At the mere mention of the TAG McLaren brand,
petrolheads and racing fans will sit up and take notice. And not
surprisingly, considering that the brand has been one of the most
successful in the cutting-edge world of Formula One racing.
Love or hate the team, the fans have never
begrudged McLaren boss Ron Dennis and his drivers their ability to
engineer exceptional racing machines. Indeed, one of the world's most
evocative road cars - and one of the rarest - once wore the McLaren badge
Underlining the spirit of technical
sophistication that is at the core of the company, TAG McLaren high-end
audio and AV components have been establishing themselves in the esoteric
category of one of the most competitive consumer industries in the world.
Also of interest is that TAG McLaren is very much
a British company, while it's been acknowledged that the majority of
high-enders have their origin in the United States.
That makes the AV32R Plus pre-amp/processor and
its partnering 100x5R five-channel power amplifier something of a home
theatre curiosity, and one that many seasoned audiophiles have approached
with a measure of scepticism.
Unless one is irrevocably biased in favour of US
marques, it doesn't take very long in the company of the TAG McLarens to
realise that, at the very least, these are classy and even unique AV
devices that deserve more than just incidental attention.
Let's start with the AV32R Plus - a slim and
deceptively simple-looking pre-amplifier/processor. This latest-generation
unit, not to be confused with the less sophisticated original, exudes the
kind of oiled precision and do-not-touch exclusivity that only paid-up
members of the esoteric audio club are able to muster.
Quite predictably, there is a lot more to the
AV32R Plus than initial impressions may suggest. In fact, it's teeming
with the kind of technology that could have qualified for science fiction
not that long ago.
The TAG McLaren processor is fully compatible
with all the current, conventional 5.1 surround sound formats: Dolby
Digital AC-3 and Digital Theatre Sound (DTS), as well as the original
Dolby Pro Logic and MPEG-2. It is also a fully THX Ultra-certified
But that's only the beginning of the AV32R Plus'
AV format repertoire. While some may not even have heard of the likes of
THX Surround EX 7.1, DTS ES 6.1 Matrix and ES 6.1 Discrete and DTS Neo:6,
these are all formats that make provision for more than the current 5.1
Effectively, it means that the AV32R Plus is as
future proof as they come. Not all the above formats will survive, but at
least this unit is compatible with all of them. And should new formats
appear - Dolby Pro Logic II is already being hailed as the latest great
development in home theatre - software uploads will ensure continued
It also underlines one of the cornerstone
philosophies behind the TAG McLaren - continuous upgradeability. For
instance, the AV32R can accommodate a second digital signal processing (DSP)
module, doubling processing power and associated quality standards.
Various upgrade boards allow further update paths.
Ensuring the continued relevance of the AV32R
through continuous upgrades is proof of TAG McLaren's attention to detail,
and its commitment to customer satisfaction.
That's also why the construction is top-notch,
with features such as gold-plated multi-layer PCBs, reference-quality
circuit components (including high-end video components), a toroidal power
transformer, and a vibration-resistant all-metal enclosure that
incorporates Sorbothane membrane-fitted feet.
The unit is also endowed with the latest in
technology. For instance, a proprietary T'L-link allows the AV32R and
other TAG components to synchronise their clocks to the AV32R's master
unit, allowing exceptionally low levels of digital noise and much reduced
A combination of surface-mounted digital and
hard-wired analogue audio circuit components is aimed at extracting and
maintaining optimum performance standards throughout the signal path.
Onboard D/A converters are true 96 kHz/24-bit
delta-sigma designs, while the top-end Analog Devices ADSP 2106SL SHARC
digital signal processor offers 32-bit, 66 MHz technology.
Analogue-to-digital conversion is via a 96 kHz/20-bit delta-sigma ADC with
Versatile connectivity is another TAG McLaren
AV32R Plus virtue, although the audio inputs and outputs are restricted to
single-ended RCA-type sockets. That's a pity, since the superior noise
rejection properties of at least some balanced input/output sets would
have certainly boosted appeal even further.
Video-wise, the choices are more varied, and
include both the preferred S-Video and the RCA-terminated composite video
options. Digital I/O sets offer both S/PDIF coaxial and Toslink EIAJ
optical options, with the former clearly the preferred choice.
