Audacious Audio

I have been an advocate of small speakers since I began using BBC LS3/5a's in the late 1970s, continuing through Celestion SL6es in 1981, Celestion SL600s and SL700s in the late '80s, and B&W Silver Signatures in the mid-'90s. Yes, I do like accurate and extended bass reproduction—but you need a big speaker to be able to provide that, and, as the late Spencer Hughes, founder of Spendor, once remarked, "big speakers have big problems." I don't see the point of extending a speaker's low-frequency performance if the result is compromised soundstaging and midrange reproduction. And there is also the intellectual elegance of a speaker that is no bigger than it need be.

The top-of-the-line model from America's leading headphone manufacturer, these are bulky, heavy, very business-like in appearance, and very, very good.

The ESP-9 is dual-powered: from the AC line, or from the input signal itself, The power supply is rather large and heavy, and appropriate in appearance to the phones. Amplifier connections are via wires with spade lugs attached, and speaker connections are made to the rear of the power supply. A front-panel switch selects speaker or headphone operation, and terminates the amplifier outputs with 10 ohms in the Phones position.

Construction is typically top-of-the-line Koss: Rugged, nicely finished, and apparently very durable, and the phones are easy to handle. (Many headphones are so loosely pivoted on their headbands that they swing into impossible positions whenever you pick them up.)

Simaudio saw disc-based digital audio in its rear-view mirror at least as far back as 2011, when it introduced the Moon Evolution 650D and 750D—two iterations of what it called a "digital-to-analog converter CD transport." These were actually multiple-input CD players, but Simaudio was evidently so eager to distance itself from the spinning disc that it went with a product category that, in spite of its cumbersome, run-on name, drew a clean line between the disc-reading and signal-processing functions—while bestowing upon the former second-class citizenship.

Life is too short to put up with poor-sounding headphones, I mused the other morning, during my 60-minute commute on the NYC subway. All around me, straphangers gripped smartphones and listened to multicolored Beats, noise-canceling Boses, white Apple earbuds, and, only rarely, Sennheisers and Grados.

"This is getting to be a habit."

That's how I ended the first paragraph of my review of Bowers & Wilkins' 800 Diamond speaker, in the May 2011 issue; apparently, Stereophile's habit of reviewing models from B&W's 800 series remains unbroken.

Later in that review, I said that "The 800 Diamond doesn't look radically different from its predecessors." That doesn't apply to the 802 D3 Diamond ($22,000/pair). It's still a three-way system with tapered-tube high-frequency and midrange enclosures, stacked and nestled into a generous bass enclosure that's vented on the bottom into the space between it and its plinth.

I still remember how difficult it was for me to transition from mass-market to high-end audio. The former, for all its flaws, gave me things to do: switches to flip, buttons to push, knobs to turn, meters to watch. I was in control—and if my attention happened to stray from the music or the liner notes, I still had something to keep me busy. By contrast, the first perfectionist-quality amplifier I bought—an Amber Series 70—was an oblong box with an on/off switch. Where's the fun in that?

Driving the Model Sevens at the 2014 CES were Vandersteen's then-new M7-HPA monoblocks, which provide a high-pass–filtered output (above 100Hz) to the upper-frequency drive-units of the Model Seven. At the time, I made a note to myself that I would like one day to try these amplifiers with the Sevens in my own room. That opportunity came later rather than sooner, after Vandersteen had updated the Model Seven to Mk.II status.
