Sure, everybody knows Ludwig van Beethoven. But how about his slightly less famous baroque predecessor (Johann) Ludwig Krebs?

Cheap for high end—but not cheap

THE VERDICT
A superb loudspeaker system from top to bottom—surely one of the best affordable high-end options available.

When you hook up a PSB speaker—pretty much any PSB speaker—you have a very good idea of what you’re going to get. To wit: balanced octave-to-octave response that fits a tight decibel window from the design’s lower limit to its upper; off-axis curves that are similarly smooth and “well bundled,” rolling off higher frequencies progressively at more extreme angles but without sudden discontinuities; impressive-for-size low-end extension without any enhanced, bass-sweetening pre-rolloff response hump; a reasonably unchallenging impedance curve for easy-to-drive amp-friendliness, and coherent, strong stereo imaging promulgated by carefully derived driver locations and spacings and by a diffraction-free cabinet design.

THE VERDICT
These compact, versatile, and affordable combos will drive good bookshelf speakers or headphones to audiophile heights, each with its own sense of style.

It’s certainly a thing. It may be a trend. Or possibly even a wave—a new-wave, high-res groundswell sweeping over the nation’s small but growing (we hope!) cadre of youthful audio fans.

I’m talking about ultra-compact integrated-amplifier/digital-to-analog converters: “ampDACs,” I’m calling them. The newly evolved species combines a two-channel integrated amplifier (usually of modest power), a headphone output (usually), and high-resolution audio digital-to-analog conversion, all engineered to meet audiophile expectations of quality, and all packaged into a single, paperback-sized unit conceived for versatility. (Most models, including the two under review here, add today’s ubiquitous Bluetooth wireless capability.)

Minus

Requires personal computer for setup; no onboard auto calibration

THE VERDICT
A noteworthy addition to the high-end preamp/processor ranks, with Dirac Live a fascinating, must-hear plus.

Talar du svenska? Emotiva does. Enough Swedish, at any rate, for the Tennessee tenderer of direct-to-consumer A/V gear to bake Swedish firm Dirac’s speaker/room-correction DSP into its new preamp/processor, the long-awaited XMC-1.

If you’ll forgive a Miller analogy, Dirac is to Uppsala University as Audyssey is to USC: Dirac, too, evolved out of original academic electroacoustics research—although USC’s weather is better, and I’m pretty sure the Trojans could take the Swedes on the gridiron.

It’s a self-administered “quiz” on file-format and audio quality, with six music segments presented, each with three clickable, on-screen “Play” buttons…

How high is high-resolution? How stereo is stereo? How many bits are really dancing around inside your DAC?

Remember radio? You turned it on, tuned it in, and got music, for free. (Well, free-ish; of course there were ads.)

Limited system control features

THE VERDICT
The SD-WH1000U is beautifully built and an outstanding A/V performer wired or wireless, but it’s not quite up to service as a full-system hub controller.

Trundle down to your local big-box store, and you will find quite literally dozens of Blu-ray Disc players on offer, starting well under $50. Big ones, little ones, skinny ones, flat ones, cheap ones, and cheaper ones.

None of these will be Sharp’s new SD-WH1000U, a Blu-ray player with a difference. Two differences, in fact: First, it has a jaw-slackening price tag of $5,000; second, Sharp’s design is wireless-centric, being the first WiSA-compatible player to appear, and one of the very first WiSA sources of any description.
