Peachtree Audio iDecco

World’s 1st Tube Hybrid Integrated
Amp with PURE DIGITAL iPod Dock

The Peachtree Audio iDecco extracts the digital audio from your iPod and sends it directly to the iDecco's built-in high-performance ESS
Sabre DAC. After the digital bitstream is converted to an analog music signal,
it travels through the iDecco's class A tube-buffered preamplifier stage to a
high-current, 40 watt per channel amplifier, ready to drive your speakers of
choice.

The iDecco is actually FIVE products in one . . .

• PURE DIGITAL iPod Dock


• Integrated Amplifier


• Class A Tube Preamplifier


• Stand-Alone Multi-Input DAC


• Class A Headphone Amplifier

In addition, the iDecco provides a component video out
connection so you can use your iPod as a “New Millennium VCR” and watch movies,
TV shows and podcasts on your flat panel TV or monitor.

The Perfect Desktop Audio Solution

If you sit at your desk listening to plastic speakers
for long periods of time, the iDecco will transform your work space into
high-end audio heaven. Just plug your computer into the iDecco with a USB cable
and use a matching pair of Peachtree Audio speakers. We’ll make you fall in
love with your work space!

PURE DIGITAL iPod Dock

Most iPod docks have analog outputs, forcing you to use the iPod’s internal power supply, DAC
and output section. Not so with the iDecco. We send the PURE DIGITAL "1’s
& 0’s" from your iPod directly to our Super DAC - so for the first
time your iPod can really perform like a high-end CD player.

The DAC

The heart of the iDecco - and what takes the iPod and
your other digital sources to a new performance level - is its outstanding
digital-to-analog converter. This DAC is the result of two years in development
and many hours of critical listening. We employ the ESS 9006 Sabre DAC for
digital processing. Our design uses a multi-layer DAC board with over 450
components and 11 regulated power supplies.

Harsh Environment

The ESS Sabre DAC’s patented jitter reduction circuit
re-clocks the digital signal before passing it through a high-resolution
24bit/96kHz upsampling processor. This is perfect for computers and most
streaming or hard-drive based music servers because most of them have high
levels of jitter. Jitter, simply put, is digital timing error between the
source and the DAC. The lower the jitter, the better the DAC sounds. Our DAC
takes the re-clocked signal and upsamples it to achieve 24/96 resolution. This
transforms your iPod or just about any digital source to the performance of a
high-end CD player. Even cheap transports and high jitter sources like
computers and iPods now sound great because the iDecco thinks they're all
high-end digital transports! The iDecco can deliver an astounding 118 dB signal
to noise ratio, greatly extending dynamic range and your overall music
experience with virtually all digital sources.

Each digital input is transformer-coupled so noise
associated with ground problems and switching power supplies from computers is
eliminated. The USB connection is galvanically isolated, eliminating noise
generated by your computer’s switching power supply and greatly improving sound
quality.

The Preamp

The iDecco's preamplifier section employs a class A
tube buffer with a 30 ohm output impedance - so if 40 watts per channel isn’t
quite enough power, you can hook up a separate, more powerful amplifier. The
preamp maintains a high level of detail while also taming harsh, compressed
digital music. The iDecco has a USB input for your computer, plus 1 coax and 1
optical input for other digital sources like Squeezebox, Apple TV or Airport
Express, Sonos, and XM or Sirius tuners. It also has 1 analog input for a tape
deck or phono preamp. iDecco covers the bases!

Quiet!

For the headphone user the iDecco has a class A tube
headphone section that rivals some of the best headphone amps available today.
When headphones are plugged in, your speakers are muted so you can rock on when
quiet is a necessity. Headphones have never sounded better than through the
iDecco!
