ZMF Eikon & Atticus

I've had the pleasure to hear many different closed back headphones over the years, the Mr. Speakers Mad Dog modded T50RPs were my first back in 2012. At that time I felt they were too thick and dark, so I sold them and started my addiction for closed back wood headphones with an Audio Technica W1000X. There was something magical about the sound, I later figured that it was the unique resonance of the wood that added a very real timbre to not only the W1000X but many of the other closed wood backs I would own.

Since then I've had a number of both stock and modded wood backs. Ranging from an amazing sounding Lawton Modded Denon D5000, to Denon's own AH A100. Each of them unique and with a beautiful sound signature. While my LA D5000 rivaled my HE 4 in clarity, it was still... lacking. It was a bit leaky, and the isolation wasn't amazing so I wound up selling it. As it didn't offer the isolation I needed so I just continued to use my HE 4 regularly.

Fast forward to now, being a married man, an open back headphone was no longer sufficient. As my wife didn't want to hear the music I was listening to! I returned to needing a closed back that had both the clarity I expected and true isolation. A solution that would only be heard by whom ever wore it, music just for a single set of ears. Having read about ZMF headphones a number of times over the years I was always curious how they sounded. They were well received and featured custom built wood housing around modded T50RP drivers, my interest was immediately piqued. Sadly though I never got to hear any of ZMF's modded T50RP's. I was fortunate enough to start my ZMF experience with Zach's newest in house Dynamics. No longer just selling a "modded" headphone, ZMF Headphones now have their own hand built headphones! Using a driver they developed and wood driver housing they built and designed.

I received two samples from ZMF to listen to, the Eikon in Cherry and the Atticus in Padauk. I was not compensated for my thoughts on either of these. An each can be purchased via their website

The Atticus and Eikon both arrived shipped in their own Pelican Case, padded on the inside and water resistant. I appreciate the decision made by ZMF Headphones to have such practical storage included. The box they came in had practically no information about the headphone aside from the ZMF Logo, which is also featured on the case it self. 

The padding inside was placed without any kind of glue or adhesive. Which allowed me to easily adjust the thickness of the padding to accommodate other equipment placed within the case.

It didn't have any accessories either, just the cable and the headphones. I had an option for cable termination as well, I choose one to be terminated with a 6.5mm output and the other with a 4pin XLR. The stock cable was well built, flexible with a good weight with a matching mini 4pin XLR mounted at the base of the driver housing. Which is excellent! As I have dozens of my own mini 4pin XLR cables to use in place of the stock cable. With so many manufacturers going with modular cables, I'm truly appreciative that ZMF choose the mini 4pin xlr over a standard 3.5mm. A wood owners card was also present within each of the cases as well.

Super thin, smooth, well trimmed on the edges and quite dense. Plus you can still appreciate the grain of the wood it was printed on. The rear side has a spot for your name. It's the little details like this that really set ZMF headphones apart from it's competitors. 

The build quality of each is impeccable. Everything is wood, leather or metal. Part of the appeal of wood back headphones is the build, and Zach's really gone above and beyond expectations! With that impeccable build does come a hefty weight. Switching into my Fostex TH X00 it's obvious how much heavier these are, though over the course of a few hours I don't have any fatigue.

The pads on each are a bit different, thicker pads on the Atticus give it a wider sound stage and a funner low end, while the slightly thinner Eikon Pads bring the drivers closer and improve on the imaging. Both are equally comfortable and the pads looks beautiful. Each set is well manufactured with tight seams and good flexibility to the leather.

A smooth range of motion is a continuous theme for the Eikon an Atticus. The headband adjusts nicely to the shape of my head and does an amazing job of supporting the weight of these headphones. 

The gimbals likewise have a smooth action to them, they hold the cans in place nicely and don't slip as much as you'd think they would. Likewise the cups swivel smoothly without an excessive range of motion. Best of all the pads while well attached to the housing, the pads can rotate a little, which makes keeping them aligned easy. Zach offers the gimbals in both a silver and black finish.

