MAFORER PV1 CD player Magnetic Levitation Professional Home HIFI CD Player

The team has been researching and developing for six years, and the magnetic levitation technology is applied to the latest PV1 series. This technology simply means that the chassis is suspended for operation, which greatly reduces the interference of resonance on the laser head reading, and the overall harmonic vibration speed and amplitude are significantly lower, so as to operate more stably and reduce noise.

Its main component is magnetic suspension vibration proof foot pin, and the diameter of a single bottom contact surface reaches 45mm, which is the largest of all electronic tube CD players at present! The four corners at the bottom of the chassis shell are respectively equipped with a foot structure, which includes an outer foot pad and an inner foot pad. The outer foot pad and the inner foot pad are vertically sliding together and can be close to or away from each other. The outer foot pad is equipped with a first magnet, and the inner foot pad is equipped with a second magnet that repels the first magnet. This design improves the vibration avoidance performance through mutual repulsion of magnets. This vibration avoidance structure can reduce the interference to audio equipment, so as to greatly improve the clarity and details of sound. There are two such structures inside, one at the top and one at the bottom, which can further reduce the vibration transmission and make the equipment free from vibration interference. Because the CD player vibrates greatly during operation, the sound should be significantly changed after magnetic suspension vibration avoidance.

The laboratory specially tested the frequency. The report from the NRC showed that through the frequency response detected in the silent chamber, it was confirmed that PV1 pin and ordinary pin did not change any original frequency response performance when reading discs; It is confirmed that PV1 can reduce the conduction of resonance energy; Compared with the general metal pointed cone, the vibration amplitude is significantly lower.

Test comparison chart:

PV1 is equipped with two imported 6h3 tubes. The professional electronic tube testing instrument implements high-precision and accurate matching. The anode coating with unique formula of this bile duct is more stable and durable with higher screen consumption. Rhodium plated tube needle is adopted to ensure the welding performance and contact performance. The ceramic base plate is non hygroscopic, high voltage resistance and high insulation, ensuring the high stability of quality; PV1 with electronic tube has a unique sound quality. It sounds sticky, warm and rich, with obvious overtone. It can clearly hear the characteristics of the warm and soft voice and the hazy feeling of the pipa. It can make a transparent, warm, detailed and smooth voice, showing a clean, delicate and rational taste. The analysis is very good, the details are obvious, and the presentation of the music level is very clear.

Lively and affectionate music

Positioning and rational timbre are its biggest advantages

PV1 gathers hifi class imported electronic components combined with precision circuit design. For the first time, the innovative magnetic suspension structure chassis is added with zero interference

PV1 has a comfortable musical smoothness, natural, smooth and elegant timbre, outstanding temperament, fine beauty of timbre, and fineness of middle and high-frequency tail rhyme, while the performance of middle and low-frequency does not deliberately add materials, which naturally presents the nature of recording, and has a thick taste of musical analogy. The interpretation of music is neutral and true, without too much proclivity. It is suitable for playing any type of music. If you like full, moist and lasting music, you will not be disappointed if you choose it!

Simple and elegant appearance

PV1 is extremely simple and modern in appearance, with suspended chassis design, simple and heavy

The front edge of the thick panel is slightly raised into an arc, and several layers of concave convex design add a three-dimensional sense. The lines, fonts and display screen on the panel are harmonious and comfortable. The left-right push-pull design of the overhead CD compartment gives a sense of ceremony, and the overall operation experience is smooth and natural without any

It has a rough feeling. It eliminates the common problem of replacing the old CD player with a belt.

American BB operational amplifier [opa2604]

PV1 operational amplifier uses the American BURR-BROWN company's opa-2604 as a high-quality filter circuit to completely filter out the digital signal and restore the pure and beautiful music signal. The sound is mellow, mellow, neutral and warm, and has a strong bile flavor. Opa-2601 low noise FET input circuit provides a large dynamic range and a very small offset voltage. The working voltage range can be from ± 4.5V to ± 24.0V, the distortion is only 0.0003% at 1kHz, the conversion rate is 25v/ms, and the gain bandwidth is 20MHz. It has low distortion, low noise, high signal-to-noise ratio and high bandwidth, and is widely used in high-quality audio circuits and other circuits that need first-class dynamic performance.

Precise frequency rise Technology

 PV1  has excellent frequency rise processing function, which can raise the frequency of 44.1KHz CD signal to a higher frequency. In order to reduce unnecessary errors in the frequency rise processing process, it is set to increase the frequency in integral multiples, namely 88.2khz and 176.4khz. Of course, friends who don't like the frequency rise can also turn it off. The function is hidden in the "display" key. Its indicators are excellent, and the sound quality is recognized by many large manufacturers: the dynamic range is up to 132dB, and the total harmonic distortion is low, which can be up to 300004%, so that the restored audio signal is closer to the original analog signal waveform, and the digital sound is completely removed, so that the timbre is directly forced to LP analog record player.

PV1 is a CD player that has been carefully designed in all aspects. Whether in the rigor of power supply design, or in the ingenious combination of analog circuits with modern operational amplifiers and high-quality electronic tubes, it has shown a very high level. The sound performance and appearance complement each other, showing the characteristics of soft and durable hearing.

PV1 true fully balanced output

Many machines in the market are false balance. How to distinguish the true from the false? The so-called false balance is that after the signal is input to the machine, the circuit is converted into unbalanced input for amplification. The true balance is that the CD player is balanced amplification from input to output to power amplifier. This power amplifier has a higher level of sound because the number of circuits is twice that of the ordinary unbalanced power amplifier. In terms of the dynamics of sound and the fineness of medium and high frequencies, the balance is much better, from decoding output digital filtering to

The gallbladder audio amplification output is a balanced line, reaching a true balanced value, with strong anti-interference ability, making the sound background cleaner and more exquisite, and the sound more gorgeous and atmospheric. The human voice is thicker and fuller through the gallbladder amplifier, making people linger on!

HiFi level external independent gallbladder op amp input

PV1 uses an independent operational amplifier circuit board to play with hifi friends' PC equipment. You can use Bluetooth on your mobile phone (you need to add a Bluetooth receiver), IPAD, The computer and hard disk use the lotus audio cable to input linein. The sound can achieve non-destructive effect, up to 24bit. The analog op amp output sound is more delicate and clean, the voice is sweet, and the background is quiet. It is not comparable with the USB input of ordinary machines.

Made from hundreds of test tunes

After countless component selections, the circuit design was refined to the connecting line in the machine, which was applied only after the team continuously debugged and auditioned. Instead of winning with speed and excitement, it brings users a comfortable experience of listening for a long time through real music restoration and aptamer, which can improve and optimize the details and luster of the sound, and fully overcome everyone's pursuit of advanced feeling. In any case, PV1 is a reliable and natural sound source device, which provides a solid sound quality guarantee for the universal sound system. Just as its simple appearance conveys, this CD player has great voice expressive power under its seemingly plain appearance.
