The Red Reference and Red Standard

full sized CD players are truly unique.

These units offer superior technology

and audio performance when compared to

anything developed for CD replay so far.

Utilising the latest 64 bit DAC technology

and 4096 tap length digital noise shaping

filters and beautifully crafted machined

aluminium casework.

RED Reference

Building on the success of the Blu and the DAC64 the RED

Reference CD player has been designed as the ultimate source

component. With stunning looks and state of the art design the

RED utilises ground breaking technology to give the most

accurate reproduction of compact disc that can be obtained. With

internal 176.4KHz upsampling data transfer, selectable RAMbuffer clock retiming and both 1024 and 4096 tap length filtering

the RED earns its reference status in the Chord range.

RED Reference RED Standard

RED Standard

The RED Standard CD player combines

conventional CD playback with the addition

of DAC64 conversion technology to give

optimum performance at 44.1KHz sample

frequencies. It is able to reproduce

considerable clarity with the transient

timings accurately reproduced via the 64

bit DSP core and 1024 tap digital WTA filter.

SPM 1050 Power Amplifier

The SPM 1050 is the latest addition to our

range of stereo power amplifiers. Using the

latest low distortion amplifier circuitry with

our own proprietary lateral structure dual-die MOSFETs the SPM 1050 is able to drive

more difficult loudspeaker loads with clarity

and precision.

Chord Electronics Ltd is

pleased to introduce the

CPA 3000 as the next in the

range of our new generationof pre-amplifier products.

Using similar technology as

the highly successful CPA

5000 reference pre-amplifier

the CPA 3000 also features a

high frequency switch mode

power supply and ultra low

noise circuitry to give the

very best noise floor

CPM 2650 Integrated Amplifier

The Chord CPM 2650 integrated

amplifier is designed around the latest

versions of the highly successful

CPA2500 and SPM650 Pre and Power

amplifier combinations. It has all the

flexibility of its bigger brother, the

CPM 3350. Line level source selection

for up to six input signals can be

achieved using the supplied remote

handset or via the front panel controls.

Two tape loops allow you to record one

source whilst also listening to another.

A separate switchable preamplifier

output is available for bi-amping.

In tegrated Ampl i f ie r In tegrated Ampl i f ie r


The Chord CPM 3350 integrated amplifier

design is based on the CPA3200E and

SPM1050 pre and power amplifier

combinations but developed specifically to

give a one box solution. It offers all the

flexibility of a Chord preamplifier with linelevel source selection for up to six input

signals using the remote handset or via the

push button front panel controls. Individual

input gains can be selected to prevent large

changes in volume when switching between

inputs.Two tape loops allow for recording

one source whilst listening to another.

The power amplifier based on Chords tried

and tested technology of ultra high

frequency low ESR power supply has the

ability to store a great deal more energy,

and far more efficiently than conventional

designs.This gives the amp enormousreserves of instantly delivered, precisely

controlled power which is more than

capable of controlling even the most

demanding loudspeakers.

With the ability to select the pre outs and

speaker outputs together or individually the

flexibility of the unit allows it to be used as

a pre-amp, on its own or with another

power amp for bi-amping.

OurTechnology is some of the most advanced in the Audio Industry and stems from my earliest days as an Avionics Engineer

working on black boxes for aircraft. We were regularly given a space the size of a chickens wing at the back of these boxes in

which we had to shoe horn perhaps half a kilowatt of power. Invariably that meant we were pushing the limits of power supply

technology to complete the task. So with this knowledge base I was able to apply it to my hobby at that time of making

amplifiers for myself and friends. It occurred to me that effectively an amplifier is suspended between its power supply rails

there is a positive supply and a negative supply and a mid point, zero point known as ground.This reference point is at the back

of the amplifier and of course it tends to get pulled around when an amplifier is swinging between its rails.This would be no

problem but its the same reference for the front end of the amplifier so effectively if the loudspeaker is pulling on it, it

introduces a time lagged distortion component into the amplifiers input and this is one reason why amplifiers can burst into

oscillation, especially if you connect them to a highly capacitive load.The normal way of solving this is to make the front end

stages of the amplifier have a slower more sluggish response by the increasing the local feedback then opening up the loop

responses on the intermediate stages; this is the conventional way to keep an amplifier stable. I thought I could negate this

distortion component getting back into the amplifier and open up the responses by drawing power from both positive and

negative rails simultaneously at any time in the amplifiers output swing. I did this by using a cross coupled magnetic device

know as a bifilar wound choke which acts rather like a gyroscope. It likes to remain in balance with equal and opposite currents

flowing in both directions and when it sees a current demand from say the positive rail it automatically acts like a transformer

and pulls more current from the negative rail.The concept worked and I found I could open up the loop response throughout

the amplifier making it sound far more open whilst remaining completely stable.This concept has been enhanced and refined

over the last 30 years but remains the underlying principle of all Chord Electronics amplifiers.My collaboration with Robert Watts a digital design genius who spent the last 30 years developing DAC technology started in

1996. He had an ultra high performance design using filed programmable gate array technology and our breakthrough came

with chips that had an extremely high gate count. He designed a small card to drive a large pulse array switching ladder which

became the DAC64. There are few products in the world that can reach the performance of the DAC64 as most companies

producing commercial and industrial DACs use commercially available chips from Analog Devices or Burr Brown. Fabricated

from pieces of silicon around 3mm square they have structures fabricated at about 100 to 200 microns in size. Their arrays

contain the same technologies as ours but our pulse arrays are fabricated from discrete surface mount components and these

are physically 10,000 times larger and therefore we can maintain much greater accuracies and consequently significantly better

performance.

Our product styling comes from form following function. I draw my design influences from both aerospace and architecture. I

truly love great architecture. Greats such as Richard Rogers, Frank Lloyd Wright and even Antonio Gaudi whose quirky joy

bursts from every building hes ever designed. It may be someday you may see a Gaudi inspired design from Chord, but thats

for another year.