As a whole the construction is rock solid and beautiful to behold. Everything stitched together nicely and every hinge is completely silent. Add in the completely modular cable and ZMF Headphones defiantly set the standard for what I'd like to see from every manufacturer in this price range! 

The same attention to detail and quality in the build is evident in their sound. These two headphones sound phenomenal. In short, the Atticus brings a warm detailed sound with a beautiful mid range and very fun bass within a wide sound stage, where as the Eikon offers a deep detailed refined sound with a touch of warmth and very real to life imaging.
For my impressions I did build a system around the Eikon/Atticus. I ran them entirely though my Ember II running 35R out with a 1944 Sylvania 6sn7 GT white label bottom getter flash tall bottle tube. I also listened to each with an OCC Copper cable I had on hand. I found that with lower output resistance out of my Hybrid Tube the top end becomes metallic and overly edgy on each, energy and tactility is replaced by metallic clanking or banging, a higher output resistance made the sound overly soft and mushy. Running them out of my balanced solid state was better than using the wrong output impedance on my Hybrid Tube, I preferred High Gain with my Audio GD NFB10ES2. Although it really over drove the low end on both. It imparted even more power and slam into the bass, at the cost of some texture and resolve. Same with the highs, my solid state made them harder and more metallic. The Atticus though was more welcome to these changes than the Eikon however. 

The Eikon is more sensitive to both cable and amplifier changes, and suffers more from a the wrong pairing. The Atticus on the other hand really opens up with the right amp or cable and will not punish you for pairing it with the wrong one. Ultimately I achieved the most balanced presentation from both out of my Ember II running 35R out with my 1944 Sylvania 6sn7 GT. 

Mid range on each of these is breath taking, the Atticus has more decay an a touch more resonance in exchange for some of the Eikon's tactility. The inherently warm tone in the body of an instrument seeps out of the Atticus's euphoric presentation. Vocals have both clarity in the lips, mouth and breath with a distinct focus on the body. A captivating warmth from the chest and throat. The sweetness of harmonics pairs beautifully with clear fundamentals in stringed instruments both electric and acoustic. Thick with a precise slam when needed for clear imaging with heavier acoustics. The gentle touch of the body in smaller stringed instruments, and the perfect mix of crunch and creamy sweetness for both soft and heavy electric guitar riffs. Woodwinds and horns are presented with an articulate wetness followed by a beautifully voiced sustain and release. With the Atticus I found the body of the instrument to be in focus without over shadowing the rasp of a bow across string or the breath taken before a note is played. 

The Eikon how ever, doesn't bring the body into focus as much as the Atticus. Rather it brings a very realistic sense of tactility and presence in exchange for a less decay and resonance. A sharper image and faster transients pair with a polite warmth. Both headphones at their core bring out the warmth of the body, but the Eikon doesn't bring that warmth into focus. At it's core the Eikon's presentation has power in the low body resonance and fundamentals of an instrument alongside the tactility and presence of the strings, lips and breath. It's not quite as  beautiful or romantic as the Atticus, which gives it better clarity in very thick mix's. But is also less forgiving of poor recording techniques or mastering. Although different, I felt the mid range of each was technically equal. Ultimately preference will dictate which headphone is better in terms of the mid range presentation. 

Presentation in the lows is less a difference in preference and more about technicalities. The Eikon has a stronger low bass emphasis, fairly linear from 20-100hrz with a gentle slope from there. The Atticus on the other hand, has a prominent mid bass hump from 60-100 with a steeper slope. 

Incredible slam and a thickness to the body of instruments are what that mid bass hump add to the Atticus. The decay does hang a little an audible reverb is present in the bass, giving those low notes an gently evaluated sense of heft and weight. The cup reverb also both softens harder fundamentals and adds a touch of emphasis on harmonics. Riffs on a double bass had a thicker body, more of the instruments natural resonance was present. House Music had a great presentation of that driving rhythmic mid bass, though the bigger deep drops in Drum'n'Bass or Dub Step lacked a little. An I personally found the bass to be a touch excessive for around a fifth of the songs I played. Bigger drums like the Timpani can often be a touch boomy and a tad intrusive. While not lacking details in the low range presentation, clarity could be better. Fret and string noise is evident though often a little diffuse. 

