Musicnote CD-MU15 Compact Disc Player Hifi Bluetooth CD Player with Push Cover and Remote Control

Description:
CD-MU15 is a professional audiophile CD player. It is the culmination of 20 years of experience of engineers.

Its large aluminum alloy panel, high-gloss acrylic and transparent crystal material make the machine look stable, elegant and classical. The top push cover design has a sliding structure with a sliding shaft, which has a good feel, stability, and smooth movement, improving the effect by one level compared to the non sliding shaft structure. The thick three-layer transparent crystal sliding cover adds more luxury and nobility.

CD-MU15 uses dual ES9038Q2M chip supporting 768K for decoding, one piece for each channel, which makes the whole machine more analytical. It uses 4pcs OPA604 op amps, and high-quality capacitors for Philips, Rubycon, etc. WE5755 tubes are used. The overall high-frequency slender hall is rich, the mid-frequency is full and smooth and sweet, the low-frequency dive is deep and flexible, and the control is good and will not be muddy.

The servo uses the CD servo system (SAA7824) for Philips: the CD servo system can only read CD format discs, different from the DVD system which is compatible with MP3 format discs.

The disc reading system is a new original CD mechanism for Sony, which is fast and stable with better details. The anti-vibration system adopts multi-stage shock absorption: damping glue, spring and bakelite material for shock absorption. The shock absorber made of bakelite material can prevent the shock of the shock suspension system during the movement, and the shock absorption effect is quite obvious.

The power supply adopts double transformers to supply independent power to the digital circuit and the analog circuit respectively, which effectively reduces the interference of the digital circuit to the analog circuit. The transformer is made from imported Z11 iron core and high-purity copper wire. The high-efficiency power supply provides sufficient energy for the CD player, so that the sound of the CD player is full, the low frequency is deeper, and the elasticity is better. In order to minimize the vibration of the transformer, the transformer is potted with full resin, which makes the machine run quieter and effectively protects the transformer. In addition, we also make magnetic shielding and electrical shielding of interference clutter for the transformer, and two sets of transformers are magnetically shielded with metal covers, and a layer of copper is plated on the metal cover for the electrical shielding of interference clutter. The CD mechanism is more sensitive to magnetic interference, and the servo appliance is more sensitive to electrical signal interference, so we believe that every design of the transformer is very necessary.

The disc player uses WE5755 tubes. The tube sound for Western Electric (WE) is recognized by audiophiles, and WE is also the brand pursued by the vast majority of audiophiles. The WE5755 are used as the main amplification. As as result, the high-frequency sound is slender and extended, the mid-frequency sound is full and sweet, and the low-frequency sound is mellow and deep. The overall sense of space is good and the positioning is accurate, which makes people feel immersive. The output stage is also designed with a set of output-specific modules, which reduces the output impedance in the machine by more than 10 times. So that you don't need to think about the input impedance matching problem of the power amplifier.

There are coaxial and Bluetooth input ports, and Bluetooth adopts a powerful CSR8675 chip. The chip has fast transmission capacity and supports high-definition audio format transmission, which is decoded by the CD player. It is an indispensable partner for listening to high-definition lossless music. The coaxial port can be connected to the digital output of the turntable, and the CD player can be used as a high-end decoder, which is quite good.

It uses a GPS-grade thermostatic clock and the most high-end femtosecond clock processing chip available. The clock signal can reach femtosecond-grade plus or minus 0.01PPM (plus or minus 20PPM-50PPM for ordinary clocks). Although the cost of the clock has increased, the performance of the system's details can be improved, the sound stage is looser, the background is cleaner, and the positioning is more accurate. The results are immediate.

More details: Round aluminum buttons provide good hand feel. The shell is designed with holes for the heat dissipation of the tubes. There are quality gold-plated terminals and transparent protective sleeves for the terminals.
