Meze Audio Poet Rinaro Isodynamic® Hybrid Array Headphone
June 14, 2026 § Leave a comment
If you are looking for a luxury headphone in this range that offers fine design, solid build, exceptional comfort, and sustainability, the Poet should be on the list for audition. Texture and tone are fantastic, across the spectrum. In comparison to similar designs, its center of gravity is lower, and somewhat contained by its smaller driver, earcup, and pad design. Resolution is on a par with others in this category, and dynamic expression is agile, refined, and consistently delivers the feel of our favorite performances, regardless of the fare. Meze has a sophisticated voice in the Poet.

STAX SR-009D Earspeaker $2,890 Review

Though the synergy with the SRM-700T energizer was spectacular, the SR-009D cable is a standard 5-pin design and will work with any other 580V Pro bias electrostatic amplifier on the market. Using STAX’s own SRM-D10ll portable driver, which retails for $945.00 and which I’ve reviewed and can recommend highly, can liberate the SR-009D from the desktop and can play up to DSD128 music files.
STAX is held in an almost mythical regard by audiophiles who seek the holy grail of the perfect reproduction of music, though it may never be possible to capture that enchanting goal. And STAX has competition these days, ironically because it was STAX that brought the magic of their earspeakers to the audio world and inspired other companies to reach for that elusive sound. We all benefit as these companies strive to reach the gold, but STAX is not resting on its exalted history; it is clearly continuing to innovate as the SR-009D clearly demonstrates.

The Signature S550 comes standard with Grado’s new B cushions and remains compatible with the full Grado cushion lineup, allowing listeners to tailor both comfort and sonic presentation to their individual preference. Like all headphones in the Signature Line, the S550 utilizes Grado’s Signature headband assembly. Integrated within the leather headband is a flexible metal support that allows the fit to be gently adjusted, enabling listeners to fine-tune how the headphone rests on the head and personalize comfort over time based on individual listening habits.
The S550 features the narrower leather headband strap, as used on the S750, and incorporates engraved metal gimbals, stainless-steel height rods, reinforced junction blocks, and controlled housing rotation to ensure durability, stability, and long-term comfort during extended listening sessions.

ES LAB ES-2a Review

Some people really don’t like that, so do try the headphone on first. For me personally this isn’t an issue with any of the filters, but they’re very close. Another thing some might find annoying is the driver flex. While normal and completely acceptable, you will experience this when putting the headphones on/off or adjusting them.
This headphone is one that you’ll be using at home or in your office in quiet environments as all the music leaks out and every single noise will crawl in. The ES-2a does need an EST amplifier and those usually are not portable either. The ES-2a comes with a hardwired 2.3m cable, so you do have a good range from your amp.

GRADO Signature S750 Open Air Dynamic Headphones $1,695 Review
February 1, 2026 Comments Off on GRADO Signature S750 Open Air Dynamic Headphones $1,695 Review
With the S750 Grado has well earned their Product of the Year Award and I’ll repeat my comment of then; representing the entry level for Grado’s Signature series of headphones, with the audiophile timbre, extreme efficiency, and dynamic range that denotes the Grado sound, the Grado Signature S750 has a unique subsonic heavy tonal balance that resonates with old Delta-Blues recordings, giving them a more modern feel. Jazz fans will love the liquid mid-range vocal reproduction, and Progressive Rock and Pipe Organ fans will adore the pulsating subsonics. And let’s not forget speed that is a rarity in dynamic headphones. Simply another gem from Grado, congrats.

ZMF headphones imo look like classic headphones with big cups and a regular looking head band. The design is simple but nice, and I for one like the way they look and feel. The detail of the ORI 3.0 logo on the headband is so well done.
ZMF headphones are hand‑built. The ORI 3.0 is machined in their state-of-the-art headphone CNC shop in Collinsville, IL. The Torrefied (Black) Limba and hand assembly happens just outside of Chicago in Berwyn, IL.
Each ORI 3.0 comes with lifetime driver warranty and everything is built to be serviceable with longterm parts support from ZMF. If anything’s off, reach out and they’ll make it right
