  1. questionHow has Jeff Rowland remained a true pioneer of the High End audio industry for a quarter century?
    For 25 years, Jeff Rowland has established a hallmark reputation for his unsurpassed engineering artistry, for designing and manufacturing products that have consistently mustered the test of time, but also for blazing the path in the high end audio industry with trend setting technical innovati ...
  2. questionWhat is Active Power factor Correction (PFC)
    Active Power factor Correction (PFC) is a key component of Jeff Rowland’s advanced multi tier front end engineering strategy for reference grade amplification products. Not only Rowland is the World’s 1st designer to introduce PFC to high end power amplification with the Model 12 in ...
  3. questionSymmetrically Balanced Power Amplification
    Jeff Rowland is the 1st to introduce symmetrically balanced high power amplification to High End audio. Rowland has been championing the use of this topology ever since 1984, when he introduced the JRDG Model 7M monoblock amplifier, whose late versions constituted the very 1st high end audio po ...
  4. questionUltra fast, Ultra Quiet and Super Low Distortion TI Burr Brown
    Jeff Rowland is the 1st designer to apply the ultra fast, ultra quiet and super low distortion TI Burr Brown OPA1632 fully differential I/O audio amplifier modules in a high end audio product. The superior electrical characteristics and exceedingly high density of the module allows him to impl ...
  5. questionRechargeable Battery Powered Amplification
    In 1992, Jeff Rowland introduced his Model 9 monoblock amplifier flagship, the world’s 1st high power amplifier to sport twin external rechargeable battery power supplies. Ever since, Jeff continues to refine rechargeable battery DC power supplies and their application to reference grade a ...
  6. questionRemote Control Transmitters
    While remote control devices have been used in the consumer electronic industry for decades, they are relatively latecomers to High End audio preamplification. In 1989 Jeff Rowland introduced the Consonance, the World’s 1st reference grade preamplifier to sport a full function infrared rem ...
  7. questionRegulated Switching Mode Power Supplies (SMPS)
    Jeff Rowland is the first high end audio equipment designer to incorporate extremely quiet, fully regulated, and blazingly nimble switching mode power supplies in truly high end stereo amplifiers, like the Model 10 stereo amplifier and the Model 12 monoblock power amplifier released in 1999. S ...
