MODEL5 INTEGRATED AMPLIFIER<br />
MAXIMUM PERFORMANCE FOR THE<br />
MONEY<br />
Avantgarde Acoustic, the highly respected manufacturer<br />
of exclusive spherical horn systems have<br />
ventured into the lion’s den and now offers for the<br />
first time a high end integrated amplifier within<br />
their product portfolio. A speaker specialist designing<br />
and manufacturing their own electronics? A<br />
closer look this new project shows a well thoughtout,<br />
coherent and most of all customer friendly<br />
concept.<br />
Horn loudspeakers are not only characterised by<br />
their extreme sensitivity and dynamics, but sometimes<br />
behave with all the agility of a flowering<br />
mimosa. It is true that due to their high impedance,<br />
the horn systems from Lautertal in Germany are<br />
very simple to drive. They simply represent an easy<br />
load for any amplifier, but their incredible resolution<br />
of fine detail quickly reveals the limits of many<br />
highly praised amplification. It is like in real life: for<br />
a good sound you have to combine what is a good<br />
match. An amplifier, which sounds great on a power<br />
demanding speaker system, will not necessarily be<br />
a good match with a horn. Like a big Diesel truck<br />
engine might be ideal to pull a 30-ton load, but in<br />
a racing car, it would certainly be the wrong choice.<br />
The classical virtues of any amplifier “all things to<br />
all men” attach great importance to – output power,<br />
Based on these considerations Avantgarde Acoustic<br />
has invested in a significant research and development<br />
program to realise a unique amplifier concept.<br />
The MODEL5 is a special integrated amplifier,<br />
which ideally matches their ultra dynamic speaker<br />
systems. With surprisingly simple means, the wellknown<br />
virtues of their horns – dynamics, resolution<br />
of fine detail and coherency are emphasized and<br />
brought to life. In this respect the horn specialist<br />
from Lautertal have made a courageous and most<br />
of all consequential step towards further perfecting<br />
their sound systems. Courageous because no other<br />
electronic manufacturer wanted to think about<br />
what’s really needed with the sensitive and revealing<br />
Avantgarde Hornspeakers. Consequential<br />
because a new benchmark in performance – and<br />
in affordability – is now available. Now the music<br />
lover can buy a perfectly balanced amplifier for<br />
their horn system – no “TRIAL & ERROR” when<br />
searching for the perfect sound combination, but<br />
simply “PLUG & PLAY”. “I admit it. We have purposely<br />
played the trump card of our high impedance<br />
and high sensitivity horns, because in combination<br />
with the MODEL5 we managed to achieve a<br />
sound quality at a price which is simply unbeatable<br />
when compared to normal speakers and amplifiers”<br />
states a very pleased Holger Fromme.<br />
In the following pages the special technical features<br />
of the Avantgarde Acoustic MODEL5 amplifier are<br />
explained.<br />
load stability, damping factor etc are of no circumstantial<br />
significance for a horn speaker system. With<br />
a horn, quality is simply more important than<br />
quantity. “I have never excepted that horn customers<br />
have to spend a lot of money for features, they<br />
actually do not need. It was our clear goal to concentrate<br />
on the essentials and design a simple but<br />
perfect amplifier for high sensitivity speakers. No<br />
unnecessary ballast like a big power supply or<br />
oversized transformers and numerous transistors.<br />
Maximum performance for the money!“ explains<br />
Holger Fromme, managing director of Avantgarde<br />

CLASS A MODE<br />
The MODEL5 is an integrated transistor push pull<br />
amplifier with a power output of 2 x 0.4 watts at<br />
8 ohm in pure CLASS A mode. At 20 ohms 1.1 watts<br />
is available in CLASS A before the amplifier converts<br />
to CLASS AB mode. Thus Avantgarde Acoustic<br />
consequently continiuous its high impedance technology<br />
with all its advantages first introduced in the<br />
TRIO OMEGA model.<br />
By increasing the bias current the CLASS A mode<br />
eliminates distortions when the signal passes the<br />
null point of the signal curve in push-pull ampli-
