Corus Preamplifier
Elegant
main chassis milled from ingots of non-resonant aircraft-grade aluminum
houses all delicate audio and control circuits. Ground-breaking AC power
supply is segregated in its own handsome external milled aluminum unit.
The
Corus Stereo Preamplifier delivers the Jeff Rowland hallmark of a sensuous
and grain free musicality, combined with astonishing transparency and low
level resolution. A broad 3-dimensional sound stage materializes into the
physical listening space, where instruments and vocalists assume the
textured appearance of solid existence.
The
preamplifier yields exceptional frequency extension and linearity, with
magnificent bass definition, an extraordinarily complex exposure of
harmonic structure, and a sweetly filigreed treble. The Corus yields
amazingly nuanced low level detail and micro-dynamics, and outperforms
every previous Rowland preamplifier with its transient speed, staggering
authority, and breath-taking macro dynamics. Only the transcendent
resolving musicality of the Criterion battery-powered Preamplifier ever
yields an even superior listening experience. |

feedback and virtually free of internal and external EMI field contamination
and mechanical vibration.
The
Model 625 delivers a sensuous grain-free musicality of unparalleled
transparency and low level resolution that blossoms from a rich velvety
silence and blossoms into the pure enjoyment of your listening experience. |

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.

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.
