■The D-M33 inherits Denon technology from high-end models to faithfully reproduce the original sound.
Capacitors developed for high-quality audio have been used in the circuitry of the power amp that determines sound quality and in the D/A converter section that converts the digital signal from the CD into an analog signal. In addition, the D-M33's high-class separate components feature Burr-Brown D/A converters from Texas Instruments Inc. that are well known for their superior sonic performance. The converters faithfully preserve both the powerful dynamics and the delicate nuances of sound as they convert the CD's digital signals into analog form for the speakers.
■MP3 and WMA playback
In addition to CD and radio sound sources, the D-M33 also plays MP3 and WMA files recorded on CD-R or CD-RW media. To play these discs, simply load it and push the Play button. You can also select a folder on the disc and just play the files in that folder. When a file is played, the artist name, song title, track number, album name and other information is displayed. Repeat or Random playback is also possible.

■Hi-Fi Speaker system with the New European Tuning
The SC-M53 is a speaker system with high sound quality that has been newly tuned for the RCD-M33. The bass driver has an inverted-profile double layer cone. This one-piece design does not use a centre-cap and therefore provides greater rigidity across the surface of the bass cone.
•Newly-developed drive unit
As shown in figure 1, the driver uses an inverted-profile double layer cone. Detailed “finite element analysis” was used to find the optimum thickness on each part of the subcone and the best connection point between main cone and voice coil. This design controls the break-up modes of the cone for a more stable sound. Figure 2 shows an analysis of the woofer diaphragm at 1.4 kHz. Piston motion is uniform over the entire diaphragm even at this frequency which is high for a woofer. In addition, the secondary cone has not been bonded to the edge of the driver in order to optimize control over vibration to the outer perimeter. This design thoroughly minimizes influences on the secondary cone that actually emits the sound.
•Speaker cabinet
The speaker cabinet is constructed with MDF material. The acoustic design of the cabinet was optimized through laser scan measurements of vibration in the cabinet. The cabinet also features a white wood grain finish that is often used in northern European furniture. Careful attention has been given to the rear of the speakers as well, where higher quality 5-way binding terminals are featured.
•Network
An acoustic fourth order LCR filter has been used for the network to obtain opti- mum phase matching between the woofer and tweeter.
