FUGAKU's greatest feature
It is three hybrid drivers and full analog multi-amplifier system.

The left figure below shows a conventional system and the right is a simplified example of FUGAKU's multi-amplifier system.

The conventional method is amplifier → passive filter → driver, in that order,
FUGAKU's method is active filter → amplifier → driver, in that order.

In conventional systems, there is a passive filter, a circuit for bandwidth division, between the amplifier and the driver, and the amplifier cannot drive the driver directly, resulting in a loss of directness in the sound.

In addition, passive filters must be small to fit into the earphone housing, resulting in a simplified design.
As a result, it becomes difficult to make the frequency response ideal for the designer.

There are several other negative factors in sound quality in exchange for versatility, such as the fact that a single amplifier drives multiple drivers, so the more drivers you add, the lower the impedance, the higher the load on the amplifier, and the more prone to distortion.

To overcome these problems, FUGAKU has adopted a multi-amplifier system.
This is a method that has existed in the speaker world for a long time in a small number of cases.

This is the world's first hybrid-driver earphone and full-analog multi-amplifier configuration, which first divides the bandwidth and then drives each driver with an amplifier prepared for each band.

It is no longer necessary to fit the filter into the earphone housing, and a sophisticated active filter consisting of an OPAMP can be used.

As a result, even higher-order steep filters can be built, and the frequency response that most affects sound quality can be freely designed.
In addition, the ability to use large volumes of high-quality components with large volume, such as film capacitors, makes it possible to achieve high quality on a component-by-component basis.

Not only that, but since the amplifier and driver are directly connected, the driving power is high, enabling unprecedentedly direct sound.
Another advantage is that as the number of drivers increases, so does the number of amplifiers, resulting in a lighter load per amplifier and less distortion.

The supposed disadvantages of this method are the reverse of the advantages of the conventional method.

This method requires a dedicated amplifier and a dedicated multi-pole cable, which reduces versatility and increases cost, but the sound quality benefits greatly outweigh the cost.

While a multi-amp system for speakers requires a separate preamplifier, active filter, and multiple power amplifiers, FUGAKU combines these components in a single housing to provide the ultimate sound on a scale equivalent to a conventional player + portable amplifier combination.

Back in 2010 i purchased the jerry harvey audio jh-3a $1748.00 usd (which appears to be the same thing)
$1.7k vs 18k
Oh my have price’s gone up
I hope no one buys it. They can't keep getting away with it.

Yeah no. I'd love to know how many products at this price sell. Obviously enough to keep doing it. Or the markup is just soooo inflated. Definitely the latter

this product is marketed for audiophools with deep deep pockets,that have their own printing press,to print money!
i actually admire brise audio,for creating a product that cost's maybe $1000.00 to create and sell for $18000.00
they obviously have people who will pay their price...
lol.. Actually, given how small this unit is my concern would be either misplacing or losing it. 🙄

Yeah would be a real bummer leaving that behind on the bus

Sure would! Of course with an item this expensive it would
be wise to carry insurance on it. 👍

FUGAKU is being manufactured.

We are currently manufacturing the first shipment of FUGAKU.

After assembling the earphones, we check the acoustic characteristics of each one to identify any variations.

We test the amplifiers using the Audio Precision APx555B on a wide range of items, and then assemble the ones that pass in the next process.

The amplifiers have a circuit built in to correct variations in the earphones, and each one is corrected by hand.

Through rigorous correction, the difference between the left and right channels and the error within the audible range from the reference curve are kept within ±0.83dB.

After that, two engineers check the sound quality, and if the appearance inspection is passed, the same serial number is engraved on the earphones and the amplifier.
