The B-60 Integrated Amplifier
A Step Up.
By Fred Kaplan
One of the more notable trends in the hi-fi business
the past year or so is the sudden ascendancy of that centrist product,
the integrated amp. Though long-popular in Britain, where the indigenous
hi-fi industry has made a specialty of the genre, it's been a category
of goods all-but-unmarketable in the US. The masses consider it
too exotic, preferring receivers, which hold in a single box not
only an amp and preamp but a radio tuner, as well-while the high-enders,
with their purist insistence on separate components for separate
functions, deem it not exotic enough. But now the mood is swinging,
apparently from both directions. From "below," a surging
stock market has set many once-indifferent consumers on an upwardly
mobile road where, among the maze of other fancy electronic toys,
the proliferation of compact discs and home-theater systems has
nudged them toward the fineries of "good sound." From
"above," a sheer shortage of shelf space, perhaps combined
with the outlandish prices charged these days for a simple one meter
pair of cable to connect a preamp with an amp, has triggered a compulsion
to wind down. Of course, all this is theorizing. The fact, however,
is that integrated amps are spreading, not only from the usual suspects
in the upper-mid-fi ranks, but also-as has been documented in these
pages from such entrenched highend firms (which never would have
stooped to the task a few years ago) as Krell, Goldmund, Conrad-Johnson,
Audio Research, and (we now approach our subject at hand) Bryston.
The Canadians at Bryston designed the B-60 integrated
amp primarily for the European and Far Eastern markets, but expanded
the production line when they discovered, much to their surprise,
that it was selling briskly in North America, too. Given the broader
trend in the market, there's no mystery why the B-60 should be making
waves. It's a sleekly handsome, extraordinarily compact machine,
yet sports four pairs of input jacks, a tape and an audio input
jack for a video source, plus two more that can be used either for
a surround-sound processor or to turn the unit into a dedicated
preamp or power amp. Like many mass-market products, it also has
a headphone jack in the front and a power-socket in the back. The
only thing it lacks, along these lines, is a phono-section (made
available since first reviewed), though, alas, the market for such
features has diminished (and, for those who still spin LPs, Bryston
sells a couple of separate phono-stage preamps: the BP-1 moving
magnet for $750, the TF-1 moving coil for $550).
I suspect those who are rising from the bog
of receivers will find the B-60 a revelation, and those retreating
from the tangle of separates will be find it a pleasant surprise.
When it comes to capturing the vital midrange of music (voices,
woodwinds, small string ensembles), the Bryston is impressive
by nearly any Standard, not just for its size and price tag. On
Afterglow (Mapleshade), you can sense singer Kendra Shank's palpable
presence. Dawn Upshaw sounds properly, meltingly, glorious on
Gorecki's Third Symphony (Nonesuch)-and, speaking of that recording,
you can see the cellos before you toward the start of the first
movement. On Analog Productions' gold-CD reissue of Spirit Sensitive
(or the less spectacular but still quite nice aluminum disc on
India Navigation), Chico Freeman's tenor saxophone projects the
combination of warmth and brassy edge that one can usually hear
only through much more expensive electronics.
The B-60 also does an excellent job of retrieving
the ambiance and (if it's captured on the disc) the seamless spaciousness
of a recording space, whether it's a studio, a concert hall, a
jazz club, or a dive. The distance between the front and back
rows of a stage and the layers of air between them are also well-delineated.
Instruments and singers take on a natural 3-D focus.
Still, the Bryston has its weak points, and
whether you can tolerate them will depend on your taste. Its most
serious shortfall lies in the nether regions of the bass. The
very lowest contrabass notes at the start of Gorecki's Third are
barely audible. On "Maqam Hedjaz," from the Eduardo
Paniagtma Group's Danzas Medievales Espanoles [m-a Recordings],
the lowest tones of the bendir, a big bass drum, sound not just
quieter than its midrange tones, but also less distinct, almost
as if it they were coming from a different drum entirely. (However,
the resonance of the drum and the echoes from the reverberant
church, in which the session was recorded, come through fine.)
Even when a bass violin plucks or bows somewhat higher notes,
they sometimes lose their distinctiveness -or vanish - when massed
strings, or simply a large number of any instruments, enter the
fray.
I suspected this weakness came from what must
be (in such a small box) the B-60's rather diminutive power supply.
The issue, I figure, is not so much wattage (rated at 60 per channel,
with clipping avoided up to 71), but rather power reserves. However,
upon opening up the case, I saw two reasonably large-and, given
the size of the overall unit, amazingly hefty-twin custom torodial
power supplies (one for each channel). In fact, a chat with the
folks at Bryston reveals that, in terms of parts and circuitry,
the B-60 is exactly the same as Bryston's B-20 preamp (which alone
costs $1495) and its 2B-LP power amp ($850) combined, all in one
box. So who knows what's going on here? Whatever the cause, when
pushed to its limits, the B-60 has little headroom for momentary
expansion. Certainly, at very least, the amp should not he hooked
up to speakers that are difficult loads. (For instance, the Platinum
Quattros, which are said to require at least 100 watts per channel,
never opened up when driven by the Bryston-though the more efficient,
and considerably easier, Gallo Nucleus Solos, which were used
for this review, very much did.) The owners manual states, "impedance
less than 4 ohms not recommended."
This limitation may also account for the amp's
slight softening of transients. Back to the Kendra Shank disc:
the various cymbals, bells, and shakers on Steve Williams' trapset
lose some of their high octave zing and shimmer; there's also
a bit amiss in the forward edge of his drumstick blows.
A competing integrated amp, the almost identically
priced ($1400) Naim Nait 3-R (which Andrew Keen admired in the
April Fi), is cleaner and clearer when it comes to bass tones
(and overtones), percussive attacks, and dynamic contrasts. However,
the Bryston is warmer, less strained, and also more detailed at
getting the midrange right (especially voices) as well as the
air and space in which the music blooms and swirls around. Ah,
to find the little, sub $1500 integrated that fuses the best of
both units. I suspect (though I base this only on memory, which
might well be flawed) that the Musical Fidelity (known in the
US as British Fidelity) A-1, which in its heyday sold for a mere
$700, may have fit the ticket, but it has been discontinued and
was never available for very long in the US anyway.
Still, I do not wish to diminish the Bryston's
considerable appeal. What it does well, it does at least as well
as many separate amps or preamps that, together, cost a great
deal more. And what it does less well, it does much, indeed startlingly,
better than the great bulk of gear owned by those for whom the
B-60 would represent a big step up.
