John Meyer's Newform Research's ribbon/cone hybrids have been around for a while, and, like Bruce Edgar's Edgarhorns, every revision I've heard sounded better than the previous one. The latest R645v3 has undergone some very significant changes: the midbass/bass box is now sealed rather than ported, with additional bracing and damping (Corian top), and the result is much-improved blending with the ribbon and greater transparency throughout the lower midrange. Sold factory direct, $3484 delivered makes the R645v3 an astonishing bargain in today's marketplace. The partnering electronics undoubtedly made a major contribution to the fine sound of the Newforms, and are interesting in their own right: they signal the return to the business of Richard Dolan, whose PM1 preamp was highly regarded in the 1990s. The Newforms were driven by Dolan Audio SMM-120 monoblocks (US$11,500/pair), with a prototype line stage (about US$7500), Shanling CD player source.

Bruce Edgar has been refining his Edgarhorn loudspeakers, available in kit form, for a good number of years now, and I've noticed a steady improvement in the sounds he's been getting at shows. The ones I heard at the Montreal Show were the best-sounding yet.

Lovers of Italian wine, travelers to Italy, and, of course, Italians, may be familiar with this story. It seems that in the year 1111, Henry V was traveling to Rome to be crowned Holy Roman Emperor. A member of his entourage, one Giovanni Defuc, was very fond of wine, and had the practice of sending ahead one of his servants to sample the wine in each place. When the servant found a wine that he particularly liked, he would write "Est!" on the door of the establishment, which was a signal to his master that the wine is (est) good. Having arrived at Montefiascone, the servant found a wine he thought so superb that he wrote on the door of the inn "Est! Est!! Est!!!"

PS Audio's first product, back in 1973, was a standalone phono stage; more recently, their PCA-2 preamp had an optional phono board. The GCC-100 integrated amplifier that I review this month has no room inside for a phono board, so they've gone back to producing a separate phono stage: the GCPH ($995). Like the other products in PS Audio's current line, this one is based on the Gain Cell, one module on the input side connecting to the cartridge, followed by a passive RIAA curve (with a claimed accuracy of 0.1dB over the 40dB range of the curve), and another Gain Cell on the output side.

Sonics is the name of a new line of speakers designed by Joachim Gerhard, the founder of Audio Physic, and imported by Allen Perkins (Immedia), formerly the US importer of Audio Physic. The top-of-the-line is the PassionS, a tall, striking-looking speaker that consists of angled modules, with each driver having its own enclosure. The price is $32,000. Allen obviously loves its sound!

I've always thought of Fujitsu-Ten as a company that manufactures car stereos. However, it turns out that they have a special division producing a line of home-audio speakers using single drivers of their own design. That's right: no woofer, no tweeter, no coaxially mounted woofer and tweeter—just a single cone driver, claimed to cover the range from 40Hz to 20kHz. In the top model, the TD712z ($7000/pair), this drive-unit is mounted in a rigid, egg-shaped enclosure. The sound of these speakers, driven by an Audion Sterling Plus Mk.II tube integrated amplifier ($2950), was simply stunning in its clarity and focus.

Audiopax, the Brazilian manufacturer of the Model 88 single-ended tube amplifier that I reviewed most favorably three years ago, introduced the Model 55 amplifier at T.H.E. Show. Solid-state rather than tubed, the 55 is still single-ended and still features the unique "Timbre Lock" control. According to designer Eduardo De Lima, this MosFET design sounds very close to the Model 88. Price is $11,990/pair (compared to the $14,990/pair of the current Model 88 Mk.II).

Hansen is a new line of ultra high-end speakers from Canada, using proprietary drivers and said to feature extremely dense, non-resonant enclosures. The company is headed by Lars Hansen, who, as former president of the Dahlquist Corporation, is no stranger to the world of high-end speakers. The sound of the Prince ($27,000/pair, third model from the top) was simply excellent—an auspicious debut, I felt.

Used by Bösendorfer in their demo, the Art Audio Adagio has to be one of the most beautiful tube amplifiers made. If you see it and don't want it, you have no soul.

Silverline Audio's new Prelude is a slim floorstander combining an aluminum-dome tweeter with two 3.5" aluminum/magnesium-alloy mid/woofers. Designer Alan Yun was running the speakers with a pair of Pass X600s (600Wpc), an unusual combination intended to show the speaker's potential for dynamics and bass extension—and it certainly did that. Nice, smooth sound, too. The Prelude seems like a real bargain at $1200/pair.
