There's a retro, Heathkit vibe to the curiously capitalized PrimaLuna ProLogue Eight CD player: a shelf of glowing tubes and a chunky transformer case perched atop a plain black chassis. But on closer inspection, it seems there's much more going on here. The chassis is made of heavy-gauge steel, with (according to the manual) a "five-coat, high-gloss, automotive finish," each coating hand-rubbed and -polished. The tube sockets are ceramic, the output jacks gold-plated. Inside, separate toroidal transformers power each channel. Custom-designed isolation transformers separate the analog and digital devices, to reduce noise. The power supply incorporates 11 separate regulation circuits. The output stage is dual-mono with zero feedback. Audio-handling chips include a Burr-Brown SRC4192 that upsamples "Red Book" data to 24-bit/192kHz, and one 24-bit Burr-Brown PCM1792 DAC per channel. Only the tiny silver control buttons (on the otherwise hefty faceplate of machined aluminum) betray a whiff of chintz.

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.

Chicago retailer Pro Musica, led by recording engineer Ken Christianson, had two rooms at AXPONA. The first featured a system built around Dynaudio's Confidence C2 Signature loudspeakers ($13,500/pair in standard Mk.II finishes; $15,000/pair in Signature finish). The electronics were a Naim NAP 300 amplifier with 300PS power supply ($11,495), Naim 282 preamp with NAPSC2 ($6795), Naim SuperCap2 DR preamp power supply ($6595), Naim UnityServe SSD server ($3045), Naim NDS streaming player ($10,995) with Naim 555PS DR power supply ($9645). Speaker cable was Naim NACA5 ($15/foot) and the equipment rack was the Quadraspire EVO (6 shelf, $1200).

When I first started buying records at the end of the 1950s, I had this vision of the typical recording engineer: A sound wizard wearing a white lab coat rather than a cloak festooned with Zodiacal symbols. He (it was always a "he," of course) would spare no effort, no expense to create a disc (LPs and 45s were all we had) that offered the highest possible sound quality. At that time I also believed that Elvis going into the Army meant the end of rock'n'roll, that my teachers knew everything, that politicians were honest, that socialism was the best form of government, and that talent and hard work were all you needed to be a success. Those ideas crashed and burned as I grew up, of course, but other than the long-discarded white coats, each new record I bought strengthened rather than weakened my image of the recording engineer.
