Pro-Ject Pre Box S2 Digital D/A headphone amplifier
I first met Pro-Ject Audio Systems' founder and president, Heinz Lichtenegger, in 2016, at the US launch of the Austrian company's The Classic turntable. His passion for all things hi-fi was so intense I thought his head might explode. Gleeful in his mission to bring high-end audio to the people at less than typical high-end prices, Lichtenegger and Pro-Ject can fairly claim bragging rights for their entry-level Debut Carbon (DC) ($460 and up), one of the world's best-selling turntables.
PS Audio Digital Link II D/A processor
Looking at the Digital Link II's build quality and circuitry, it's hard to believe that it can sell for $499 at retail. The Digital Link II shares the same appearance as PS Audio's SuperLink and UltraLink processors, but has a 4"-shorter chassis. The ¼"-thick front panel uses PS Audio's familiar touch-sensitive switches that turn the unit on and select between coaxial and optical inputs. LEDs above these switches indicate when the unit is locked to the digital source. A third LED illuminates when power is applied.
PS Audio NuWave DSD D/A processor
Researchers at MIT recently discovered a "music channel" in the human brain. These neural pathways respond to all kinds of musicand only to music. "A listener may relish the sampled genre or revile it," Natalie Angier wrote in the New York Times. "No matter. When a musical passage is played, a distinct set of neurons tucked inside a furrow of a listener's auditory cortex will fire in response"
PS Audio PerfectWave DirectStream D/A processor
It's like hearing the name of an old friend and then seeing him, in your mind's eye, as he was when you were both much younger: Whenever talk turns to Boulder, Coloradobased PS Audio, I can't help picturing that company's Model IV preamplifier, of the early 1980smost likely because that was the preamp I longed to own at the time. (Tragically, I couldn't afford to buy it, so I struggled on with my NAD 1020.)
PS Audio PerfectWave DirectStream MK2 D/A processor
When Art Dudley reviewed the original PS Audio PerfectWave DirectStream D/A processor in Stereophile's September 2014 issue, he very much liked what he heard. "For those who've waited for a computer-friendly DAC that offers, with every type of music file, the best musicality of which DSD is capable, the PerfectWave DirectStream may be in a class by itself," he concluded. It was computer-friendly because, with an add-in card, you could connect it with USB or to an Ethernet cable and use it with, for example, Roon or JRiver.
PS Audio discontinued the original DirectStream DAC in 2022, introducing its replacement, the DirectStream MK2, priced at $7999, in January 2023. At 17" × 4" × 14", the MK2 is the same size as its predecessor, and with its gloss-black MDF top panel, it looks very similar.
PS Audio UltraLink D/A processor
The night before I started to write this review, PBS began a five-part series on computers called "The Machine that Changed the World." The first episode described the development of the ENIAC (Electronic Numerical Integrator and Accumulator), the first electronic computer. The ENIAC used 18,000 vacuum tubes, had over 500,000 solder joints, required a room 30' by 50', had to be physically reprogrammed with patch cords to perform different tasks, and packed less computing power than today's $4.99 pocket calculator.
PS Audio UltraLink Two digital processor
Of all the products I've reviewed or auditioned, a select few jump out as "best buy" recommendations. Almost universally, such products are liked by a wide range of audiophiles, and seem to match well sonically to many systems. Moreover, these products all have outstanding value; they offer a higher level of musical performance than you'd expect from the price.
Rega DAC D/A processor
"We like to make things," Roy Gandy, Rega's founder and owner, once told me. "It's what we do." Or maybe it was Rega's chairman and chief engineering honcho, Terry Bateman. Rega products are designed and manufactured in the south of England. So far as I know, no one at the Rega facility, on the Temple Farm Industrial Estate, has committed suicide; the same cannot be said of workers at the factory in China where iPods are made. Al Gore is on the board of Apple. Al, what do you think?
Rega Research DAC-R D/A processor
I've spent the last month recording songs for a pal's upcoming album. His act consists of powerful female and male singers, acoustic and electric bass, and acoustic guitars and mandolin. Jay-Z is funding the project, which is destined to transform the entire hip-hop/rap beat-driven pop landscape into an acoustic-music wonderland.
Okay, I jest about that last part.
Resolution Audio Cantata Music Center
The dual subwoofers were bumping and our pant legs were flapping. Only moments before, we'd been treated to a polite viola da gamba. Not now. Resolution Audio's designer, Jeff Kalt, had brought only two discs with him to ensure that his company's Cantata Music Center was functioning properly in my system: Jordi Savall and Hespérion XXI's Altre Follie, 15001750 (CD, Alia Vox 9844), and Tool's 10,000 Days (CD, Tool Dissectional/Volcano 81991). After changing a few things around with the chamber music, we'd advanced to the hard rock of Tool.
