| CONCOURS D’ELEGANCE OF INTEGRATED
AMPS: SHOWCASING THE MBL 7008 AND THE
CHALLENGER, MARK LEVINSON 383 INTEGRATED
AMP |
|
May 2005 |

Recently, I had the privilege of
spending some time tinkering with and
listening to MBL’s newest integrated amp, the
Model 7008, to see how it compared to the top
contender in this field, the Mark Levinson 383
integrated amp. Before I go any further, let
me make two observations: First, it is always
a delight for me to spend with audiophiles
talking about the mutual love they share for
music and cars. There is just something about
the first Porsche Carrera RS model that had a
rear spoiler extending into the top of its
rear fenders, and the form-follows-function of
a gleaming Levinson 383 integrated amp that
brings men and (hopefully more) women to the
pursuit of this love of ours: getting closer
to musical truth and the intention of the
artist in the recorded music we love. Second,
let me state for the record that I realize
very few of us in these tough economic times
can actually afford to purchase either of
these pricey integrated amps. However, I
venture to argue that just like the new
Porsches we see on the track (which few of us
can afford to own), these top of the line
audio products inform the industry what to
strive for, in sonic excellence, new
engineering techniques and craft design. This
is a good thing, especially when such
technology and craft are incorporated into
more affordable gear that many of us can
afford to purchase.

