An Integrated Amplifier Shootout: Ayre Acoustics EX-8 vs Cambridge Audio

In our February 2019 issue, when I reviewed a new integrated amplifier from Colorado-based Ayre Acoustics, I concluded that "the EX-8 Integrated Hub is a high-end contender at a competitive price" (footnote 1). In that review I promised a Follow-Up in which I would compare the EX-8 with Cambridge Audio's Edge A integrated amplifier, which Ken Micallef had positively reviewed in our January 2019 issue (footnote 2). While I'd enjoyed my time with the EX-8, I'd found its balance rather on the light side, and that it projected voices somewhat forward on the soundstage.

CH Precision I1 Universal integrated amplifier

"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."

Ayre Acoustics EX-8 Integrated Hub integrated amplifier

It's a high-end audio truism: Successful companies are founded by a creative engineer or entrepreneur with a vision. So what happens when the founder is no longer around? While Mark Levinson is an example of a brand that not only survived the exit of its leader but thrived, speaker manufacturer Thiel dwindled after co-founder Jim Thiel died in 2009, and eventually closed up shop. Colorado company Ayre Acoustics was faced with this problem when founder Charley Hansen passed away in November 2017.

Cambridge Audio Edge A integrated amplifier

One summer in the mid-2000s I purchased a pair of Cambridge Audio components for my red-headed, tango-dancing Texas girlfriend. She quickly saw through my ruse to install some solid hi-fi in her New Jersey home away from home—but eventually she acquiesced, and soon Michael Martin Murphey (she), the Beatles (me), and Miles Davis (us) filled our weekends with music. Inspired by a Sam Tellig column I read around that time, I paired a Cambridge Azur integrated amplifier and CD player with a pair of Triangle Titus XS minimonitors. The sound produced by this quartet was clean, precise, and altogether pleasurable—for a total of about $1300.

Cary Audio SLI-100 integrated amplifier

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.

PS Audio Sprout100 integrated amplifier

The original PS Audio Sprout, which I reviewed in the May 2015 issue, showed newcomers an easier, smaller way to amplify music recordings in the home. At $599, the Sprout100 costs $100 more. It fixes a few of the old Sprout's weirdnesses: no power-on indicator light, no remote control, five-way binding posts that weren't really five-way. It also doubles the Sprout's class-D power output into 4 ohms, from 50 to 100Wpc (or 50Wpc into 8 ohms), and adds a few sonic and mechanical enhancements.

NAD C 328 integrated amplifier

In 2015, the venerable Canadian audio company NAD introduced its soon-to-be-popular D 3020 integrated amplifier ($499), which combined 30Wpc output, streaming capability, and an onboard DAC in a slick, contoured case. NAD's latest D/A integrated also smartly combines trend with functionality, lifestyle convenience with technological advancement. The C 328 Hybrid Digital amplifier ($549) goes its older, smaller sibling a couple steps better in features, while reverting to NAD's traditional look: an unfancy box finished in a dark shade of matte gray with subtle white lettering and logo.

Anthem Electronics STR D/A integrated amplifier

Stop me if I've said this before (okay, I have): There's much to be said for integrated amplifiers. While separates have long dominated high-end audio, an increasing number of integrated products not only bundle a preamp and power amp, but sometimes add digital inputs of various flavors, phono stages, bass and treble controls (long on life support in audiophile gear), and more.

Rogers High Fidelity 65V-1 integrated amplifier

"Okay, all you high-rolling audiophile know-it-alls—what is the argument against amplifiers that operate in high-bias, class-A, single-ended mode, with the lowest possible parts count? Is there a better strategy for beauty, rhythm, color, texture, and easy-flowing musical verity? I think not. And please explain: Why has mainstream audio gone to such ridiculous and expensive lengths to avoid building and selling precisely these sorts of amps?"
