As a native son of Pennsylvania, I was thrilled when I learned that I would be reviewing Rogue Audio’s new RP-5 tubed preamplifier ($3500 USD), as soon as a sample was available. Rogue is based in Brodheadsville, 90 miles north of Philadelphia and about an hour from where I live. As sports fans, Philadelphians are typically long-suffering but devoted. With that as my background, it would be easy to be a fan of a local audio company. However, Philadelphians’ familiarity with recurring heartbreak has taught us to view everything with a critical eye. I anticipated the arrival of a new audio component, full of hope that it would live up to the fine reputation of Rogue’s other US-made products. What arrived surprised me in several ways.
