CD-S2000 Discontinuo
Full Floating and Balanced Circuit Design Achieves for the First Time the Full Potential of Analogue Amplification
More than forty years have passed since the introduction and widespread adoption of full transistor HiFi audio amps during the 1960s. In the 1970s, high performance, high output PNP-NPN transistors made possible the pure complementary configured power amps that are now the main type of high quality audio amps. In recent years, however, digital amps have become popular for their high conversion efficiency and superior uniformity of operating precision, as well as for their lower weight, size and heat production as compared to analogue amps. Which leads to the question, which direction will audiophile-level amps take in the future? Generally, two possibilities are considered: continuing to improve the traditional pure complementary configuration analogue amps or working to achieve higher sound quality from digital amps. But Yamaha has selected a third approach. This is an entirely new floating and balanced power amp that, by using power transistors with the same polarity that are not complementary, achieves complete symmetry of pullable operation at the output stage and permits full balanced transmission (amplification) from the input jack to just before the speaker jack — a capability that has long been the dream of audiophiles.
Trasmissione bilanciata del segnale dal convertitore D/A
In the quarter century since the CD medium appeared, it has become widely popular for its combination of excellent quality and convenience. CDs can now be played on DVD players as well, but for the highest reproduction quality, a dedicated CD player should be used. Yamaha recognised the need for a CD player that would allow audiophiles to enjoy their music exactly as it was recorded, with absolutely nothing added or lost.
In order to realize ideally balanced signal transmission when this player is connected to the A-S2000 integrated amp, the D/A converter uses a differential motion mode to achieve balanced transmission of all stages after it. Music fans can realise the audiophiles’ dream of fully balanced signal transmission from DAC output to just before the speaker jack by pairing this machine with the A-S2000.
Full-Stage Balanced Signal Transmission Beginning with the DAC
The CD-S2000 features a differential motion D/A converter that succeeds in doubling the conversion precision by using Yamaha’s high precision DAC converters on the plus side and the minus side. The outputs of the plus and minus sides are input into isolated low pass filters, and transmitted in a fully balanced state from there to the output jack. Combining this player with the A-S2000 amplifier lets you enjoy high purity CD reproduction of a quality unmatched in this class, thanks to an absence of transmission noise and related sound degradation.
Caricatore silenzioso e con unità CD ad alta precisione
The mechanism that picks up the signal is actually analogue, even during the digital reproduction of a CD. So the quality of the precision of the drive mechanism has a significant impact on the precision of the subsequent digital signal, and on the final sound. The CD-S2000 uses the Exclusive Yamaha Loading Mechanism with Superior Quietness that solidly supports the CD drive, and a highly reliable brushless spindle motor. The aluminium disc tray provides a luxurious touch matched to the superb sound quality.
Trasformatore con sezioni isolate per segnali digitali, analogici, del motore e di visualizzazione per evitare interferenze
The independent power supplies use separate transformers to isolate the audio circuitry from the digital circuitry to eliminate any effect of noise from both circuits. The audio section employs a toroidal transformer that holds down magnetic flux leakage to achieve a stable power supply. Specialised windings on the left and right channels isolate the rated current circuits to the left and right beyond them, achieving superior separation characteristics.
Pure Direct per un percorso segnali breve e diretto
This is the first Yamaha CD player to incorporate the Pure Direct circuit, which has long been provided on our AV amplifiers.
Since this player has separate analogue and digital sections, the same as an AV amp, we decided that using AV amp expertise was a good way to achieve high sound quality. When Pure Direct is on, the display is turned off and digital output is stopped, realising the highest possible analogue sound quality.
Struttura
Like the A-S2000 integrated amp, the CD-S2000 has a left-right symmetrical design with rigid, stable construction due to a reinforcing bar in its centre. Specially designed feet stabilize the grounding and are very effective in damping external vibrations.
Suono super da CD Super Audio
The CD-S2000 is capable of playing Super Audio CDs, for an even more dynamic listening experience.
Choise of Two Bases
The extra-heavy feet provide a choice of two bases. You can leave the round, flat neodymium magnets in place or remove them to rest the amplifier on four single points. The feet are also height adjustable. They ensure stability on any surface, with superior vibration damping.
