Why Jeff Rowland has so dramatically changed course, and has adopted switching technology for power supplies and power amplification?

In 1992, by challenging the limits of the possible in audio engineering through advanced topologies and revolutionary rechargeable battery twin power supplies, Jeff imparted his Model 9 monoblock power amplifier flagship its gorgeous musical footprint: a tremendous staging and dynamic power, matched by a unique intimacy and grain free musical presentation, with just a touch of that openness and transparency which would become the hallmark of his latest creations. 

Rowland has sought musical truth through his leading design work for a full quarter century. He pushes the state of the technological art as a means of raising the artistry of the possible in reproduction of musical beauty, while remaining consistent with long held personal esthetic ideals.

As new technologies become available, Jeff selects the most promising among them. He harnesses their full potential as basic building blocks in his continuous artistic quest of evolving his creations’ ability to extract ever subtler harmonic and dynamic nuances from music recordings.

Through the application of the most advanced technologies, like highly regulated switch mode power supplies, as well as active Power Factor Correction (PFC), applied to his most advanced class A/B and D designs, Rowland continues to increase dramatically the control over speakers of any load, resulting in even superior staging and image resolution than the celebrated Model 9HC, while frequency extension, linearity, and transparency today reach levels unherd just a few years ago.

The Criterion reference linestage, the Model 625 class A/B stereo amplifier, the Model 301 class D monoblock amplifier, and the Continuum 500 integrated amplifier, are some of today’s most compelling instruments for music reproduction. They are destined to become tomorrow’s treasured heirlooms. They yield a neutral yet sensuous musicality, complemented by a superior imaging, musical resolution, and authority that let the listener reach into the emotions of the musical experience deeper than ever before, while they remain true to the classic JRDG hallmark of the grain free presentation yielded by such masterpieces as the Model 9HC monoblock amplifier.
