Given that Quad's founder, the late Peter J. Walker, wasn't around to design the Quad II Classic Integrated, the English firm relied instead on Tim de Paravicini, whose credits include the comparatively recent Quad II-eighty mono amplifiers and QC-twentyfour preamplifier (not to mention his own line of E.A.R./Yoshino electronics and countless other well-regarded products). It's with respect for both men that I say: In turning to Tim de Paravicini, Quad has probably chosen the closest approach to the original.

"The realistic reproduction of orchestral music in an average room requires peak power capabilities of the order of 15 to 20W when the electro-acoustic transducer is a baffle-loaded moving-coil loudspeaker of normal efficiency." —Peter Walker and D.T.N. Williamson, writing in the Journal of the Audio Engineering Society in 1954

There's a nice symmetry in knowing that Liberty Audio Trading has been appointed the new Canadian distributor for Quad Electroacoustics: Years ago, Liberty's founder, the late Nizar Akhrass, was among the first to bring the line to North America. (Taiga LLC continues to represent Quad here in the States.) At SSI Liberty Audio demonstrated the entry-level Quad ESL-2805 ($10,000/pair). John Atkinson will be reviewing the ESL-2805 in the May issue of Stereophile.

Colleen Murphy, whose first serious system was built around a pair of Klipschorns, prefers vinyl to all other formats—not just for the superior sound, but for other, less tangible qualities. “It’s almost a ritual,” she said at NYAS 2013. “The inconvenience is one of the things that makes us give ourselves over to it.”

I thought the Raidho D-1 loudspeaker ($28,000/pair, including stands), was among the most interesting and musically impressive new products at SSI. Raidho, a Danish company known for their work with ultra-lightweight ceramics, has developed a process for bonding to their speaker diaphragms a thin coat of industrial diamond, conferring even greater stiffness and freedom from unwanted resonances. Paired with a Jeff Rowland Aeris D/A converter and Jeff Rowland 625 power amplifier, the Raidhos were impressive on a variety of material. We’ve all heard demonstrations where we came away saying, “I can’t believe they got so much bass out of such little loudspeakers,” but in terms of the sheer quality and scale of that bass, the Raidho/Rowland combination was on another plane altogether.

In one of the rooms sponsored by Audio Pathways, the always-impressive yet consistently difficult-to-photograph-in-the-dark Raidho Acoustics C1.1 loudspeakers ($CAD18,000/pair) sounded excellent with a slightly-less-photo-phobic Jeff Rowland Continuum S2 integrated amp ($10,500), set up with Transparent cabling.

No one can say precisely how or when the ancient 300B triode tube made its cross-kingdom leap to the modern world of consumer audio, but we've got the where pretty much nailed down: It all began in Asia, where the best of the West is sometimes held in reverence rather than left to drown in consumerism's wake. Asia is the final resting place for the great Western Electric cinema systems of the 1940s—and that's where the 300B earned its un-American second act. By the mid-1990s, the tube had captured the hearts of hobbyists who, consciously or not, sensed that the audio refineries of the day had lost the plot, not to mention the body.

Granted, I know little to nothing about the home theater market, but I thought this was kind of cool: a paint called Screen Goo, available through all Sherwin-Williams dealers, that can be used to transform any flat, paintable surface into a projection screen. This two-stage treatment—a reflective undercoat, topped with a semi-translucent diffusive top coat—is 100% acrylic, with a very low VOC content. Screen Goo is available with different degrees of pigmentation; the photo above compares unity-gain white, on the far right, with two other shades. This company’s biggest market? According to Kevin Nute of Goo Systems, it’s theme-park installations (eg, the Haunted Mansion at Disney World).

Seen on static display in the Canadian Pavilion at SSI: the 2A3-S single-ended amplifier from Triode Lab ($3288: an exceptionally good buy, assuming this nicely built amp sounds as good as it looks).

Red Wine Audio of Holden, MA, was the remaining link in the Sound by Singer chain: The aforementioned Bricasti D/A converter was, by means of its own volume control, used to directly drive a pair of Red Wine Liliana monoblock amplifiers ($5995/pair), wherein class-A tubed input stages are mated with class-A/B FET output stages to produce 115Wpc of very sweet-sounding watts. In this pic, Red Wine CEO Vinnie Rossi shows off the innards of his Isabella preamplifier ($3995 without phono-stage option), which uses 6H30 "super tubes," yet also supports all triodes in the 6922 family.
