The internal construction uses a balanced topology, which contributes to clean and detailed sound reproduction. The amplifier is equipped with transformer-coupled inputs, which facilitates compatibility with various audio components and minimizes unwanted noise. In addition, the 625 features an efficient switching power supply, which provides stable performance under various conditions. The combination of these features results in a listening experience that is both transparent and immersive.
Brand history
Jeff Rowland Design Group was founded in 1984 by Jeff Rowland. Since then, the company has been designing and manufacturing equipment with advanced technologies. Products are housed in precision-milled aluminum enclosures that serve to protect against electromagnetic interference. Manufacturing takes place in the United States, with an emphasis on mechanical accuracy and material quality. Designs employ balanced architectures, discreetly built circuits and great attention to resonance control. The selection of high-quality components and precise assembly processes underlie each device. For power supply applications, techniques such as active PFC (Power Factor Correction) are employed and isolated converter modules are used. The products undergo extensive quality control and tuning on a piece-by-piece basis. The company has maintained a consistent design philosophy since its inception and operates from the same manufacturing facility in Colorado Springs.
