Special Design Features
Rugged Build
Quality
Mechanical strength has been a hallmark of Perreaux products since the
company first started production back in 1974. The concept behind the physical
design and construction is that each structural member should contribute to both
rigidity and performance.
Multiple
Regulated
Power
Supplies
There is a separate regulated power supply for each section of the CD player.
One positive supply and one negative supply for the sensitive analog output
stage, another one for the DAC section, another for the clock generation of the
DAC section and a further supply for the microcontroller and display. The
advantage of this is that there is complete isolation from stage to stage, ensuring
the analog section is completely free from digital noise.
Dual 20-bit
Burr Brown
DAC
The ECD2’s precision transport is backed up by Burr Brown’s PCM1732 digital
to analog converter, featuring HDCD decoding. The dual 20-bit, multi-level
Delta-Sigma operation with 8x oversampling ensures the ECD2 will deliver a
high level of audio performance.
HDCD ®
Decoding
High Definition Compatible Digital™ (HDCD ® ) is an encoding technique that
allows a CD to have greater dynamic range, focused 3D soundstage, reduced
distortion, and increased detail. When playing HDCD encoded discs, the ECD2
can reproduce as much as 20-bit dynamic range. HDCD discs are identified by
an HDCD logo on the package.
No user action is required to play an HDCD encoded disc. The player
automatically senses HDCD encoding and enables the necessary circuitry. The
HDCD indicator on the front panel will light to indicate that an HDCD disc is
being played.
