Integrated Amp Reviews

My first car was a decrepit, mustard-yellow Peugeot 304 with a navy hood. The blue hue wasn't a fashion statement; after an accident, the previous owner had gone to a salvage yard where only a blue replacement could be procured. When he grew sick of the car—because it made him look "like a frickin' ad for Ikea"—I paid him 600 Dutch guilders for the old heap, the equivalent of about $300 US. . .

Years later, when I got into hi-fi, I thought of that car and subsequent ones. What stood out to me most about high-end audio was: separates.

In the 1960s, my dad gave me a Panasonic receiver with two cube speakers, just in time for the advent of FM stereo radio in the San Francisco Bay Area. Out of the blue one night, he just walked in with it. The receiver allowed me to plug in a record player, though I only had a few LPs. Later, when I went off to college, my mom took me shopping for a new stereo. I chose a Kenwood integrated amplifier—without a tuner but with the capability to plug in a tape deck, which I did. During my undergrad years, it served me well. Later, I switched to an NAD receiver, which allowed me to listen to the radio again.

Back in the 1950s, Cesare Sanavio, then a new electronics graduate with a specialty in output transformers for tube amplifiers, began his career in radio and television, traveling to various locations outside his native Italy to apply his expertise. Eventually he settled in Paraguay and started designing tubed sound systems for public installations, teaching his son Luciano the art. A few years later, Sanavio and his family returned to Italy. There, he worked as a consultant to several hi-fi companies. Finally, in 1994, drawing on decades of accumulated knowledge of tube-amplifier design and manufacturing, and a particular focus on output transformers of the highest quality, Cesare Sanavio and his two sons, Luciano and Lorenzo, formed Mastersound.

When Cesare Sanavio died, Lorenzo and Luciano continued operations. In 2015, the company re-formed, with some new international business connections and a new CEO, Antonio Ferro.

Before this month, I'd never experienced Rotel amplification in one of my own systems, but I have memories of how their amplifiers sounded back in the early 1990s. In those days, at audio shows, I would audition every Rotel amp I could find; I was especially interested in their $369, 60Wpc RB-960BX. I was curious about that model because it was the number-one competitor to the 60Wpc darling of the audiophile proletariat: Adcom's GFA 535 II. My friend Corey Greenberg compared these two popular amps in Stereophile and concluded, "The Rotel is for the budget-minded music lover who wants a good, solid little amplifier that's not going to make listening to music a trying experience."

My first high-end component was an Audio Note M2 preamplifier, which I bought from former Audio Note distributor/current Stereophile contributor Michael Trei. (Senior Contributing Editor Herb Reichert was Michael's partner in that 1990s-era Audio Note venture.) Herb can regale you with tales of motoring across the Soviet Union in an unheated Mercedes, trunk full of Audio Note components and American dollars, but that's a story for another review (most likely to be written by Herb).

This morning, I received an email from John, my DIY friend in Europe, saying how happy he was. He had just finished building a new power amplifier using two UcD250LP class-D amplifier modules. He described the results as "quiet, clear, clean, effortless class-D power," adding, "What more could I ask for?"

Sometimes it's good to step outside your comfort zone. In fact, I relish new and novel experiences. It's a major reason I enjoy attending hi-fi shows and events: for the chance to see and hear new things—new hi-fi equipment, especially equipment that's groundbreaking or unusual.
