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.
"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."
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.
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 homebut 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 pleasurablefor a total of about $1300.
My Russian neighbor's blind grandfather, Vlad, has very discriminating earsbut 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.
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.
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.
The Emitter II Exclusive integrated amplifier, from German manufacturer ASR Audio (footnote 1), challenged my idea of what I could expect from a solid-state amplifier and my thoughts of what might be the best amp for driving a pair of Quad ESL loudspeakersrevelations that were more or less inseparable. After hearing my friend and former neighbor Neal Newman drive his own ESLs with a ca 1975 sample of the Quad 303a solid-state amplifier rated at 45Wpc into 8 ohmsand after my experiences, in 2016, driving my ESLs with a borrowed sample of the 18Wpc, solid-state Naim Nait 2, I began to think that Quad-friendly transistor amps are easier to find than their tubed counterparts.
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.
"Okay, all you high-rolling audiophile know-it-allswhat 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?"
The first time we saw an AR amplifier (at a Hi-Fi Show), we were struck by its bland, almost antiseptic appearance. Amidst all those other audio products that looked as though they had been high-styled for Madame's boudoir, the unadorned simplicity of the AR amplifier made it stand out like an Eames chair at Williamsburg.
We're well past the day when the sound of top-tier tube amplifiers can be described as "syrupy" or "too warm" or producing "soft bass." Equally true, solid-state designs have reached a level of maturity at which "sweetness," "fluidity," and "flow" are similarly applicable descriptors, thus smashing the cliché of "cold transistor sound."
When I asked NAD for a sample of their Masters Series M50.2 digital music player, which I reviewed in the December 2017 issue, they also sent me a Masters Series M32 DirectDigital integrated amplifier, which had also been introduced at the 2017 Consumer Electronics Show. Costing $3999, the M32 offers a continuous power output of >150W into 8 or 4 ohms. The M32 is the same size as the M50.2, and its smart-looking combination of matte black and gray-anodized aluminum panels make it look identical to the player, except for the black volume-control knob to the right of the front panel's four-color touchscreen, and the ¼" headphone jack at bottom left. It even has the same eight ventilation grilles inset in the black top panel.
When Michael McCormick, president of Bel Canto Design, suggested that I review their Black ACI 600 integrated amplifier, I accepted without hesitation. As wonderful as my reference system may sound, its dCS digital front end alone comprises four boxes and a web of cables complex enough to send many a spider spinning. Given the choice between connecting that front end to a pair of expensive, enormous monoblockswith their similarly expensive AC cords and equipment racks/isolation platformsor to a single, visually elegant, 45-lb box that costs $25,000, produces 300Wpc into 8 ohms, and requires only a single power cord and shelf, I think many an audiophile, even those with lots of money, might gravitate toward the latter.
Audiophiles are oblivious to the low-end music-reproduction medium that's currently staging a comeback: the cassette tape (footnote 1). I've adopted the cassette craze in my own small way. I glory in the trusted mixtape, which I play in the stereo cassette deck of my 1990s Toyota. An automobile is a dearly cherished possession in New York City; when I cruise the outer boroughs on Sunday, I want tunes galore. So I retrieved my 1996 Aiwa cassette deck, and, attic-bound as it had been for 20 years, it was in need of repair. Via Yelp, I came across Hi-Tech Electronics, a small repair-everything-electronic shop at the east end of Canal Street, in New York's Chinatown, and a mother lode of classic audio gear and audiophile nostalgia.
