I have long been aware of English audio company Prism Sound, both from my use at the turn of the century of their excellent PCI card–based DScope2 measurement system (footnote 1), and from some of my friends' enthusiasm for Prism's SADiE digital audio workstation. Prism Sound was founded in 1987 by two DSP engineers, Graham Boswell and Ian Dennis, who had first met when working at mixing-console manufacturer Rupert Neve, in Cambridge, England. From the beginning, Prism Sound operated exclusively in the world of professional audio, but a year or so ago I began seeing their first domestic audio product, the Callia, at audio shows.

"See her how she flies . . ." When I first heard that lyric, from Jim Webb's "The Moon Is a Harsh Mistress," sung by a hauntingly fragile woman's voice and supported by a sparse yet lyrical piano accompaniment, at an audio show in 1983, I got chills. Who was this empathetic singer? Back in my cabaret-musician days, more than four decades ago, I backed so many singers with beautiful-sounding pipes but who didn't seem to comprehend the meaning of the words—yet this unknown woman directly communicated the song's emotion.

In the first two parts of our video coverage of Jana Dagdagan's and my visit to PS Audio in Boulder, Colorado, we toured the factory and I interviewed the company's founder Paul McGowan. In this final video, I listen to three of my own recordings played on the legendary IRS V loudspeaker system, driven by PS Audio's BHK 300 monoblocks. I recorded the sound with Sennheiser's "Ambeo" binaural system, which mounts microphones on the outer surfaces of a pair of earbuds, and if you listen along on headphones, you will hear what I heard!

Earlier this week, we posted a video blog with PS Audio's founder and CEO Paul McGowan giving Jana Dagdagan and me a post-CES tour around the Boulder, Colorado company's factory. Following the tour, I sat down with Paul in Music Room One and in a wide-ranging conversation, we talked about amplifiers and loudspeakers, DACs and audio systems, and the state of high-end audio.

Immediately following the 2018 Consumer Electronics Show, our resident videographer Jana Dagdagan and I visited PS Audio in Boulder Colorado. The company's founder, Paul McGowan, gave up his Saturday to give us a tour of the factory.

MBL's Corona C15 monoblock has been one of my amplification references since I reviewed it in 2014, and as I've been reviewing DACs the past year or so, it was high time I spent time with one of the German company's digital products.

"Black shiny products are tough to photograph at shows, so trust me when I say the new N31 is dripping with gorgeousness not reflected in this photo," wrote Jon Iverson in his report from the 2017 Consumer Electronics Show. And when I unpacked my review sample of the Noble Line N31 ($15,400), I was indeed taken with its looks.

When Jason Victor Serinus visited the Bluebird Audio room on the Venetian's 35th floor, he mentioned that Chord was demonstrating its Blu Mk.2 CD transport ($11,788) along with the Dave DAC that I reviewed and was impressed by last June. I chatted with Chord's digital guru Robert Watts (above in photo) about the new transport and he mentioned that it incorporated his latest WTA (Watts Transient Aligned) digital filter with a million taps! (The more taps there are, the closer a DAC can reproduce the timing information in the reconstructed analog signal—see my DAVE review for why Robert feels why this should be so.) I was puzzled, as a digital reconstruction filter belongs in a DAC, not a transport.
