Perreaux Radiance R200i
Integrated Amplifier Review
by Robert van Waes
Hi-fi and music: it is a great hobby! Apart from all kinds of equipment
one also gets to meet many passionate people, every one of them with
their own view on audio reproduction. For example, I recently had the
pleasure to meet the owner annex business manager of High-end Chile,
Omar Gonzales and his charming wife Melanie (from Chile). This was a
very warm meeting indeed; those people became friends for life.
Another great thing was the new review candidate I picked up there, the
Omar was so incredibly convinced by this little body builder and its performance that he wanted
me to hear it in my own listening room, using my own set-up. Accompanied by some nice
Chilean presents the friendly importer for the Benelux, Electric Audio from the Dutch town of
Apeldoorn, gave me a Radiance 200i to review. Perreaux, housed in Mosgiel close to Otago’s
provincial capital Dunedin in southern New Zealand, was founded in 1974. Their first
commercial product was the GS2002 integrated amplifier, an amplifier that delivered an
amazing 22 Wrms per channel. In 1976 Perreaux produced New Zealand’s first ‘home-made’
PA system used by the locally famous rock band Ragnarok. The sound system weighed three
tons, delivered 900Wrms per channel and led to some world fame for the brand name
Perreaux since a few Australian export orders were placed as well. During the years 1977-1978
Perreaux discovered the MOSFET as an end transistor, an end transistor that combines the
sound advantages of tube amplification with the physical advantages of the classic bipolar
transistor amplification. In 1979 the first Perreaux MOSFET amplifier was released, leading to
the fact that the company kept on expanding during the eighties. Very remarkable is that,
according to Perreaux, despite thousands of units warranty claims have been virtually non-
existent in all of Perreaux’ history.

A USB-port allows for future software-updates to be carried out. Furthermore, one trigger input
and two trigger outputs allow you to switch a complete Perreaux set in or out of stand-by. An
IEC-power connector with built-in fuse holder allows the user to use a power cord as he
chooses and pleases. Because of the fact that the product is quite small the loudspeaker
clamps are rather close to the balanced in-clamps on the one side and to the IEC-power
connector on the other. It took some rearranging of my Kimber Select cables before the WBT
cable forks could be properly connected.
Inside
What strikes you inside is the purist way in which the dual mono construction of the R200i has
been carried out; one integrates as if it were two complete mono amplifiers into one casing
here. By applying two qualitatively high-power power circuits and strictly separated alignment
and flattening of the pre- and end-amplifier currents you get maximum channel separation.
Using six very high current Toshiba MOSFETs end transistors, a capacitor battery of 40.000
microfarad per channel and a maximum power capacity of 60 Ampere channel, the Radiance
200i can keep its head cool, no matter what loudspeaker is connected.
The low internal electrical resistance in conductor-state of the Toshiba MOSFETs takes care of
a lot less heat thus creating high thermal stability. Some top-class components made by
celebrated manufacturers such as Burr Brown and Crystal are used in the pre-amplifier section.
The microprocessor-controlled volume control is constructed around a double resistor-ladder
network built up of precision resistors. A remarkable characteristic in this price class! According
to Perreaux all of these aspects should guarantee an effortless reproduction of an extremely
stable and detailed soundstage with a maximum of dynamic contrasts.
All this musical violence is continually and accurately monitored by the (again) microprocessor-
controlled security circuit. External power supply, internal power supply, clipping, over-current
protection, over-temperature protection, current temperature of the end-stage, DC offset, etc…:
all of these are closely controlled by the microprocessor. In addition to all this, the security
circuit also takes care of the ‘soft start’ when switching the R200i on and off. You can access
the most important diagnostic data via the menu and see it on the display. Via this menu you
can even program a maximum volume setting: an extra certainty for the survival of your set
during teenage-parties taking place in your absence.
By themselves, numbers prove nothing. They do however say a lot about the components used,
and the care the manufacturer put in the construction of its product. Remarkable is that every
product is delivered with a bundle of measurement reports. The things promised in the
brochure are actually proven. The following specifications are quite extraordinary in the
integrated amplifier-class:

