Integrated Amp Reviews

Once upon a time, reviews of Musical Fidelity components frequently filled pages in Stereophile. But in all my years covering audio shows, I can't recall blogging about any of the company's products, not even once. So, when my editor offered a review of the new M8xi ($6490), a hefty 101lb dual-mono integrated amplifier that includes a DAC, I seized the opportunity to fill a black hole in my consciousness. (Kindly cast aside thoughts that it would take more than a hunk of audio equipment to fill the black hole in my brain.) As long as I didn't break my back lifting the M8xi, solo, to the top shelf of my rack—for this I humbly beg assistance from spouses, neighbors, and friends—new vistas were in store.

Yamaha: The name evokes memories of my youth when those much-coveted receivers were out of financial reach, leading me to rely upon entry-level Kenwoods and Pioneers and others that sounded worse. Everyone who ever had a cheap receiver blow up—that's what caused me to move from Kenwood to Pioneer—or heard an old Akai that made LPs sound like 128kbps MP3s, please raise your hands.

Finally—a way to get a handle on the sound of Aavik Acoustics electronics. I'd heard the Danish-made components many times at shows, but always in the context of Ansuz Acoustics cables and Børresen Acoustics loudspeakers. As much as the threesome was inevitable—all three companies are owned by Michael Børresen, Lars Kristensen, and a third shareholder—there was no way to determine the unique sound of each component in the mix.

I am the world's worst consumer. Not only have I made more than my share of disastrous purchase decisions, I'm also inexplicably luckless: If there's one defective sample or repack in an inventory, it will find me.

I'm also a deceit magnet, and I'm spineless: More than once in my life, I have made abominable purchase decisions solely to please a manipulative salesman or a disinterested third party (read: girlfriend). There is abundant photographic evidence that I don't know how to shop for clothes, my glasses are wrong for my face because I trust the advice of opticians with bad or no taste, and the less competent/more antagonistic the barber, the likelier I am to say "Great job, I love it" and tip them 50%. If I were smarter, I might actually be rich by now, or at least comfortable.

In Herb Reichert's review of the original Schiit Audio Ragnarok integrated amplifier, he wrote, "Schiit Audio's Ragnarok [is] the first amplifier of my experience that plays earth and sky, mind and body, brown eyes and blue, speakers and headphones, with equal narcotic intensity." Herb's colorful conclusions so persuaded me of the Ragnarok's worth that, when Schiit Audio's Jason Stoddard and Mike Moffatt announced the impending release of the Ragnarok 2, I pitched a Stereophile follow-up review.

High-quality playback of digital audio is evolving in two opposed directions. One is where a smart wireless loudspeaker, like the KEF LSX or DALI Callisto 6 C, needs to be connected to a simple source of data. The other is where a smart amplifier takes the data from wherever it needs and sends it to a pair of dumb loudspeakers. NAD's Masters Series M32 integrated amplifier ($4848 with its optional MDC DD-BluOS module), which I reviewed in May 2018, is a great-sounding example of the latter approach.

In the spring of 2019, NAD introduced the Masters Series M10 ($2749). At first I assumed that the M10 was a stripped-down, less-powerful version of the M32, but the new amplifier offers a unique set of features.
