HiFi Components:
- Imported 6HC electronic tube for Soviet, with a strong early taste of electronic tubes.
- For ERSE capacitors from the United States, S-CAP high-end series.
- Oxygen free copper transformer, stable and smooth operation.
- For Nichicon/ELNA electrolytic capacitor.
- The most stable movement for Sanyo laser head currently.
- The first domestic application of magnetic levitation high-end spikes.

Magnetic levitation technology is applied to the latest PV1 series. Simply put, this technology allows the chassis to operate in a suspended position, minimizing the interference of resonance on the optical pickup unit's disc reading. The overall resonance speed and amplitude are significantly lower, resulting in more stable operation and reduced noise.

Its main component is the magnetic levitation anti vibration spike, with a single bottom contact surface diameter of 45MM, which is currently the largest among all electronic tube CD players! At the four corners of the bottom of the chassis shell, there are foot structures installed, which include outer and inner foot pads. The outer and inner foot pads slide vertically and can approach or move away from each other. A first magnet is installed on the outer foot pad, and a second magnet that opposes the first magnet is installed on the inner foot pad. This design improves the vibration isolation performance through the mutual repulsion of magnets. This vibration isolation structure can reduce interference with audio equipment, thereby significantly improving the clarity and details of sound. Inside, there are two layers of this structure, one above and one below, which can further reduce vibration transmission and prevent equipment from being affected by vibration interference. Due to the high vibration during the operation of the CD player, magnetic levitation vibration isolation should have a more significant impact on the sound.

According to the report from NRC, the frequency response measured in the anechoic chamber confirms that PV1 pins and regular pins do not change any of their original frequency response performance when reading discs; Confirming that PV1 can reduce the conduction of resonant energy; Compared to typical metal cones, the amplitude of vibration is significantly lower.

PV1 is paired with two imported 6H3 tubes, and professional electronic tube testing instruments are used for high-precision and precise matching. The unique formula of the anode coating on this electronic tube ensures higher screen consumption, stability, and durability. Rhodium plated tube needles are used to ensure welding and contact performance. The ceramic base plate does not absorb moisture, has high pressure resistance, and high insulation, ensuring highly stable quality; The sound of PV1 paired with electronic tubes has a unique sound characteristic, which sounds sticky, warm and rich, with obvious overtones. It is possible to clearly hear the warm and soft characteristics of the sound, as well as the hazy feeling. It emits a transparent, warm, delicate and smooth sound, presenting a clean, delicate, and rational feeling. The analysis is very good, the details are obvious, and the presentation of the musical level is very clear.

Spaced solid pure copper support movement: PV1 has undergone mechanical structural improvement, using 8 specially customized pure steel columns to independently support the entire movement. The shock absorption effect is very good, which can effectively reduce the resonance frequency and is more stable and smooth than traditional movements.

For SANYO high-end laser head: PV1 adopts for Sanyo series high-level laser head, which has strong disc reading ability and better stability. It is matched with a floating stainless steel movement, which is not affected by resonance interference and has a longer lifespan. The all black design of the inner compartment reduces light interference, and the outer arc of the disc holder stabilizes the airflow during disc rotation, without interfering with playback.

PV1 gathers a set of high-end imported components combined with precision circuit design, and for the first time adds an innovative magnetic levitation structure chassis with zero interference:
The PV1 electronic tube CD player has a comfortable music smoothness with a natural, smooth, and elegant tone, outstanding temperament, and delicate beauty in the tone. The delicacy of the mid to high frequency tail rhyme is not deliberately added to the performance of the mid to low frequency, naturally presenting the essence of recording and having a thick music analogy flavor. The interpretation of music is neutral and authentic, without too many quirks. It is suitable for playing any type of music, and there is no need to explain the electronic tube CD vocals. If you like a full, moist and charming tone, choosing it will not disappoint you!

The PV1 has an extremely simple and modern appearance, with a suspended chassis design that is simple, heavy, and steady. The craftsmanship is exquisite, and the details are polished smoothly. The thick panel edge is slightly raised into an arc shape, and several layers of concave convex design add a sense of three dimensionality. The lines, fonts, and display screen on the panel are harmoniously and comfortably matched. The top mounted CD compartment features a left and right sliding design, giving a sense of ceremony. The overall operating experience is smooth and natural, without any roughness, except for the common problem of changing belts in old-fashioned CD players.

The PV1 operational amplifier uses OPA-2604 as a high-quality filtering circuit to thoroughly filter out digital signals and restore pure and beautiful music signals. The sound tone is mellow, round, neutral and warm, with a strong electronic tube flavor. The OPA-2604 low-noise FET input circuit provides a large dynamic range and minimal offset voltage, with a working voltage range of ±4.5V to ±24.0V. The distortion is only 0.0003% at 1KHz, with a conversion rate of 25V/MS and a gain bandwidth of 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 require first-class dynamic performance.

Precision of 0.001%: They do not rely on external decorations to attract attention, with each craftsmanship meticulously crafted to a precision of 0.001mm, but rather prove their meaning through their intrinsic value. Simplicity is not simple, but a carefully considered refinement that leaves behind the core essence after removing unnecessary complexity. It is beneath this seemingly ordinary appearance that there is enduring power and true value.

PV1 has excellent up conversion processing capabilities, which can up convert 44.1kHz CD signals to higher frequencies. In order to reduce unnecessary errors introduced during the up conversion process, it is set to up convert by integer multiples, namely 88.2kHz and 176.4kHz. Of course, users who do not like to upgrade can also turn off this function, which is hidden in the "display" button.

PV1 is a CD player that has been carefully considered and designed in all aspects. It has demonstrated extremely high standards in both the rigor of power supply design and the clever combination of analog circuits with modern operational amplifiers and high-quality electronic tubes. The sound performance complements its appearance, exhibiting a soft and durable characteristic.

HiFi level external independent electronic tube operational amplifier input: PV1 uses a HiFi level independent operational amplifier circuit board, providing audiophiles with PC equipment gameplay. It can be used with mobile phone Bluetooth (Bluetooth receiver needs to be added), IPAD, the computer and hard drive use RCA audio cable input (LINE IN), which can achieve lossless sound effect, up to 24BIT. The analog operational amplifier output sound is more delicate and clean, with sweet vocals and quiet background, which is not comparable to ordinary machine USB input.

Built-in filtering power processing, quiet, clean and clear background: PV1 linear noise dissipation with eight degree AC differential filtering (20KHZ-1GHZ over 24DB), with linear response optimized for changing line and load impedance. AC RF filtering capacitors create better frequency response and reduce distortion. This technology completely eliminates the occurrence of cross interference caused by current.
