Entry level, mid-fi and suggestions to my friends.
It's
often happened, and still happens to me, that some younger
colleague or some friend of mine who is just beginning to
look into the hi-fi world, require my advice on how to enter
the exciting and somehow chaotic domain of correct audio reproduction.
During the years when stereo reproduction was predominant,
HT was far beyond horizon, my answer was quite simple (if
we consider it "simple" to suggest anything related
to your own personal emotion); I just had to mention a few
names at a certain price level and suggest them to have a
listening session.
Now the things have changed: HT is among us, and with that
the low-cost dedicated integrated amp/tuner (with exceptional
power, DSP effects, an FM radio tuner), so I am also forced
to explain why, for the same money, it is more advisable to
buy a two-channel amplifier.
Today the range of 2 CH stereo amp is increasing its average
quality level on one hand, while on the other hand is also
shrinking in products number (fortunately the range is still
wide enough) thus making the choice harder.
It seems to me that a large part of the Japanese manufacturers
(except for a few names like Marantz) is leaving this specific
market.
Actually the choice in this field is mostly made between UK,
Italian (the number of Italian products is increasing, as
is the sound quality) and, in a not too distant future, even
Chinese products.
I have to admit that lately the British-made amplifiers, except
for some classic names like NAD and Rotel, which are only
designed in GB, don't have a good share in the Italian market
because of the unfavorable EUR/GBP rate, of a somewhat shy
marketing strategy and also because of the increasing success
of the Italian production.
The product I am going to test is the ARCAM A65 Plus, an entry-level
amplifier of the British company that completely fits in the
description above.
ARCAM
The
name ARCAM is part of the British hi-fi history. The company
started in 1972 and its first important amplifier, named A60,
has been issued in 1976. Arcam, or what their name was then,
had thought only 50 A60 were to be made, but the amp became
a bestseller item with more than 30,000 pieces sold.
A great part of the success of the name ARCAM in Italy is
due to the Alpha range CD players (that range is the foundation
of these newer designs). The company has restructured its
catalogue, also in consideration of their entrance in the
A/V arena. The amplifier we will test is in fact part of the
new DIVA range (Digital Integrated Video & Audio) which
is organized as follows:
3 integrated amplifiers (A85, A75, A65); 4 CDPs (CD62, CD72,
CD82 and CD92); 2 power amplifiers (P85 and P75); 3 tuners
(T51, T61 and DT81 with DAB). The HT products are 2 DVD players
(DV88 plus and DV89 which incorporates DVD-audio technology);
and 2 A/V amplifiers (AVR100 and AVR200). A wide catalogue
offer that tries to fill all the new audio/video reproduction
needs.
DIVA
with a new dress
I
must confess: I have never found the look of the Alpha range
that exciting. That was not because of its design but only
because of that plastic-ish feeling given by the front panels.
Now ARCAM uses a more conventional design (see picture) with
the opportunity to choose between black and grey colour (which
is the one I like most): the latter makes the A65 look like
the new Rotel RA01 and RA02.
The use of an aluminium front panel which all the various
control knobs come out from, through black-contoured holes,
is especially effective: it is not a revolutionary design
concept but it is extremely nice.
All the controls are horizontally aligned; the knobs have
three different diameters depending on their function: large
for volume, medium for balance and input selector, small for
switches. Even if there are a lot of controls, the front panel
still looks clean and nice. From left to right we find: the
IR receiver for the included remote control unit; the input
selector with 5 small LEDs to indicate the selected source
(4 line in and 1 phono MM); the motorized volume potentiometer;
the "direct" switch to by-pass the tone and balance
circuitry; the SP2 switch to commute the output to a second
pair of loudspeakers; the headphone jack socket, the ON/OFF
button with a bicoloured LED (orange at start, green when
ready).
The feeling you get using these controls is very good even
if they don't seem so solid and precise. Slight problem: from
a certain distance you cannot make out any more the tag of
the volume knob that gives its exact position.
No surprises even on the rear panel. We are pleased to find
an IEC mains socket, that allows using other power cords than
the one included in the A65 package. In the center are placed
the speakers connectors (4 + 4 for the two pair) while at
the right end there are the four "line" and the
single "phono" input sets. Just at the right of
the phono input there is a small hole to gain access to a
switch that turns the "phono" input into a standard
"line" one, in case no turntable is connected. Then
we find the rec IN/OUT and the pre output. Finally a "Made
in Great Britain" tag guarantees the origin of this amplifier.

The supplied remote control is just a middle class unit, perhaps
not even good enough for an entry-level gear. From the operating
instruction manual we learn that the other amplifiers come
with a better-designed device.
The
heart of the A65, TORX screwdriver at hand
Let's
undress this amplifier and have a look at the inside: the
first thing I see is how the factory managed to allow the
choice between black and grey . The alu case is the same for
both versions. It also keeps a direct mechanical connection
with the front commands, so that it's enough to mount the
front panel of the chosen colour with its matching alu cover
to get the customisation done: these are the sole two differences.
Four rubber pads support the whole cabinet.

