Truebenchmarks in audio design are rare. Major innovations such as true differential mode balanced circuitry, transformer coupling, remote controlled preamplification and battery power
supplies are prime examples of these creative leaps of faith. All are examples
of the visionary achievements of Jeff Rowland design group, a company that continuously pushes the envelope of high end audio.
For nearly
20 years Jeff Rowland has produced many of the
most widely acclaimed products in audio history.
Today, the torch has passed to such new designs
as the Model 9T Amplifier and the Coherence
Preamplifier - products that have earned numerous
international awards for product design
excellence.

The Model 102 - stereo amplifier
At Jeff Rowland Design
Group, truly great audio has been reduced to this: The astonishingly
powerful and incredibly efficient Model 102 stereo amplifier, definitive
proof that good things can come in small sizes.
Utilizing the same ICEpower™ patented power conversion technology that
has revolutionized modern amplifier design, the Model 102 packs a true
100 watt wallop in a tiny 3x13x7 inch machined solid aluminum housing
virtually immune to resonance.
The newest member of the JRDG family of fine audio components,
the 102 is the product of an obsessive quest to perform one of modern
electronics' most difficult balancing acts - the creation of clean,
dynamic power without the
unwanted and, now unwarranted, byproducts of excessive heat and mass.
The Model 102 achieves this goal by the innovative application of
impressive new developments in power supply and power output stage
design. This 10-pound marvel features a balanced input/output topology
combined with true
dual-mono power supplies to deliver handsomely on the promise inherent
in its elegant appearance.
Pound for pound, the Model 102 is simply an amplifier without peer,
producing an entrancing and satisfying musical experience far out of
proportion to its dimensions... and at a price that redefines value.
The JRDG Model 102, size one up and discover the true state of audio
excellence, from the Jeff Rowland Design Group.
Announcing a new era in amplifier
technology . . .
Model 302 Stereo Amplifier
When attempting to
describe an achievement so spectacular as to be proclaimed
"revolutionary", words often fail to convey the depth of
that achievement. Our listening persuades us that the Model 302 exposes
the music to a greater degree than previously experienced - and yet
the familiar Jeff Rowland sonic lineage is evident - a lineage steeped
in constant efforts to develop products that honor the music.
Utilizing an extremely
efficient output topology that maintains very precise control over all
electrical parameters, the 300 Series amplifiers communicate the
musical gestalt in startling fashion. This level of sonic
sophistication is made possible by concentrating on physical and
electrical parameters that adversely affect the delicate musical
waveform.
The elimination of
deleterious resonance can only be achieved by addressing the physical
structure of the amplifier, our most non-resonant to date. In addition
to pioneering the use of balanced, transformer-coupled circuitry in
audio amplifier design, the utilization of commercial-grade
power-factor correction modules ensures that anomalies related to
"dirty" power never influence the music signal.

The Model 201 Mono
Amps
A new amplifier design, like all other creative
pursuits, borrows
lessons learned from previous
successes.
The
Model 201 is the direct beneficiary of the
knowledge gleaned from the development of the
300 Series. While the 300 Series represents our
no-holds-barred utilization of these new
concepts to achieve the pinnacle of audio
reproduction, the Model 201 exploits those
lessons learned to create a product that
extracts the full capabilities of these new
technologies, yet accomplishes this feat in an
extremely efficient, ecologically-sensitive,
low-cost package.

In 1996, the Synergy Stereo Preamplifier
was released, creating a benchmark upon which other preamplifiers were
to be judged. Debuting with an extremely compact and non-resonant
chassis design with a separate AC power supply, the preamplifier
immediately won praise for its outstanding presentation of the naturally
recreated musical event.
In 1998 the Synergy was upgraded to
Series II status, adding the flexibility and sonic benefits afforded by
audio transformer coupling and a second pair of preamp-level outputs.
This change in circuitry improved the unit's capacity to interface with
diverse associated equipment.
In December of 2000, a new amplification
board utilizing modern "small geometry" surface-mount
technology gleaned from the Coherence II Preamplifier and the Model 10,
Model 12, and Model 112 Stereo Amplifiers was designed and released for
the Synergy II, lowering noise and distortion, and shortening signal
paths dramatically. The current Synergy IIi presents a musical
presentation that fully complements the current series of JRDG
amplifiers and showcases their benefits without intruding upon the
original source signal. Improved transient response, speed, and
dynamics, increased transparency and neutrality, and an elevated level
of detail retrieval and resolution combine to bring the Synergy IIi to a
performance level significantly higher than was thought possible –
without an increase in cost. The Jeff Rowland Design Group Synergy
Series IIi - embracing our long tradition of applying state-of-the-art
technology in the name of music.
The Model 112 Stereo Amp
The Model 112's feature the two-tiered chassis
design in which the power supply is separated from the amplifier circuitry. The Model 112's internal design effectively
isolates sensitive signal circuitry from unwanted electromagnetic field contamination. A powerful toroidal power transformer
gives the Model 112 the ability to handle even the most difficult loudspeaker loads with ease. The amplifier provides a full
complement of balanced and single-ended inputs, a unique "wheel lock" binding post for secure loudspeaker cable connection and an
on/off DC input jack for home theater applications.
All three of these amplifiers are encased in
a machined solid aluminum billet chassis (an elegant testament to Jeff Rowland Design Group's well-earned reputation
for superior artistic design) providing a completely non-resonant and RF/EMI shielded platform from with the musical
presentation can begin.
