What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Alchemist Nexus APD32A CD player

24-Bit CD Player

The new APD32A Nexus 24-bit CD player now utilises the very latest available technology in the form of the latest Crystal CS4334, 24-bit 96 kHz surface mount DAC chip and CS8414 96 kHz receiver chip.

The APD32A Nexus CD players has been redesigned to perfectly match the Nexus range of amplifiers. As with all our products it is first and foremost a musical performer, although the visual appearance of our products is of a truly high standard.

The Nexus CD also offers the facility of a digital output. This can be used to connect the Nexus CD to another external DAC that will further improve the performance, maybe this woukd be the Alchemist TS-D-1 24/96 kHz DAC

 

The APD32A Nexus CD player has been redesigned to fulfill the requirements of our markets to have a fully matching unit to the APD32A and offer the latest in modern day technology. The evolution of the Nexus 24-Bit CD offers a significant improvement on the original design.

-The DAC performance has been up-rated to allow the playback of the very latest 24-bit software. This is achieved using the very latest in surface mount technology, which includes the new Crystal CS4334 24/96 DAC and CS8414 96 kHz receiver combination

The transposrt has been based around the very latest in ECO modules from Philips. This module will facilitate the playback of CDR-W, enabling you to play back your own compilations.

-High Capacity, low flux, toroidal transformers improve imaging and give greater stability to the sound stage.

Additional circuitry for EMC filtering has been implemented in a unique way to improve sound quality.

The new styled casework offers a more modern approach whilist still maintaining Alchemist undoubted originality

The fully regulated power supplies for all sections of the tha DAC have been retained.

Also retained is the feature of using two mains transformers. One exclusively for the digital domain the other for the analogue electronics.

High quality plated push buttons control all the players functions and offer a very high level of aesthetic appeal.
