Now let’s take a look at the production and materials:

1: Chassis: Now high-end chassis are generally made of aluminum alloy, and E-700 power amplifier is also made of aluminum

CNC precision production, the punching position is correct, the panel wire drawing is delicate and smooth, the texture is beautiful

Clear printing and first-class technology.

2: Transformer: The 700W giant ring transformer is adopted, the iron core is made of A sheet, the interior is treated with dipping paint, and the cow barks are controlled. It is wound with pure copper, and it will not cut corners, nor will it be made of copper clad aluminum. We know that the brand is made by quality.

3: Filter power supply: 6 Japanese ELNA 10000UF/80V audio dedicated filter capacitors are used in the pond. Please note that they are dedicated to AUDIO audio. Not any capacitor can be used. The sound is different. The input and tone boards use high-precision bottom noise LM317/LM337 as the voltage regulator, not

78 series three terminal voltage stabilization, with completely different noise coefficients.

4: The protection circuit adopts the special protection chip 1237HA for audio power amplifier, the special chips A65 and P7100 for golden voice, which are also our special products for power amplifier. The inductance is wound with 2mm pure copper enamelled wire to protect the relay

The high quality original imported Omron 16A times high current product is adopted, and the quality is guaranteed.

5: Input switching adopts the original Japanese NEC relay EA2-5NU, whose contact impedance is negligible. It is known that pure mechanical switching has the least noise pollution, and the control is programmed by CPU

Control, do not touch the audio channel.

6: The power amplifier board with independent left and right channels is used to greatly improve the sound separation, so that the sound field becomes wider, dynamic becomes larger, the level is clear, and the three-dimensional sense of details is enhanced. Each channel adopts 8 "Ansome" pipes

The sound of the power tube (NJW1302/NJW3281) is very dense and grainy, and the density is also very high, but it feels just right. The sound is more mature, the low frequency sense is good, and the expansion is good

Moist and calm, very beautiful and charming. The control force of the pair of pipes is excellent, which belongs to the level of pipe king.

7: The super large built-in radiator is adopted. The upper and lower cover plates of the chassis are equipped with corresponding heat dissipation holes. The radiator is designed face to face. This can lead to "flue type" air convection, which greatly improves the heat dissipation effect. Because the hot air is rising, the cold air will naturally flow in from the bottom of the chassis, leading to convection, Another advantage of face to face placement of the radiator is that the heat from the radiator will not enter the chassis, but will flow out. Sometimes the details determine the success or failure.

8: The Japanese original ALPS potentiometer with motor is used, so the volume of this machine can be controlled remotely. Sitting on the sofa can control the volume, which is very convenient for enjoying music.

9: The AC "green clean" technology, which is developed exclusively by us, can filter out the DC ripple of the mains, make the music background darker and the sound cleaner.
