Principle and structure

A block of 2017 Duralumin carved out housing!
RTP-2, 4 and 6 ultimate`s box is made from 2017 Duralumin, which has the best vibration declining characteristics and excellent sound quality.

A block of 2017 Duralumin has been carved out into a luxury structured box.

Comparison of metal materials vibration decrement characteristic

Block carved out structure has far better vibration declining characteristic, sound quality and less distortion compared with thick metal sheet bolted together into a box.

The boxes maximum thickness is 25mm, so not only it has a excellent vibration declining characteristic, it also total shut out any noise from getting inside, which lead to overwhelming S/N ratio.

A block of Duralumin weighs 3kg (6.6 Pounds) for RTP-2 ultimate, 4kg (8.8 Pounds) for RTP-4 ultimate and 6kg 13.2 Pounds) for RTP-6 ultimate.

A block is been carved out using a precision processing machine. It takes about 5 hours to carve out one block and lid for RTP-2 ultimate, 8 hours for RTP-4 ultimate and RTP-6 ultimate.

Eliminates noise and static electricity non-contact and non-magnetism!

RTP-2, 4 and 6 ultimate`s box is filled with Green carborundum, Tourmaline powder and natural quartz powder to eliminate noise and static electricity without no contact and non-magnetism.

Most of power supply box uses series type noise filter.

But series type filter transfers noise elements to heat by magnet which not only absorbs noise, it also absorbs important electrical energy.

Also the magnetic body produces magnetic distortion by the noise absorption which adds a distorted feel and thinness to the sound.

This is because an electromagnetic wave absorbent material itself is a strong magnetic body.

Also parallel type noise filter or choke coil can not avoid loss in transmission energy.

It eliminates noise buy it takes away feeling of restraint and energy feel from the sound.

Green carborundum has no side effects because it non-magnetic body.

It only absorbs electromagnetic wave noise which is produced from receptacles and internal wiring.

Green carborundum is the only electromagnetic wave absorbent material which improves sound quality and S/N ratio.

Also the Tourmaline powder releases negative ion and keep the amount static electricity very low.

The natural quartz powder releases far infrared rays which has an surface activation effect. This leads to very realistic and sound filled with a feeling of throbbing pulse.

Hear is the Duralumin block after it been carved out. After this it gets treated by Sand Blast Process and the surface gets by Snow White Alumite. The lid gets treated by Hair Line Process and on top that, the surface gets treated by Black Alumite.
Electro magnet absorbing material Green carborundum is placed inside the Snow White Alumite treated chassis.
Top quality Lithia tourmaline powder and natural quartz powder gets mixed into Epoxy resin. Instead of using industrial use black tourmaline, for RTP ultimate series, we Jewels uses top quality Lithia tourmaline which releases more negative ion.
Epoxy resin which contains Lithia tourmaline powder and natural quartz powder gets pored on the top of Green carborundum carefully.
Hear is the chassis which is set and pore with Green carborundum, Lithia tourmaline powder and natural quartz powder. The chassis is left for about a week for the epoxy resin to set.

Carved out brass foot with epoch-making vibration control material!

Underneath the RTP-2, 4 and 6 ultimate`s box, there are brass carved out large foot, white are height adjustable. Combination of 2017 Duralumin box and brass foot will eliminate both materials resonance frequency.

Comparison of metal materials vibration decrement characteristic

To further improve vibration control effect, the vibration control sheet in placed underneath the brass foot.

is a sound quality adjustment material developed by professor Masao Sumita at Tokyo Institute of Technology by getting a Pre-venture support from JST (Japan Science and Technology Agency).

is a epoch-making material and carries an overwhelming vibration control characteristic.

It transfers and eliminates vibration energy from electrical energy to heat energy.

Combination of Duralumin, brass and leads to the ultimate vibration control structure.


OYAIDE`s special version Beryllium copper electrode adopted R-1 for receptacle!

For RTP-2, 4 and 6 ultimate`s receptacles, we adopted the OYAIDE`S R-1 special version.

R-1`s electrode material is made from Beryllium copper, which has the best conduct characteristic.

The electrodes surface have been mirror polish finish to further improve conduct characteristic. We at ACOUSTIC REVIVE have changed the electrode parts to thick silver plating and thick rhodium plating which has the best conduct characteristic and phase characteristic and only the electrode parts have been Super cryogenic treated (-196oC) to improve conduct characteristic to the limit.

Most of Super cryogenic treated receptacles get treated by whole receptacles. But because the shrinkage rate is different, resin parts get damage and deteriorated and product and sound quality get destroyed badly. This is why we at ACOUSTIC REIVE only treat the conduct parts.

Parts inside the receptacle


The ultimate material for power supply inlet and internal wiring too!

We adopted the ultimate power supply inlet and internal wiring for RTP-2, 4 and 6 ultimate. Same as receptacles, power supply inlet has been Super cryogenic treated and treated with thick silver plating and thick rhodium plating.

The inlet wiring connection is non-solder. We at ACOUSTIC REVIVE does not adopt solder because it destroys transmission badly.

For internal wiring, we adopted the FURUKAWA Electrical Industry’s oval shaped very thick PCOCC-A which as the ultimate conduct characteristic. PCOCC-A is a annealed version of PCOCC (single crystal copper) manufactured by the high technology of FURUKAWA Electrical Industry.

Not only PCOCC-A has a better conduct characteristics then PCOCC (Please look at the PCOCC-A & PCOCC comparison list), because it originally is a single core crystal, the chance of impurities getting inside is very low even it gets annealed.

So at end it has a far better conduct characteristic and higher purity then high purity conductor such as 6N. This high conduct character PCOCC-A is made into oval shaped single core which has no peaky and distorted feel to sound quality compared with round, rectangle, flat shaped conductor.

Beautiful finish improving sound quality and keeping product quality in long term.

To keep the product quality and sound quality in long term, the 2017 Duralumin made box is treated top quality pear surfaced Snow White Aumite, and lid is treated with top quality Black Hair Line finish.

The brass food is treated with top quality mirror surface finish Chrome plating.

A product using non-surface treated Aluminum alloy and Brass releases rust which is harmful to human body, so please be careful.
