Marantz Model 30 integrated amplifier

DeKalb, Illinois, 1971: When I was in college, my anthropology professor would invite me and a few of his other favored students to his house for fondue parties. We sat on shag carpet around a glass-topped coffee table, drank wine, and dipped vegetables in molten cheese. The stated purpose of this rite was to discuss Margaret Mead or Franz Boas, but that was obviously a ruse. The gathering was really about excessive pot smoking accompanied by coughing fits and the telling of ridiculous stories, all while playing LPs on his top-of-the-line Dual turntable/record-changer.

Marantz Model 40n integrated amplifier

On a cold, clear February morning, I attended my first in-person press event since the beginning of the pandemic. Marantz had invited me to a small group session in a suite at the Equinox Hotel at Hudson Yards but gave no indication of what was in store. After two years without live press events or audio shows, I was not going to spurn the offer no matter what would be presented: I was hungry for hi-fi. Upon arrival, I learned that Marantz would be featuring just one new product, a streaming integrated amplifier, the Marantz Model 40n ($2499). Sure, I'm in.

Mark Levinson No.383 integrated amplifier

When I learned that Madrigal Audio Labs was marketing their first integrated amplifier, the Mark Levinson No.383, I felt this was a big change for the Connecticut company. Mark Levinson literally started the high-end marketing revolution back in the early 1970s by manufacturing cost-no-object separate amplifiers and preamplifiers. The purist designs had one overriding rule: employ the simplest circuit path possible. Each amplifier or preamplifier used only individual circuit-board components (no integrated circuits) and had a minimal number of controls, eschewing elaborate switches and tone controls. Mark Levinson Audio Systems and its successor, Madrigal Audio Laboratories, has continued this philosophy of separate components for the past 25 years.

Mark Levinson No.5805 integrated amplifier

Mark Levinson isn't known as a budget brand, and most people would not consider $8500 a budget price for anything short of a new car. One could argue, though, that Levinson's new No.5805 integrated amplifier ($8500 with DAC and phono stage) is a budget component—combining high performance and build quality with a price tag that's moderate by hi-fi standards. Plus, there's a lot of functionality in one box.

Mark Levinson No.585 integrated amplifier

In July 2000, I reviewed the Mark Levinson company's first integrated amplifier, the No.383, and found that its sound had "clarity, transparency, liquid mids and highs, with dynamic contrasts." Also evident were the No.383's power-output limitations, the result of building large power supplies and heatsinks into a single case that had to fulfill multiple functions. Still, the No.383's price of $5900 was much less than the total cost of the equivalent in Mark Levinson separates. Later, in April 2007, I reviewed a similarly powered integrated amplifier, Bryston's B100-DA ($3195), which included a built-in DAC.

Mastersound 300 B S.E. integrated amplifier

Although she'll deny it, my wife thinks ill of me because I've failed to buy her a new Mini Cooper. I can point to a number of things in my defense—especially the Mini's lack of all-wheel drive, which we need for climbing our quarter-mile driveway in bad weather, and its insufficient cargo and passenger space—all of which would constrain a Dudley-owned Mini Cooper to recreational use only. And a new round of car payments would be difficult to justify for those reasons: not because I'm cheap, and not because I'm too old to appreciate a car that's fun to drive.

Mastersound 845 Compact integrated amplifier

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.

McCormack Micro Integrated Drive headphone amplifier

What, I hear you asking, is an integrated drive? The MID is part of McCormack's much lauded "Micro" series (see my review of their Micro Line Drive in Vol.18 No.6), which are designed to offer the same dedication to quality as McCormack's full-size components, but at a lower price (and in a smaller package). The MID was initially the Micro Headphone Drive, sporting two ½" stereo phone-jacks on the front panel, a two-position input switch, and a volume control. The rear boasted two inputs and an output (controlled by the volume pot). It was designed to be a high-quality headphone amp and a minimalist preamp. In this configuration, I ran into it at the 1995 WCES where—almost as a gag—Steve McCormack had made up a few ½" stereo phone-plug to 5-way binding post connectors. He could, he explained, run small speakers from the headphone outputs. There was a serious purpose behind the joke, of course. Showing that the MHD could drive speakers spoke volumes for its ability to drive headphones.
