Integrated Amp Reviews

Stereophile has reviewed two integrated amplifiers from Chinese manufacturer Cayin in the past: the A-50T, which I wrote about very positively in March 2008, and the A-300B, which Art Dudley reviewed in February 2007. So when I read about Cayin's $2195 SP-10A integrated amplifier, which has a wood-covered sleeve, just like the old Marantz and McIntosh gear and offers 38 watts of push-pull power, in our coverage of the 2008 CES, I put in on my must-write-about list.

"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.

The last few years have seen a flood of new integrated amplifiers in an audiophile market traditionally wedded to separate preamps and power amps. That might reflect the fact that integrated amps make a lot of sense, and not only because they usually cost less than equivalent separates. The latter gained a foothold in audio's Paleolithic era, when tubes were the only game in town. Tubes generate lots of heat—an enemy of electronics—and separating the preamp stages from the output devices kept this under control. Yes, there were integrated amplifiers back then, but they were generally of very low power—25Wpc was once considered monumental.

The search for signal transparency has led to much experiment and debate concerning losses in fidelity that can be traced to the preamplifier or—as it's more often and awkwardly called these days when the phono stage is omitted—the "line controller."

Creek Audio founder/designer/co-owner Michael Creek is a quiet, friendly, unassuming man. Unlike some ego-driven electronics designers who tout their products very loudly from their pulpits, Michael Creek has been quietly designing high-quality, musical, and affordable integrated amps in black-metal boxes for nearly 20 years. His target market is the passionate music-lover who wants something a notch above an entry-level NAD or Rotel receiver, but whose bank manager would frown on splurging on electronic separates.

The one thing I've liked about designer Mike Creek of Creek Audio as much as his design talent is his predictability. I've been following his integrated-amplifier designs for nearly 20 years now, having reviewed, in sequence, the CAS4140s2 (for another magazine), the 4240SE (Stereophile, December 1995, Vol.18 No.12), and the 5350SEhttp://www.stereophile.com/integratedamps/327">5350SE; (March 2001, Vol.24 No.3). In each case, I was sufficiently impressed with the review sample that I bought it and made it my new reference in my second, affordable system. The predictable part comes from Creek's traditional nomenclature: an "s2" or "SE" (Special Edition) designation has always denoted a modest upgrade, and a numerical uptick in the model number a more significant upgrade, the level of significance denoted by the specific digit being increased. Hence, the update from 4240 to 5350 is intended to indicate a greater improvement in sound than the update from 4140 to 4240.