The AV32R Plus comes with a full-featured TAG
McLaren system remote that's not only compatible with all the marque's
components, but can also be programmed to operate other AV components.
Other niceties include an upgrade module to allow automation functions
such as motorised curtain and screen control.
A natural power amplifier partner for the AV32R
Plus processor is TAG McLaren's own 100x5R multi-channel design.
Effectively five identical monoblocks sharing the same chassis, the
100x5R's design is completely modular to ensure future upgradeability.
A combination of short signal paths, high-quality
circuit components such as Vishay metal-film resistors and Wilma
polypropylene capacitors are typical of a circuit layout that also
features internal heatsinking and generous toroidal power supplies.
An onboard microprocessor controls the amplifier
by monitoring each channel for overloading or other faults, controlling
the start-up sequence, and allowing unused channels to be switched off,
such as when listening to stereo sources, for instance.
Fully remote controlled, the power amp is rated
at 100 watts RMS per channel into 8 ohms, can deliver up to 160 watts per
channel into 4 ohms, and even 190 watts into 2 ohms for short periods.
Signal-to-noise ratio is greater than 90 dB and THD comes to less than
The AV32R Plus and 100x5R were linked employing a
TAG McLaren Cinema Pack, which comprises five RCA-terminated analogue
interconnects, one for each channel. A TAG coaxial digital interlink
linked the Sony DVD player to the processor.
In line with its upmarket status, a set of
THX-certified M&K THX 150 home theatre speakers was used for this
review, accompanied by a M&K MX-350 active subwoofer. The whole system
was run to THX parameters.
For components that belong, as mentioned, in the
esoteric league, initial set-up is simpler than most, thanks to TAG
McLaren's belief that not too many users enjoy ploughing through
Instead, the AV32R employs an onboard, intuitive
set-up wizard - a set of step-by-step on-screen instructions that lead the
user through all the key set-up parameters. It's a very effective way to
get the system up and running, and means that the whole TAG McLaren set-up
was fully operational within half an hour of initial switch-on.
Vital though is that the S-Video output with
on-screen display is employed: the composite outputs offered as
alternatives don't carry OSD information. For those who do prefer manuals,
comprehensive literature is provided, however.
After all that, I'm sure your expectations
regarding actual performance of the TAG McLaren kit are as high as mine
were once the installation was complete. After some warm-up time, the
serious listening commenced - and I must admit that I wasn't disappointed.
The first impressions were of an articulate, open
and accessible sound that offered ample space for even the most complex of
soundtracks, together with an almost uncanny ability to extract and
project the tiniest particles of detail.
Indeed, it takes a system such as this one to
underline just how important these fine strands of information are in
providing the high levels of realism believable home theatre demands.
This detail was preserved in the broader context
of the expansive staging, rock-solid imaging and utterly credible channel
integration delivered by the TAG McLaren system.
It added the sonic cherry on top of a sound that
demanded attention, and remained compelling without any of the listener
fatigue that can so often spoil the sonic broth, especially when listening
to a system over extended periods.
If detail was impressive, then the sheer muscle
and control of the TAG McLaren kit was a wow, too. Frankly, the 100 watts
RMS per channel promised by the 100x5R looked just that little anaemic on
the spec sheet. But in reality, there was no shortage of oomph, even when
taxing sound effects were played back loudly.
Thrust and control were joined by arguably some
of the best Dolby Digital AC-3 and DTS decoding I've heard to date.
Channel-to-channel integration and exceptional directional steering
allowed a truly seamless rendition of the soundtrack, while the real
muscle of the power amplifier was obvious in the way it effortlessly
projected the kind of bass notes and effects that would have lesser
designs gasping for breath…
Clearly, the THX Ultra certification of the TAG
kit guarantees a certain minimum performance standard, but equally obvious
is that this system not only meets the requirements, but easily exceeds
The TAG McLaren AV32R Plus and the 100x5R power
amplifier are fine components that deserve to be considered in the
esoteric context. That goes not only for their design, construction
quality and ultimate performance, but also for their modular approach,
which allows simple extension of the basic building blocks into complex
Modularity also means that software upgrades and
hardware add-on boards have been catered for from the outset, ensuring
that the initial investment, although substantial, never has to go to
waste. Yes, this is top-end AV kit that those in the market for the best
should seriously consider.
