Spectron
Musician III Signature Amplifier
The latest
thinking from digital guru John Ulrick is the Musician III.
His previous creations, Musician and Musician II, gained
status in the world of digital amplification as the best of
the best. That
statement has been supported by my experience over the
years. in working with I’ve sold a good number of Spectron
amps. Over that time I’ve had clients who have compared the
Spectron to every other make and model of digital amps
available. Time and time again the Spectron has been the
winner.
So what is it about the
Spectron amp that makes it so good? Maybe it’s what it doesn’t
do that makes it special. The Musician III Signature has so few
artifacts that it is difficult to find fault. Most amps have a
describable fingerprint they imprint upon the music that
defines its character. That isn’t necessarily bad mind you,
especially if you seek to tune the system in a specific
direction. The Spectron just seems to be about as evenhanded
as it gets. And that’s good, if you are looking just to pass
the signal unfettered.
One of the first reviews out on the Spectron amp
described is as neither tubes nor solid state, suggesting it
had the best of both worlds; the lack of grain and harshness
that accompanies many solid state designs, and yet possessing
the dynamics and control so valued in the genre. I would agree
with that assessment.
The evolution from the
Musician to the Musician II, Musician III and now the Musician
III Signature has been
a fun one to watch, or hear, as the case may be. Without a
doubt, the Musician II is certainly one of the World’s great
amplifiers, regardless of genre.
"I now consider the Musician III the most musically
accurate and well balanced solid-state amplifier I have
reviewed to date. Furthermore, only a small handful of tube
amplifiers come close to equaling its musicality. Its audible
subtlety, along with massive power and headroom, fine-grained
articulation of musical detail, and sheer speed add up to a
very special instrument for reproducing music of every kind.
At $4995, this remarkable amplifier is a consummate bargain
that belongs on the must-hear short list of every serious
audiophile." —Wayne Donnelly
A Matter of Balance Review by Greg Weaver:
"Using the latest realization of John Ulrick's near
quarter century dream has brought me substantially closer to
the magic of the music I love so dearly. This is the second
milestone product I've had the pleasure of reviewing this
year… The Spectron Musician II is a remarkable achievement,
truly pushing the state of the art.
I don't know
of a single amplifier, at any price, that would embarrass the
Spectron Musician II. It has more successfully achieved that
delicate balance between brute force and artistic expression
than any amplifier I've had the pleasure of hearing. And at
$3500, that makes it possibly the best value in amplification
available today. Run, don't walk, to your nearest Spectron
dealer and hear what you've been missing."
"Anyone looking for powerful
yet highly refined amplification would be foolish to ignore
the Spectron Musician III. I believe it will serve me well as
a standard against which to measure other amplifiers. So I'm
keeping this one. Superior audio indeed!" Wayne
Donnelly, Enjoy The Music, Superior Audio
"Tonally, the Musician III is as neutral as they
come—smooth across the octaves, and with top-notch
interconnects and a good warm-up, not a whiff of spotlighting
in the upper octaves. Treble is pristine and displays none of
the whitish grain or transient blur that plagues many amps,
Class D or otherwise. I have to admit that regardless of
'Class' the Spectron Musician III punched my time clock like
few other amps I've heard." The Absolute Sound

Remote
Sense Speaker Cables
A totally unique concept,
the Spectron Remote Sense Speakers Cables seek to do something
no other cable design has ever attempted; include the speaker
cable in the feedback loop of the amplifier.
Feedback in an amplifier
sends some of the output signal back to the input to corrects
for any nonlinearities created in the amplification process.
Since no amplifier circuit is perfect, feedback can help to
improve linearity and reduce distortion.
Remote sense is a special
purpose speaker cable to be used with Spectron amplifiers.
These literally extend the feedback loop of the amplifier all
the way to the speakers. It is implemented by use of
Spectron's special four conductor speaker cable with a Neutrik
connector that mates to a Neutrik receiver on the rear of the
Musician II. Two of the wires connect the amplifier to the
speaker just like a conventional system. The second pair
senses the actual voltage at the speaker end of the cable.
Spectron's exclusive remote sense technology is an important
step in compensating for the otherwise unavoidable loss in
fidelity caused by even the best speaker cables. By comparison
conventional amplifiers can only sense the signal at the
output of the amplifier. All wire has resistance, inductance
and capacitance. Even if there was a perfect metal, (no
resistance) the effects of inductance and capacitance would
still be there. Remote sense compensates for these effects.
Spectron's remote makes corrections for errors in both the
amplifier and the cable together, not just the amplifier.
While this is the most advance speaker cable technology
available, the cost for remote sense cables is actually less
than using the high end cables with exotic materials.
Length: 3, 5, and 8 meters standard with any length available
on special order.
Termination: A 4 cm x 4 cm x 10 cm metal box with two
connectors with two 6-32 threaded holes on inch centers to
allow male banana plugs to be screwed in. These two banana
plugs can be plugged directly into a speaker with female
banana plugs on centers or two wires can be mounted with
spades.
Price: $549 per pair for any length up to 5 meters. $649 per
pair for 8 meter length. Longer lengths available by custom
order at $20 per meter per cable beyond 8 meters.
