New DVD-Audio music releases and talk about the latest players.

I'm not a techie so I'm not sure if this holds any specific promise:

Manufacturers of DVD-Audio and SACD players may enjoy using the new multi-channel Cirrus Logic CS4382 8-channel digital-to-analog (D/A) chip. This new chip also performs digital interpolation, fifth-order Delta-Sigma D/A conversion, digital de-emphasis, volume control, and analog filtering. According to Cirrus "The advantages of this architecture include ideal differential linearity; no distortion mechanisms due to resistor matching errors; no linearity drift over time and temperature; and a high tolerance to clock jitter." The CS4382 accepts PCM (pulse code modulation) data at sample rates from 4kHz to 192kHz (for CD and DVD-Audio) while it also handles Direct Stream Digital (DSD, for Sony's proprietary SACD format). Features of this new chip include:
* 24-bit conversion
* Up to 192kHz sample rates
* 114dB dynamic range
* -100dB THD+N
* Supports PCM and DSD data formats
* Selectable digital filters
* Volume control with soft ramp
* 1dB step size
* Zero crossing click-free transitions
* Dedicated DSD inputs
* Low clock-jitter sensitivity
* Simultaneous support for two synchronous sample rates for DVD-Audio
* Microcontroller or standalone operation
