While visiting Gradient’s North American distributor, Simplifi, I listened to the current version of their classic Revolution loudspeaker ($7995), which had been favorably reviewed in Stereophile back in 1995. Earlier in the show I’d been impressed with the uncanny spatial realism in the MBL room; the interestingly shaped, dipolar Gradient Revolution was at least its equal in that regard. On one record, singer Willie Nelson was right damn there, and when someone in his band started giving hell to a tambourine, the effect was almost nerve-rattlingly real. What a cool speaker!

In the early to mid-1980s, I read every high-end hi-fi magazine I could get my hands on. Among the consequences was my discovery that the Grado Signature Seven phono cartridge—which was better and cheaper than the Signatures One through Six—was the cartridge that God wanted me to have. So I cut back on all manner of luxuries, saved every dollar I could save, and a few months later brought a walletful of cash to Harvey Sound in midtown Manhattan, where an unpleasant man with a bad comb-over handed me a little pill bottle of a plastic tube.

The best tonearm I ever heard was a second-generation Mission Mechanic, ca 1986. It was mounted on a Roksan Xerxes turntable, and I spent several happy hours listening to records on that combination (with a low-compliance EMT cartridge) in two very different systems: one with solid-state amplification from DNM and Roksan's own dynamic Darius loudspeakers, and the other—my home system of the time—using tube amplification from Conrad-Johnson and a borrowed pair of Stax electrostatic speakers.

Near-holographic imaging—an audio ideal for some hobbyists!—could be heard in the Nola suite, where the company's new KO loudspeaker ($9800/pair) was demonstrated with Audio Research amplification, Audio Research CD player, and Nordost cabling and Quantum QX4 EMF-control devices. The 3.5-way KO uses aluminum-cone woofers and is described by designer Carl Marchisotto as offering 90dB sensitivity and a nominal 8-ohm load.

The record player used in the Robyatt suite was the Anatase (price available upon request) from Oswalds Mill Audio: an original Lenco motor unit updated with a custom-made bearing and idler wheel assembly, and wedded to a massive slate plinth. The primary arm was the excellent Thomas Schick Tonearm ($1675), used with various Miyajima cartridges.

I kept seeing pictures of something that looked a little like a DeVore O/96 and not really knowing what it was. Now, thanks to the GTT Audio room at SSI, I know that the thing I was seeing is the Grimm Audio LS1-S ($39,900), a three-way powered loudspeaker pair plus digital preamp with USB interface.

I’m not familiar with Raysonic, but their system sounded excellent: a large-scale presentation with good color and texture, elements of which may have been owing to the impressive-looking Raysonic Reference 26 mono tube amplifiers ($16,500/pair in Canadian funds). Each 180Wpc amp contains 12 Russian-made 7591AEH output tetrodes, configured for true balanced operation. (We were told that the loudspeakers, which bore the name Revolver, aren’t commercially affiliated with Raysonic.)

Stereophile alumnus and publicist extraordinaire Jonathan Scull—Bel Canto, Furutech ADL, DEQX, XLO—exchanges fire with the RMAF registration staff: In life as in the Leonard Cohen songbook, "Outdrew ya'" rhymes with "Hallelujah."

Within a few years of entering the US market, Australian audio manufacturer Bruce Halcro Candy cemented his place in audio history by designing a amplifier that Paul Bolin said (in the October 2002 Stereophile) "could well justify the creation of a 'Class A+' amplifier category in 'Recommended Components'," and the low distortion characteristics of which prompted editor John Atkinson, a man who has elevated the craft of understatement to a high art, to reach for the word astonishing. That was the Halcro dm58 monoblock ($29,990/pair), which has only recently been superseded by the Halcro dm78.

I remember being impressed when I looked inside my low-impedance Miyabi 47 phono cartridge and counted approximately 14 turns of wire per channel on its coil former. Haniwa has now produced a cartridge with an even lower number of turns per channel—two!—for an internal impedance of just 0.8 ohms. Nevertheless, Haniwa has used various materials and construction techniques to maintain a quite reasonable output of 0.35mV. The Haniwa HCTR01 cartridge, which is also a notably high-compliance design, is available for $12,000. Michael Fremer reviewed it in his November 2011 “Analog Corner” column.
