Introducing Kryna D-PROP!prop（ディープロップ）

Groundbreaking Quality Improvement with our Original Technique "Double Spike Receptacles & Liquid Containment"

Among many spike-type insulators, D-PROP is a real breakthrough.

Typically, spike receptacles are separate from their container and need to be correctly set in it. Originally provided with spike receptacles in the container, as the figure shows, D-PROP is simple-structured with high precision.

Based on a proprietary technology "Vibration Control Device" (patent applicant: Hiroshima TLO at Hiroshima Industrial Promotion Organization) developed by Prof. Kiminobu Nishimura (Kinki University) and Ryukei Ina (KRYNA President and CEO), D-PROP was developed with our professional expertise. We proudly provide this product: two spikes in the brass container filled with special liquid, resulting in a dramatic improvement in insulation. It is especially effective in controlling microvibrations and harmonic distortion that affect the sound.

Customers say, "Excellent signal-to-noise ratio," "There is no hissing noise and the sound is really clear," "It's realistic just like a live show," "With dynamic three-dimensional sound environment, it's really impressive," and "It's also effective for visual devices." And audio magazines carried favorable articles on D-PROP.

Although being spike-shaped, it does not catch the rack or anything but is easy to keep the equipment stable. D-PROP is an amazing breakthrough with its high quality and ease of use. It is an ultimate product to optimize the performance of your equipment.

D-PROP Excellence Demonstrated by Measurement

D-PROP excellence is demonstrated by measurement. Here's an experiment with a loudspeaker. There is a significant difference in harmonic vibration depending on whether or not D-PROP is used for the equipment. Since it can eliminate higher-order (second-, third- and forth-order) harmonic distortion, there is no hissing and other unwanted noises and sound coloration. D-PROP helps reproduce the original, clear sound.

It is effective for disk players and amplifiers as well as visual devices.

D-PROP is an academic invention and its excellence has been academically demonstrated.

D-PROP's groundbreaking vibration-control technology: its Advanced, High-Precision Mechanism

Then, what mechanism D-PROP has? Although we cannot give a detailed description, a brief one is this: in a disc player and other equipment, harmonic signals are distorted due to inner vibrations. Usually, the spike absorbs and removes the vibrations but not completely. A squealing sound at contact points is another problem. And a perfect solution to such problems is the hermetically-closed D-PROP with double spike receptacles.

As if it had many filters, D-PROP reduces vibrations from the top when they go through the first spike and the rest ones reach the second spike. In the process, the vibrations are damped by special liquid and consequently the vibration energy is almost completely removed. The heavy brass body (268g) is also effective in reducing vibrations.

D-PROP is doubly or triply effective.

D-PROP's Marked Improvements in Sound Quality

Specific improvements in sound quality are as follows:

1)      Clear, penetrating sound by reducing harmonic distortion

Lower-register sounds are beautiful and pure sounds are reproduced with no hissing and other unwanted noises and sound coloration.

2)      Clear Sound-Source Localization

Vocal and instrumental sound images are clear and their depth, height and direction are also reproduced. You’ll feel as if the sound penetrated the speaker without any obstacle. It is exactly the reproduction of a three-dimensional sound environment.

3)      Accurate & Natural Reproduction of Sound Environments

Its accurate stereophonic reproduction of sounds will give you the original recording atmosphere. Because of its excellent high-frequency response, it can be used for high-specification formats like SACD and DVD-Audio.

Effective Use of D-PROP 

D-PROP is effective for vibration-generating equipment such as a disc player and a loudspeaker and also for all audio/visual equipment with its power supply or chassis having vibrations.

1. Players: CD/SACD/DVD digital players as well as analogue players
2. Loudspeakers
3. Amplifiers and D/A converters
4. Power supplies
5. Projection equipment

Recommended Use

One D-PROP package contains three units (load weight: 40 to 50kg; recommended load weight per unit: below 15kg); D-PROP is safely used for heavy power amplifiers and loudspeakers. The equipment is held at three points. Unlike typical insulators whose package contains spike receptacles and the container separately, D-PROP keeps the equipment secure and stable. 

Recommended ways of use are as follow:
dprop

	1. CD Player Well-balanced three-point support; Eliminates unwanted noise due to microvibrations; Penetrating sound & dynamic three-dimensional sound environment
	2. DVD & Universal Player Clear color contrast and tones in images; accurate, vivid and exciting reproduction with a 5.1-ch DVD player
	3. Analog Player Especially effective for delicate analogue players; Lower-register sounds are all the more beautiful because of reproducing all information stored in the groove
	4. Speaker Real-time elimination of vibrations in a speaker unit or enclosure; Excellent, realistic stereophonic reproduction; far- and near-field sound-source localization; sound-source localization up to the height of ceiling
	5. Premain Amp & Power Amplifier Vibrations also affect amplifiers; D-PROP removes shadowy hiss, blurry drone and other unwanted noises; Pure and vivid sounds
	6. Projector High precision is absolutely essential for a full HD projector; sharply-focused high-vision images with pure colors are really impressive
	7. Sony PS-3 Damps vibrations; ideal for PS3's optimal performance; more accurate, more natural three-dimensional images; impressively clear sound quality