The Hood

Similar to the improvements rendered
by a new K-Jetronic fuel injection system, a
two-way catalytic converter and an air
injection pump, all found on the 1978 Porsche
911 SC model, (as opposed to its predecessor,
the 1975-1978 911), a look under the hood of
the MBL 7008 and finds an array of German
engineering improvements aimed at MBL’s goal
of providing a shorter signal path for purer
musical reproduction. In the power section,
the 7008 is designed with dual-mono
construction, using two separate power boards.
Uniquely, the heat sink is on the top of the
unit, which MBL claims creates the shortest
signal path and most homogenous temperature
field for lowest thermal distortion. Rated at
120W into 8 ohms (200W into 4 ohms), the 7008
never broke a sweat at even the most
challenging decibels driving various
loudspeakers with impedances of 5 ohms and
under (Ascendo System F-3; MBL 311E), and
those with relatively low sensitivity below
86dB/1W/1m (MBL 311E; Harbeth Super HL5). No
trailing throttle oversteers, no front-end
shake, (like the classic 911 cars) just pure
agility and seemingly unlimited power from
this power section.
The 7008’s preamplifier section is pure analog
from the input (over a precise volume control
potentiometer) to the output stage, with the
power supply for the preamp input stages
located on the same circuit board so as to
insure a short path to supply the input
circuits. There is also a separate transformer
for low power analog input electronics
directly on the input circuit board, again to
insure separation of high and low current
transformers. Adding dimensionality is the
ability to use the 7008 as a stand-alone
preamp, or in conjunction with a surround
processor, utilizing its unique
processor/bypass feature. Around back, the MBL
sports gold plated XLR sockets, fairly decent
quality RCA jacks and speaker binding posts,
an input for an optional phono stage and a
removable power cord. The adjustable digital
display is relatively small in size, and can
be difficult to read from a distance. My chief
complaint is with the remote, made of plastic
with buttons set too close together. For a
vehicle of such price and distinction as the
7008, the remote should be of better build
quality and ergonomics. Contrasted to the
remote, the entire build quality of the 7008
chassis is first rate, with clean sleek lines
and no sharp edges to its heat sinks,
conveying confidence and European
sophistication. Add to this package the nod to
headphone users, with a very good sounding
(and quiet) headphone output section. It was a
joy to turn on the 7008 at night, nestling
back with a pair of the new Sennheiser 650
cans, and wallowing in the rich, soulful voice
of Jackson Browne, who, by the way, offers his
own interesting take on a driving experience
in The Naked Ride Home [Elecktra
62793-2].
Hitting
The Track
How
does the German engineered 7008 sound after
many punishing hours of listening by yours
truly in both a small office space and a long,
narrow living room, strapped to tough
impedance loads presented by MBL’s own 311E or
the German great, the Ascendo System F-3
loudspeakers? Like a classic Porsche, it
performed admirably, with agility, power and
endurance, without adding a scintilla of
coloration or added warmth to the
presentation. This may not be to everyone’s
liking, similar to the ride in a classic
Porsche, where every aspect of the road is
felt, and one must always be on alert for
quick and decisive action making driving a
visceral experience – not just a journey to
get from one place to another.
The experience with listening to the 7008 in
my systems for several months was quite a
similar, visceral experience. First, the
7008’s overall perspective was that you were
always ushered to a seat in the first rows of
the recording venue. Treble, midrange and bass
were always presented in dynamic, sharp and
concise manner, no matter the genre of music
or the loudspeakers utilized. Starting with
the treble region, there was a clean delivery
into the stratosphere, without any etch or
grain, except what was present on a particular
recording.
I
would describe the treble as forward, but not
overly bright or thin, more analytical than
colored. For example, on the magnificent
Chesky recording of Oregon in Beyond Words
[Chesky JD130], Paul McCandless’ soprano sax
on “Leather Cats” is captured with its proper
tone, without any thinness or reedy quality.
His squeal at the end of this fun romp is
managed quite well, although some might prefer
more warmth and fullness to his tone. On
McCandless’ penny whistle initiating the
contemplative, “Witchi-Tai-To,” the 7008
portrays this tough treble act with proper
tone, without an overly dry character. In
another test of treble presentation, ride
cymbals sounded very energetic through the
7008, without any grain or overt dryness. My
man Roy Haynes is still pulling off those
blistery cymbal flourishes, and on “Bright
Mississippi” from The Roy Haynes Trio with
Danilo Perez and John Patitucci [Verve
314543534-2] the 7008 put me in a seat right
next to his kit in this live session.
Midrange
timbres through the 7008, particularly voice,
piano, and violin, continued the forward
perspective of being very involving as well as
tonally and texturally accurate. I enjoyed
both female and male vocalists through the
7008, although some might find its
presentation of voices a bit too forward or
even strident on some bright recordings. One
gem of a recording that I enjoy for its
pristine recording of male and female voices
accompanied by bass is Rob Wasserman
- Duets CD
[MCA 42131]. On “The Moon Is Made of
Gold,” Wasserman joins Rickie Lee Jones on a
magical lullaby. Through the 7008, Rickie
Lee’s delicate mids and highs were caught in
their lightness and proper timbre, with only a
slight hint of thinness (more evident on the
smaller mbl 311E loudspeakers than when
driving the Ascendos). Other female vocalists
were similarly portrayed with energy, sparkle
and accuracy through the 7008. Alison Krauss’s
lovely vocal filigree as displayed on
“Gravity” from Lonely Runs Both Ways
[Rounder 116610525-2] was woven with such fine
detail and sparkle by the 7008 that she was
singing just for me. As for the tough project
of capturing the tonality of a banjo, the 7008
pushed Ron Block’s banjo front and center in
“Rain Please Go Away,” with all of the energy
of individual strums and picks crisply
depicted in space and time. Returning to
Wasserman’s Duets for examples of male
vocalists, in “Brothers,” Bobby McFerrin’s
unique body music is perfectly rendered, as we
sit right under his breathing body instrument
with the 7008 in place. A great rollicking
duet with Lou Reed must also be mentioned,
“One For My Baby,” where Lou and Wasserman get
electric and the 7008 conveys the immediacy
and energy of this session perfectly. Reed’s
deep distinctive voice is well portrayed, but
again, with very little warmth or lushness in
the mix, which I am more accustomed to hearing
on this cut. Accuracy, finesse and agility are
the adjectives again that come to mind to
describe the midrange through the 7008.
