seat. The recording space becomes more apparent and defined. The same annoying live music attendees who yammer endlessly walked the earth in 1967, you can hear them in the background while the band coaxes Mizrab along its sinuous path. Its a mesmerizing listen, with a touch less warmth than with Advar but in no way less satisfying.

The Verdict:

Meze occupies a singular position among audio manufacturers. Their passion for innovation and “no-compromise” quest for perfection drives their every decision. It isn’t hollow marketing copy; it’s confirmed by the four mouse scrolls it takes to get through the accolades listed on their home page. Their engineering acumen, choice of materials, precision craftsmanship, and build quality testify to their dedication to excellence. Attention to detail extends to the most minute elements of their products.

Advar and Rai Penta demonstrate individual strengths and have uniquely tuned voices that gelled exceptionally well with the demo tracks we selected – and everything else we played through them. They’re pieces of sound art, designed to reveal subtle details with warmth and incredible accuracy that are built for a lifetime of enjoyment. If you’re in the market for a premium set of in-ear monitors that are comfortable and boast unrivaled sound quality they deserve your consideration. Surprising intricacies are waiting for discovery in your favorite songs, hear them again for the first time.

Additional Observations of Note:

Selecting the best-fitting ear tip is essential to getting optimal sound and isolation from both Advar and Rai Penta. Experiment with the provided ear tips until you find the one that offers a snug fit. Advar seemed a bit thin in the Low/Mid Bass until I found the correct ear tip – once found, the frequency response was lush and full.
The MMCX connection on the Advar doesn’t fit as snuggly with the flange as it does with Rai Penta. There was no discernable loss of imaging or detail, but it creates the impression that it is not completely seated.
