Firewall for Headphones new product release! Promotional price announcement!
Dear esteemed clients,
We are happy to announce the immediate availability of the latest product in our Firewall product family: the Firewall for Headphones current conditioning unit!
What does it do, and why do I need it?
This unit reduces invasive electro-magnetic noise like no other solution. If you want the purest, most musical, most deeply transparent window into your prized recordings, this unit is definitely for you. Simply plug it in between your headphone amp's 4-pin XLR output and your headphone's 4-pin cable. The Firewall for Headphones is a non-powered, passive device which acts only upon the HF noise, leaving the signal pure and untouched, protected from the detrimental audio smearing effects of HF invasive noise. This is no buzz & hum remover. Buzz & hum come from faulty parts or bad wiring schematics and are fixed by addressing those types of things directly. The Firewall for Headphones turns a great headphone listening experience into a profound headphone listening experience.
Don't just take our word for it
Independent reviewers have said of the Firewall for Headphones:
"easily demonstrable, surprisingly oomphy!"
"for the true connoisseur."
"Instantly notable"
"It allows us a deeper look into the ephemeral play of harmonics which give instruments their individual timbre."
"the apparent nothing of empty space becomes its own far-from-nothing entity."
"tighter bass, improved clarity, less grain and all virtual shapes rendered more precisely on a background that felt sensibly more pristine."
"free from any sonic downsides"
"Bass stripped from noise develops extra heft and fullness alright, but also becomes tighter and more powerful"
"The entire musical image grows larger and more robust, while edginess that causes listening fatigue vanishes. Unsurprisingly, the latest Firewall tailored for headphones follows this exact protocol to a tee. As such it introduces only audible gains."
"More body, less pointy outline edges, less sharpness and less textural gloss, then followed by beefier tighter bass, more pronounced meatier midrange and far superior highs, particularly on decay and smoothness."
"Today's Firewall also greatly boosts the sensation of aural space, so that it feels more breathing, moving and alive."
"The very last instrumental reverbs significantly easier to 'see' and appreciate."
"elevated immediacy, energy, bite and snap"
"I heard primarily smoother and more distinct vocals."
"Individual bits on this tune registered as more pronounced sounds, which were again easier to follow and focus on. In effect the entire track registered as a more romantic and sensual version of itself with the LessLoss."
"The bass dug deeper, claps had more snap and body to them, the vocal was more substantial and lifelike and spatial sizing grew noticeably larger. The song felt more intense, enveloping and grander."
Firewall for Headphones features exotic technologies you'll never find elsewhere!
Our high end designs go well beyond anything you have ever seen on the audio market. In-house technologies such as our own developed and built award-winning C-MARC™ cable, our award-winning Firewall technology created by direct laser metal sintering, potted in hardened clear epoxy resin in wooden housings, and our special Entropic Process conductor ageing processes all come together elegantly to create an absolute beast of a performer.
The housing is no less important, and we go all the way!
We build the unit around a precision milled solid brass frame. This frame is only formed on two axes to ensure that EM resonance of an enclosed metallic enclosure is not possible. This is the bane of many audiophile equipment solutions with the result that many users simply open their units' lids because they find the sound more natural. What they are doing as a result is reducing internal EM resonances, allowing much of the circuit-born emission to simply leave the confines of the enclosure instead of reflecting internally. Our solution goes many steps further, not only providing an electro-magnetically open base and top, but by strongly mating resin-infused Kraft paper composite material to all sides, bottom and top of the metallic brass frame. Due to the phenomenally quick resonance damping of this composite material, this stops even the most minute physical resonance of the enclosure dead in its tracks. We have never heard a better build material for audiophile purposes. This is truly the state-of-the-art today. Not even the bullet-proof Panzerholz technology from Germany comes close.
Input and Output
To use the Firewall for Headphones, simply connect your 4-pin XLR headphone amp's ouput to the 4-pin XLR input of the device. Then, connect your headphone cable's 4-pin XLR input plug to the 4-pin XLR output socket of the device.
For best results, always choose C-MARC™ Entropic Process cable.
We make the most advanced audio cable available, and highly recommend the use of the C-MARC™ Entropic Process 4-pin XLR cable to connect your amp's output to the Firewall for Headphone's input. The difference is meaningful and you will greatly appreciate the superb results of such a combination.