The inside of the cabinet is completely filled by a large
printed circuit board: at a first glance we notice the absence
of any SMD (surface mount) component and the large number
of discrete ones. The power supply section, installed at the
right side of the same PCB, shows a toroidal transformer that,
consistently to the British tradition, is quite beefy. We
also remark the presence of two 10.000µF filter capacitors
by Rubycon.

On
the far left, close to the phono input, lays the RIAA stage.
This circuit is based upon an operational amplifier and, apart
from the excellent capacitors, does not seem to be so complex
(later on we will discover how it sounds). The overall assembly
of the amp reveals that the design was conceived with build
quality and audio performance in mind. This is quite evident
if we give a look to the Omron power relay whose function
is to protect the loudspeaker outputs: two small pieces of
damping matter have been added most likely to reduce undesired
vibrations.

The
volume potentiometer is an motorized ALPS

while
all the other potentiometers and selectors seem to be of a
slightly lower quality. Anyway, generally speaking we may
say that onboard components quality is very good. The only
thing that causes some initial perplexity is the scarce radiating
surface of the cooling fins, which the two power stages are
secured to

A deeper look at the assembly shows that those small, black,
extruded fins are part of the whole alu cabinet that will
ease heath dispersion thanks to its wider surface
Let's
turn it on
The
A65 plus I've tested here was a brand new piece, that had
just left its production line. All its components were sealed
for protection therefore some run-in was necessary.
The operating manual is a good one.
The software I used during the test is the following:
CDs
Annie Sofie von Otter & Elvis Costello "For the stars"
DG
Jacques Loussier Trio "Play Bach" PAPAGENO
Minnesota Orchestra, Mussorgsky/Ravel "Pictures at an
Exhibition" RR
A. Forcione "Ghetto Paradise" Naim
LPs
A.Forcione - S. Sciubba "Meet me in London" Naim
Roxy Music "Avalon" Polygram
Tracy Chapman "Tracy Chapman" Elektra
The
system was:
Analogue sources: Pro-ject 6.1/Grado red; Thorens TD160/Adcom
high output level MC
Digital source: Marantz CD 63 KIS
Amp set: Cyrus 3 + PSX power supply unit
Speakers: Monitor Audio studio 3 (a 90dB tower speaker)
Signal cables: VDH Hybrid MK2, YBA Crystal
Power cables: YBA Glass
As
you can see the Arcam A65 will take the place of another British
component that, when fed by its power supply booster unit,
delivers a 50W output. The A65 goes only up to 40W. Therefore,
if 50 Watts are required, the correct choice is its larger
brother A75.
Like for any other test, I had my usual set of vinyl and CD
records ready. When the test was nearly over I realized that
a record-by-record listening report would miss the point.
For this reason, since my impressions were consistent along
the whole test, I decided to write down a general evaluation
only.
Let's start talking about the phono input. I have previously
described its circuitry as very simple but its sound reveals
that this is an excellent phono stage, at the same level of
the one installed in my Cyrus.
The other thing I learnt is that this amplifier plays very
well from the earliest switch-on. Only a more accurate listening
session will reveal some minor sound improvements after many
days of testing.
Sound
The
impact I had from the little ARCAM was nearly astonishing:
the sound coming out the Monitor Audio was incredible in micro-dynamics;
instruments are airy and well outlined. Even in the most difficult
parts, it was easy to follow each score; the upper midrange
truly excels, even if this means that the stage is, sometimes,
a bit forward.
Voices are big, beautiful and present; the lower range is
well extended and with high-efficiency speakers you can get
a good dynamic impact too. I believe that the only thing you
should care about, when buying this amplifier, is to choose
loudspeakers with a 90-dB efficiency at least (in this sense
the match with the Studio 3A was outstanding).
Evaluating the transient response, I think that the designers
tried to optimise the pulse response rather than continuous
one; this gives advantage to the guitar arpeggios, the piano
and the drums.
Of course any choice has two faces: I've already discussed
the pros, while the con is that the power at hand cannot guarantee
long-term performances with high output signals. In this specific
situation the Cyrus 3 is an unstoppable bulldozer. To be noticed
that the ARCAM shows a relevant cabinet heating just after
half an hour of normal listening. As I've already pointed
out, this is part of the design but, in my opinion, it might
be a little bit too much.
If this amp is coupled with efficient speakers and there is
no need for long-term high power output, the sound you can
get is surely satisfactory.
Conclusions: the Cyrus' greatest advantage is a powerful and
controlled bass, while the main feature of the ARCAM is an
excellent micro-dynamic. On upper midrange the field is level.
This ARCAM A65 plus is a great amplifier and, if you pay attention
to connect to it speakers with an approx 90dB efficiency,
it is an absolute good choice.
