Muse Deluxe 1.0 CD Player

Muse Deluxe 1.0 (07 version) is an updated product basing on previousMuse Deluxe 1.0. The outlook design, laser pick-up, servo system, andcontrol system of this new product is same as the ones for previousMuse Deluxe 1.0. The main improvement is on DAC sampling rate, analogyfilter and such aspects. The main characters for this new products areas follow,1.

Adopt 24Bit/192KHz upsampling technology, in order to improve the sound quality. The sampling rate is always a very important factor for sound qualityand also sound color. Higher precision, the analogy informationreplayed will be vivider and with more detail. Low sampling rate makesthe error after quantization is much more than the one of high samplingrate.

Those errors (quantization noise) make the sound tizzy and muddy,especially when the volume is low, such problem is very obvious. Thoseharmonic components cause additive distortion. Our engineers especiallydesign sampling rate process circuit for this new Muse Deluxe 1.0 (07Edition).

Such design could upsampling the rate as 24bit/192KHz fromprevious 44.1KHz/16bit, and also decode the CD digital signal record asPCM form after upsampling, in order to get higher process precision,improve the dynamic range and also the extension on the High, then thesound could be richer on the detail performance. 2.

DAC and analogy filterAD1852 is a DAC with 24Bit/192Hkz solution ability, which adoptsDelta-Sigma to decode. The new Muse Deluxe 1.0 (07 edition) adopts thisAD1852 for D/A converting the signal after sampling process. Therefore,it could replay every detail of the music precisely.

In addition, inorder to assure the precision of conversion, there is also preciseclock circuit, which could reduce the jitter and the distortion causedby that.

On the analog signal amplifier part, adopt OPA2134 and OPA134from Burr-Brown company, matching with lowpass filter, military graderesistor and high quality mica capacitor, in order to make the audiosignal purer. 3.

Power SupplyAdopt closed toroidal transformer, which with high flux and lessmagnetic leakage, matching with especial designed steel shield cover,to reduce the electromagnetic interference. In addition, the 70VAtransformer assures enough and steady energy supply to the circuit. 4.

Output PortsTwo groups of RCA output ports, adopt tube as buffer amplifier 6922 tube and elaborate design circuit, make the sound warm andsmooth. In addition, one group balanced output ports, make the sound stage performance wider and localization more precise.