In contrast, the Eikon proves much cleaner and faster throughout it's entire low range presentation. Going to the double bass, there's a sense of power from the sheer weight of the instrument, in addition to the warmth of the body. But unlike the Atticus, the Eikon's cleaner overall bass allows for a touch more detail to be present. Fret noise is more apparent than on the Atticus. This clarity pair'd with the low bass emphasis translates into a nice power. Low notes on a piano really hit you, kick dums slam hard and fast, even bigger drums like the timpani have well controlled boom and gusto. While not as much fun with House and other dance oriented genres of electronica, Drum'n'Bass and Dub Step have powerful, growling deep bass when needed. Finally, the bass at no point ever impede's with the presentation of transients throughout the entire spectrum. I can find no fault with the bass of the Eikon except for maybe being too "boring" for some. 

While the Eikon again brings better clarity and overall transients response in the highs, the Atticus does a bit better with micro detail up top. Not to say the Eikon is lacking, but some breath's, page turns and other top end micro detail is more apparent on the Atticus than it is through the Eikon. However, transients are resolved more clearly with the Eikon, warbling of bells and the release on strings are better defined. Both have excellent extension, with the Eikon having a sweeter more tactile top end and the Atticus bringing a more energetic though darker top end. Though the thicker midrange on the Atticus some times diminish resolve on the top end, unlike the Eikon which again remains exceptionally clear from top to bottom. 

Overall the Atticus presents contrast within it's presentation. Thick powerful lows with a darker but very lively top end. That 10kHrz peak adds a nice bit of energy and micro detail resolve to the beautiful mid range. I really loved the extra edge the Padauk adds as well, while not as balanced as the Cherry Eikon, the Atticus is very exciting! It's a tad more dynamic with it's mid range presentation which contributes to it's magic. The Atticus also presents a wider overall sound stage as well, which again only compliments the more forward mid range presentation. 

The Eikon on the other hand, has a more refined sound. Better resolve and tactility, faster transients, a blacker background, deeper more precise imaging and a powerful well controlled bass. While the sound stage isn't as wide as the Atticus, it's deeper, airy and more believable. The Eikon brings a sense of realism, in contrast to the more engaging euphoric sound of the Atticus. Though it's the little details that push the Eikon above it's brother in my eyes. 

I did wind up purchasing an Eikon for my self, as much as I loved my collection of wood backs the Eikon eclipsed them all. I've since sold my previous wood backs to enthusiast who'll hopefully enjoy them as much as I did! 

Though If I'd had the chance to listen to both three years ago I'd have chosen the Atticus for sure. It's sound really invites you into the music more as a whole, where as the Eikon's presentation is as much about the music as it is about the sound of the individual instruments as well as the process of capturing those instruments. Though, both at their core have a very natural inviting tone. Unlike my HE 4, the Eikon presents the same and in many cases better resolve, but it doesn't force those flaws in my face. These days it's the little details that really pull me in, and the Eikon's ability to politely present everything in a recording that is what I personally love about it. 

In the end I enjoyed both, I found that the Atticus better suits some one whose focus is on the music and not so much each individual piece of equipment in the play back chain. It scales nicely, but also maintains it's beautiful euphoric sound even with less than optimal set ups.  The Eikon on the other hand works best in a system that's been meticulously put together, the right amp, the right cable, the right digital audio converter and the right mastering all together with the Eikon make for an un-believe listening experience! 

Regardless of which philosophy you see hold your self to, both come with my full recommendation. Zach's customer service, build quality and attention to detail make these by far the best Wood Backs I've heard to date!

Denon AH A100

The baby Denon 7000 as it were, it's rumored to have had less than 1,000 total units in production. With no more than 400 being imported to the US. I was fortunate enough to find mine second hand, sadly by the time I'd gotten it the headband was replaced and the stock cable was swapped for a modular mini 4pin XLR. The previous owner even swapped out the ear pads, I held onto it for about a year with hopes to restore it, though I never got the time to do so.  

