Welcome.
We are delighted that you have decided to purchase a product. With your new MP 2500 R you have acquired a
top-quality piece of equipment which has been designed and developed with the wishes of the audiophile music lover as
absolute top priority.
This system represents our very best efforts at designing practical electronic equipment incorporating solid quality, user-
friendly operation and a specification and performance which leaves nothing to be desired.
All these factors contribute to a piece of equipment which will satisfy your highest demands and your most searching
requirements for a period of many years. All the components we use meet the German and European safety norms and
standards which are currently valid. All the materials we use are subject to painstaking quality monitoring.
At all stages of production we avoid the use of substances which are environmentally unsound or potentially hazardous
to health, such as chlorine-based cleaning agents and CFCs.
We also aim to avoid the use of plastics in general, and PVC in particular, in the design of our products. Instead we rely
upon metals and other non-hazardous materials; metal components are ideal for recycling, and also provide effective
electrical screening.
Our robust all-metal cases exclude any possibility of external sources of interference affecting the quality of
reproduction. From the opposite point of view our products’ electro-magnetic radiation (electro-smog) is reduced to an
absolute minimum by the outstandingly effective screening provided by the metal case.
We would like to take this opportunity to thank you for the faith you have shown in our company by purchasing this pro-
duct, and wish you many hours of enjoyment and sheer listening pleasure with your MP 2500 R.

Introduction
PCM and DSD
Two competing formats are available in the form of PCM and DSD, both of
which are used to store audio signals at very high resolution and quality. Each
of these formats has its own specific advantages. A vast amount has been
written about the relative merits of these two formats, and we have no intention
of participating in the dispute, much of which is less than objective in nature.
Instead we consider it our task to develop equipment which reproduces both
formats as effectively as possible, and exploits the strengths of each system to
the full.
Our many years of experience with both systems have clearly shown that PCM
and DSD cannot just be lumped together; it is essential to treat each format
separately, and take their specific requirements into account. This applies both
at the digital and analogue level.
For this reason the MP 2500 R employs two separate digital sections and two
D/A converter sections - each optimised for one format.
MP 2500 R and DSD
By its nature the DSD format involves a noise floor which rises above the range
of human hearing as frequency rises. Although this noise floor is not directly
audible, it does subject the treble units in the loudspeakers to a significant
load. It is also possible for the high-frequency noise to cause distortion in many
low-bandwidth amplifiers.
The lower the DSD sampling rate, the more severe the inherent noise, and it
cannot be disregarded, especially with the DSD64 format - as used on the
SACD. As the DSD sampling rate rises, the high-frequency noise becomes
increasingly insignificant, and with DSD256 it is virtually irrelevant. In the past it
has been standard practice to apply digital and analogue filtering processes in
an attempt to reduce DSD noise, but such solutions are never entirely without
side-effects on sound quality. For the MP 2500 R we have developed two
special techniques designed to eliminate the sonic disadvantages:
1.) The True-DSD technique, consisting of a direct digital signal path
without filtering and noise-shaping, plus our True 1-bit DSD D/A converter
2.) Analogue reconstruction filter with automatic bandwidth selection.
MP 2500 R and PCM
The PCM process makes extremely high-resolution sampling values available:
up to 32 bits. However, the sampling rate of PCM is significantly lower than that
of DSD, and the spacing in terms of time between the sampling values is
greater.
This means that it is extremely important with PCM to employ maximum
possible precision when converting the high resolution into analogue signals.
Here at our answer was to develop quadruple D/A converters which
provide a four-fold improvement in accuracy over conventional converters. A
further very important aspect of PCM reproduction is to reconstruct the curve of
the original analogue signal between the sampling points with great accuracy,
since these points are much more widely spaced in comparison with DSD. To
this end the MP 2500 R employs a polynomial interpolation process (Bezier-
Spline interpolation) developed in-house at , which in mathematical terms
delivers the smoothest curve for a given number of reference points (sampling
points). The output signal generated by Bezier interpolation exhibits a very
“natural” shape, devoid of the digital artefacts - such as pre- and post-
oscillation - which are usually produced by the standard oversampling process.
More detailed information on this can be found in the chapter “Technical
description, oversampling / up-sampling”

Front panel controls
All the important functions of the MP 2500 R can be controlled using the buttons and the rotary knob on the front panel.
Direct-acting buttons are provided for fundamental functions such as source select. Functions which are needed less
frequently are controlled using a menu which is called up by pressing the button.
All information relating to the machine’s state are displayed on the integral screen. The following section explains the
functions of the buttons on the machine, and the information provided on the screen.
 On / Off switch

A brief press on the button switches the unit on and off.


In Comfort Standby mode the button of the MP 2500 R glows dimly to
indicate its state of readiness. In Eco Standby mode the button is not
lit. (see chapter ‘Basic settings of the MP 2500 R')

Caution!
The mains button is not an isolation switch. Certain parts of the machine
remain connected to mains voltage even when the screen is switched off and
dark. To disconnect the device completely from mains power supply, the mains
plug must be withdrawn from the wall socket.
If you know you will not be using the machine for a long period, we recommend
that you disconnect it from the mains
 Source selection
  SRC
Pressing one of these buttons selects the desired listening source. Press one
of these buttons repeatedly if neccessary until the desired listening source
appears on the screen.
 CD drawer
The drawer is opened and closed by pressing the button.
If you press the / button after placing the CD in the machine,
the drawer closes and playback starts with the first track.
The open drawer also closes if you enter the number of a track using the
remote control handset.