Let’s listen!
100 Kg Sushi power versus 13.5 Kg Kiwi power! My Sony E1-N1 pre-and end combination has
to make room for an opponent from New Zealand. The necessary cables are connected and
soon the first sounds enter the listening room.
What does this little body builder sound like? Often an amplifier has the tendency to tend to
either the ‘warm’ musical side, or the ‘cold’ analytical side. Only a few white ravens, for
example Spectral or the top of the digital amplifiers like the Lyngdorf Millennium, are blessed
with absolute neutrality, complete transparency and no trace of coloring in the entire frequency
spectrum whatsoever. The R200i can definitely join this elite! This member of the Perreaux
family seems to combine the best of both worlds in one compact casing. Not only is the R200i
very quick and open, it is also completely transparent and has natural, musical, light feet.

These characteristics, combined with absolute control and authority, make every listening
session a true pleasure. Perreaux has succeeded in a quasi-perfect symbiosis between two
audio components, namely speed and musicality. Grandiose, quick, powerful, authoritarian and
with an amount of control you would only expect from a heavy pre- and end combination, but
also equipped with speed, subtlety, refinement and compression less transparency. All this on
a level you would not expect from an integrated amplifier. The soundstage presented to us by
the R200i is open, wide and deep; you almost think there is 3D holographic reproduction
instead of a stereo system. Because of this almost entirely transparent character the amplifier
is very revealing, both towards the recordings and to the components around the amplifier. The
R200i hides nothing from and adds nothing to the real tonal color of the recording, source or
loudspeaker. The resolution of the reproduction is so high the instruments and voices become,
as if it were, physically touchable, they become completely disconnected from the soundstage.
Despite the very open, precise and detailed soundstage the reproduction never gets thin,
tenuous or fatiguing analytical.
The speed is presented to the listener in such a fluent way that I would sooner name the
reproduction to be absolutely neutral and musical, than I would name it purely analytical. An
aside: personally I think there is a great difference between a very detailed and a truly cold
analytical reproduction. A healthy dose of detail and transient reproduction give the musical
restitution just a bit more realism, whereas a purely analyzing product usually completely
destroys the coherence thus loosing a lot of musicality. The reproduction by the R200i is solid
as a rock and has a very natural presence. Another striking aspect is the formidable control
exercised by this giant over the loudspeakers. The double woofers of my Amati’s are kept firmly
in line by the R200i. Amplifiers that have no sufficient control are often responsible for a too
large amount of bass in our not-quite-finished (mostly where dampening is concerned) listening
room. However, this is not the case with this Radiance R200i, the dampening factor of more
than 2000 is clearly accountable for this. This results in a formidable bass control; not only is
the reproduction deep to the subsonic level, it is also tight, controlled and layered.
A wonderful recording to demonstrate this is the hybrid SACD “Far More Drums” by the Robert
Hohner Percussion Ensemble (DMP SACD-10). The stage is enormously wide and deep, a stage

that as if it were completely dissolves the speakers. On the field of ‘peace and rhythm’ the
R200i convinces again. The silences turn seamlessly into super fast, fierce and incredibly loud
attacks on the drums. Every touch is perfectly traceable with the tones slowly dying out as an
addition to the expression of the music. The wood percussion sounds pointy, accurate and
convincingly life-like. As a whole it is extremely convincing: quick, grand and pressure-full; but
very light as well. All the nuances in the bouquet of the different types of percussion are
depicted magnificently and create a swift, uncolored and no-compromise soundstage.
Assessment
Pros:
+ Build quality and finish
+ Top-class audiophile components and construction
+ No-compromise quick reproduction without any coloring
Cons:
– Perhaps the (for now) limited brand awareness in Belgium, as far as that is of any importance
to you
Conclusion
A perfect build quality combined with excellent design, components of the highest quality and a
tight, stylish design. Build-technically speaking this is a top product; this is (unfortunately?)
reflected in the price tag. The reproduction far exceeds the level of the average amplifier. In my
opinion the Radiance 200i deserves the tag “Reference” within the integrated amplifier
segment… and out of that segment as well! Strongly recommended!!
