Integrated Amp Reviews

As strongly as I believe that the listening experience is the most reliable method of judging the quality of audio equipment, I've been biased against single-ended tube amplifiers because of their quirky measured performances. Without having heard single-ended under good conditions—much less living with an SE amplifier—I had concluded that many listeners must like them because they're euphonically colored by large amounts of low-order distortion and impedance interactions with the loudspeakers. SE amplifiers seem to be a departure from the goal of making the electronics transparent. Moreover, the range of loudspeakers suitable for SE amplifiers is so restrictive that I wondered why anyone would bother with these underpowered distortion-generators. I had fallen into a trap that I've repeatedly railed against: drawing conclusions without firsthand listening experience (footnote 1).

My entrée to high-end audio was in the late 1990s, when I bought a used pair of Cary Audio CAD-572SE tubed monoblock amplifiers to add to my Marantz CD player, Audio Note M2 preamplifier, and ProAc Response One SC loudspeakers. This system reproduced recordings with a sound that made me happier than a country boy with a glass of milk and a helping of peach cobbler. (I was reared, as my grandmother would say, though not born, in North Carolina, where Cary is based.)

My Russian neighbor's blind grandfather, Vlad, has very discriminating ears—but only when I tell him what to listen for. If I don't, he just bitches about my choice of music. And he refuses to listen to "weak" American orchestras.

Not surprisingly, Vlad worships Mikhail Glinka. "Herb! Play Russlan and Ludmilla!" When he asks for "Pyotr Ilyich," I groan and quietly put the vodka back in the freezer.

Late in 2006, I was watching John Atkinson set up a pair of DPA cardioid microphones in front of the stage of New York City's Otto's Shrunken Head to record a performance of my jazz quartet, Attention">http://www.myspace.com/attentionscreen">Attention Screen (footnote 1). Before the first set, Wes Phillips approached me. "Bob, I found a piece of equipment you must review—the Cayin A-50T integrated amp. It's only 1300 bucks and you'll love it!"

"The sound was to die for," I wrote shortly before my resurrection. I was taking notes about the sound of CH Precision's D1 SACD and CD Drive (now $38,000) and C1 D/A Controller (base price $32,000), in the demo room of Michael Woods's Elite Audio Systems, at the California Audio Show, just three months after the 2015 edition of the Munich High End show. CH Precision's L1 dual-mono, solid-state preamplifier (now $58,000), M1 dual-mono power amp ($104,000), and X1 external power supply ($17,000) had helped deliver "fantastic sound."

With its high-end heart and home-theater brain, Chord's powerful CPM 3300 integrated amplifier ($9500 with the aluminum-cylinder Integra leg option, $8950 without) is a uniquely fascinating audio product well worth considering. High-tech innards and magazine-cover good looks don't hurt either, but what originally got me interested was the superlative sound Chord products have consistently delivered at trade and consumer shows when paired with Wilson-Benesch loudspeakers.
