Rugged Build
Quality
Mechanical strength has been a hallmark of Perreaux products since th
e
company first started production back in 1974. The concept behind the physica
l
design and construction is that each structural member should contribute to bot
h
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 outpu
t
stage, another one for the DAC section, another for the clock generation of th
e
DAC section and a further supply for the microcontroller and display. Th
e
advantage of this is that there is complete isolation from stage to stage, ensurin
g
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 digita
l
to analog converter, featuring HDCD decoding. The dual 20-bit, multi-leve
l
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 tha
t
allows a CD to have greater dynamic range, focused 3D soundstage, reduce
d
distortion, and increased detail. When playing HDCD encoded discs, the ECD2
can reproduce as much as 20-bit dynamic range. HDCD discs are identified b
y
an HDCD logo on the package.
No user action is required to play an HDCD encoded disc. The playe
r
automatically senses HDCD encoding and enables the necessary circuitry. Th
e
HDCD indicator on the front panel will light to indicate that an HDCD disc is
being played.
