PHILIPS LHH300

Commentary

A CD player using the bit stream method.

The D/A conversion section adopts a bit stream method. In this method, the D/A conversion which used to use 16 circuit elements (resistors) is performed by a single switch circuit, making it possible to perform D/A conversion with high linearity without depending on the accuracy of elements.

The LHH300 uses a bit stream D/A converter in differential mode.
In differential mode, the left and right channels are fed to completely separate chips, and one chip receives the positive and negative phase components of one channel, and extracts the difference as an output to improve distortion, noise and channel separation.

A CDM-4 mini die-cast mechanism is adopted for the mechanism part.
This mechanism adopts a unique swing arm system with weights and balances placed at the rear, while further improving sound quality.

A die-cast chassis has been adopted for the chassis, eliminating the influence of external vibrations, etc.

The power transformer in the power supply section uses an independent winding method that separates digital, analog and servo systems.

Equipped with a large FIFO, it is possible to correct errors and jitter caused by scratches and external vibration when reading CDs.

Wireless remote control is included.
