With knowing 64 Audio’s two top offerings in custom shape, the A18t and A12t, and the price of Fourté, my expectations were quite high before I received this monitor. Of course, for 3600$ you expect the monitor to sound like nothing else on the market. I was really intrigued by the fact that the Fourté does not use any dampers or tubes. I am a big fan of the tiatm treble’s energy and presentation. An IEM that uses two tiatm drivers and is complemented by a dynamic driver and a dedicated high-mid driver? Must sound great, right? Alrighty then, let’s find out.
The low end driver does a fantastic job reproducing a visceral and impactful bass. It extends well into sub-bass with decent rumble. The driver gives great resolution and texture to the bass, it sounds nicely organic and natural with good speed and accuracy. Especially instrumental pieces sound fabulous, but don’t be afraid if you’re a fan of synthetic punch, you’re taken care of with the Fourté as well. Bass is controlled and doesn’t overshine the transparency of the mids. There is a good boost in mid-bass and upper-bass gives lower mids a nice touch of warmth, yet not to an extent where they become overly fattened or too warm. What I like in particular about the Fourté’s bass is the air that surrounds it, it makes it sound very inherent. It also has wonderful power, drive and authority with the right tracks.
Mids are well smoothed and transparent, with a wide and deep stage that goes far beyond your head with the right recordings. I really like to listen to live albums with the Fourté as it perfectly shows its abilities to paint a realistic picture with pinpoint imaging. Midrange is held quite neutral with slight warmth in the lower registers, as mentioned before. Vocals are perfectly centered and instruments appear in good distance in front of you. All notes carry good weight, body leans towards a lighter presentation yet Fourté still retains the ability to catch all emotions in a recording. The Fourté has wonderful resolution and rendering, it’s like listening to a 4K screen. Everything gets separated so well, so clear and clean.
The treble of the Fourté gets discussed a lot for its more forward tuning. Treble is something you either can handle or you can’t. Myself, I like treble with good energy, and the Fourté does not disappoint. Highs are very extended and airy, but are not sharp or edgy. The tiatm treble is something quite unique with its crystal clean yet silky presentation. I see why some people have problems with the treble of Fourté, as the hyper clean sound of it can become too much for someone who isn’t used to it.
It truly amazes me how easily the Fourté reproduces every single note of each track I fire through it. Nothing gets overshadowed, everything is just there and sounds perfectly clean with incredible separation. People who want a monitor they can just kick back with might not enjoy the Fourté and its highly resolving nature. For me, it is spectacular and leaves almost nothing to be desired.
Depending on how you want to shape the sound of Fourté you have a good number of choices for aftermarket cables. You want those highs smoothened out? There are a few choices of good and affordable cables you can look into. You want to push it all to its absolute limits? There’s something for you too. Below you will find a small selection of cables that I paired Fourté with and felt the results were astonishing.
Effect Audio – Ares II (Bespoke 8 wire)
The Ares II adds a good portion of warmth and body to the midrange while straightening the bass response with a tighter grip. The Fourté still retains it’s clean sound and transparency, treble gets softened out a bit without losing its sparkle. Sub-bass gets a touch more pronunciation and a bit more forward. Vocals and instruments become more emotional and fuller.
Effect Audio – Leonidas
Leonidas would be the cable for you if you want to push Fourté to its very limits. The sound gets even cleaner with higher rendering. Bass gets tightened with a harder punch. Mids get some warmth in the lower registers breathen in, while some additional smoothness is received at the rest. Everything becomes more holographic and open. Micro detailing is achieved at an even higher level with insane transparency. Treble keeps its energetic appearance while adding a touch of sparkle.
The X has been one of my go-to cables for the Fourté. It beefs up the low end, while keeping it more under control. It doesn’t necessarily alter the midrange response, but lowers the treble to a more mainstream degree. It irons out a bit of the top end bite and energy. On top of that, it is the most portable cable I have in my inventory with its dual-wire build.
plusSound – Exo (Gold Plated Silver)
The GPS Exo is another good example of how to get the Fourté to its extremes. It tightens bass, opens up the midrange and adds some smoothness to them, while enhancing upper mid richness and top end clarity. It doesn’t kill some of the resolution and separation, but keeps them pretty much in tact as they were.
plusSound – X8 (Tri-Copper)
The Tri-Copper is an one-of-a-kind cable with its tripple Copper wire variants. It uses silver-plated, gold-plated and plain Copper wires for a unique signature. The lifted lower end and harmonious midrange will make a wonderful pairing with the Fourté, while upper mids and treble become a tad richer yet less bright. This is a great example of how to make Fourté more accessible for people who didn’t like the resolving energy of it.
My personal favourites for the Fourté are Leonidas and the Tri-Copper.