The packing is most impressive. With an MSRP of $499, I feel Denon set the BAR for how to present a product with this launch. The outbox is just cardboard, but inside the actual product box is encased in a faux leather with Denon logo embedded in a gold font.

Sadly, the box I had didn't age very well. I was the third owner of these so I didn't have much control in how they were kept prior to being in my possession. Still, even more impressive than the outside of the box was the linen lined interior! 

I owned the Denon 5000 and still have it's original packing. An sadly it's no comparison. It's a shame that Denon only offered this attention to detail and quality for it's 100th Anniversary headphone. Still again, this was only a $500 headphone when it was launched! Even today, and up into the $1000+ territory I've yet to find a box designed this beautifully and functionally. 

Although entirely in Japanese, I enjoyed reading through the booklet included with the AH A100. It apparently covers Denon history in the A/V Industry. 

Despite my certificate of authenticity, the status of a true collectors item was out of my reach. Having been modded for better comfort and function I decided to just sit back and actually listen to it! 


  • Dynamic Neodymuim 50mm driver
  • Frequncy Response 5-37,000 Hz
  • Sensitivity 101 dB
  • Impedance 32ohms
  • Weight 7oz

The overall sound is very balanced, with a warmer tilt and thicker timbre. They had neither a veil nor were super transparent and detail oriented. They just simply sounded good. The image was believable and intimate with impressive coherence but not super defined. Transients weren't super clear, but were neither totally absent. Both micro-detail and dynamics were also apparent, but not in your face obvious. My listening with these was sourced from my Project Ember II, running my Sylvania 6sn7 GT Jan-Chs VT 231 tube an straight out of my HM 601. 

The Denon AH A100 did suffer from a little sub bass roll off, but had good power and definition in the bass overall. While listening to Jazz the upright bass was presented with authority and just a touch of fret noise. Acoustic guitars have a touch of texture with a thick body and only little bit of mid bleed. Only kick drums suffer on the Denon AH A100. I found it lacked power for many of the metal tracks I listened to. For world music and classical bigger drums like the Timpani and various ethnic war drums had a good heavy presence more tactile than it was audible.

The Midrange was intimate with a touch of tactility. Guitars had thick body, and good crunch when needed both in the lower and upper mids. Heavier distorted metal riffs had a nice aggression without sounding too thin or thick. Vocals had a good touch of breathy echo up top and thick low registers. Good body and chest weight to the sound. Violins and wood winds, were a little lacking in presentation of their transients,  though had a warm sound with more emphasis on the body and resonance of the instrument, over the individual strings. That warm weight of the collective was very present throughout the mid range, it was especially nice with a piano. 

I liked the highs best on the Denon AH A100, good sizzle and snap. Lots of clarity, air and aggression without ever being too harsh or strident. A strident top end is common of the stock Denon D2/5/7 series, but the AH A100 has the energy without the harshness. Though, every so often the highs were tapered a bit behind a thick mid range.  

I compared these directly with my Modded Audio Technica ES10, and ultimately what I found was while my ATH ES10 had better definition, better imaging and with a faster more beautiful and natural timbre. Though it's flaws were just as obvious as it's strengths though, on the flip side, the Denon AH A100 was very relaxed has excellent comfort and is equally engaging. It isn't perfect, but it's flaws and strengths aren't as apparent. If anything, I can say it was a touch too slow and warm. Though the ATH ES10 I have has been modded to give it the speed and detail it has. The real strength of the Denon AH A100 though is it's balance. Unlike the Audio Technica ES 10, it's not picky about what you plug it into. It's not picky about what files your playing with it either. It simply exists, you wear it and you enjoy it. 

Overall the Denon AH A100 brought together the best elements of the larger D series, and combined them for an overall relaxing and pleasant listen in an easy to manage size packed in one of the BEST Headphone Boxes I've had a chance to own! These prove to be a real treat from Denon to the few who are fortunate to own one!
