One of my formative audiophile experiences was the first time I heard electrostatic speakers. I walked into an audio store and heard music played by a live jazz combo. But where were the musicians? I saw none, though I did notice a couple of room-divider panels in the part of the store where the music seemed to be coming from. Eventually, it dawned on me that these must be loudspeakers—but they sounded like no other speakers I'd ever heard, and nothing like the Advents I had at home.

Taking a photo of a single speaker for a show report presents a challenge, especially if the speaker is narrow and tall. In the case of the new MartinLogan EM-ESL X, the flagship of the ElectroMotion series (at $3995/pair, I make it close enough to $4000 be part of my territory), I solved the problem by enlisting the help of the uncommonly photogenic Erin Phillips, Communications Manager for MartinLogan and Paradigm.

When it comes to directivity in loudspeaker frequency response, the trend has been to make them less directional, both vertically and horizontally, so that the speakers would be less sensitive to seating position and allow more then one person to enjoy the same tonal balance. The new Copernicus II ($21,000/pair with powered subwoofers and digital equalization/phase correction) from Alltronics Technical Systems takes the opposite approach, going for maximum directionality/focus. The drivers form a vertical line source with a concave curve, the speakers being "aimed" at a seated listener. Not only that, but there's a motorized control moving the speaker up and down to match the exact height of the listener's ears when seated. These are what I'd call "bachelor’s speakers!" They are certainly not designed for listening by couples, but the upside is the the soundstage can be extremely precise and three-dimensional, and the sound itself was well-balanced and dynamic. Here’s designer Dennis Althar with his baby.

Barrie, Ontario, about an hour's drive from Toronto, with a population of about 130, 000, is not a city that I associate with the design and manufacture of high performance audio equipment. It doesn't have even a single "real" audio store, just Best Buy, etc. But, as I found out at SSI 2010, Barrie is the home of McAlister Audio, maker of the OTL-195 monoblock amplifier and a prototype preamp. The designer is Peter McAlister, who produced his first prototype output-transformerless power amp ten years ago. The OTL-195 puts out 150W, and appears to be a very sophisticated design: fully balanced, able to drive 4 ohm loads, a circuit that tracks the signal level in the driver stage and modulates the control grids of output tubes, and various other circuit refinements. The OTL-195 is hand-built by Peter McAlister himself, and utilizes high-quality parts. The price is $8500/pair. As I mentioned in the blog posting below, the King Sound Prince IIs sounded great driven the McAlister OTL-195s.

It began when I reviewed the MartinLogan Montis loudspeaker (September 2012). The amplifiers I had to drive the pair of them were the PrimaLuna ProLogue Premier integrated ($2999), the Audiopax Mk.II (no longer available; the Mk.III costs $22,000), and the Simaudio Moon Evolution W-7 ($9000). The first two are tubed, with power in the 30–40Wpc range; the solid-state Simaudio puts out 150Wpc. The Audiopax, which sounds great with my Avantgarde Uno Nanos, turned out to be not such a good match for the Montises: weak in dynamics, and too soft sounding. The PrimaLuna and the Simaudio were better overall, each with its strengths and weaknesses, though neither was ideal. I really liked the ProLogue Premier's tonal characteristics, and wondered what a higher-powered tube amp would sound like with the MartinLogans.

I know of speakers where, depending on the crossover, the same 5" or 6" driver is used as midrange or as woofer, but I've never encountered a speaker where a driver normally designated as a tweeter also functions as a midrange. This is the unusual design approach taken by McIntosh in some new speaker models, including the $10,000/pair XR100, and, judging by the sound, it certainly works for them. The driver is a 2" metal dome: eight of these are combined to serve as midrange, with two more as the tweeter flanking a supertweeter.

Turntables were very much in evidence at FSI, some being on demo by their distributors, and some being used by exhibitors who just wanted people to hear what their speakers/amps/preamps sound like with a good vinyl source. Perhaps the most interesting turntable demo that was of the venerable Linn Sondek LP12, which is the turntable that I own. Linn has recently announced a series of upgrades they say make a major improvement in the sound of the LP12. Not content merely to make promises, Linn had a comparison of two versions of the LP12 and its matching arm, one that was current as of a couple of years ago, and another that had the new SE upgrades installed, both with the same cartridge, both optimally set up by Linn setup expert Gary Dilliott (who had set up my own LP12 a few years ago). I didn't have time to listen closely to the comparison, but I overheard at least one Linn owner in the room exclaim that he wouldn't have believed that such an improvement was possible. Looks like my LP12 is due for a trip to the shop. Pictured with the two Linns is Gary Dilliott. Can you tell which turntable is the upgraded version?

People whose memories go back a long way may remember Dick Sequerra’s highly-regarded Metronome Seven loudspeakers. They haven't been made for some years, but the importers of Thorens products have prevailed on Dick Sequerra to start making them, and a pair of these (serial No.3) was being used in a system that included a Thorens turntable (natch), Ron Sutherland’s PhD phono stage and Direct Line Stage, and new $15,000/pair Thorens monoblocks. The speakers are designated Metronome 7.7 Mk.6, and are priced at $1995/pair. Very nice sound, especially considering the fact that the system was in one of the Venetian rooms with ceilings that are much higher than any normal home. Here are Ron Sutherland and Thorens importer Chuck Kennedy, kneeling at the altar of High Fidelity.

The ever-enthusiastic Mike Tang, of Mike Tang Audio, had a system to warm the hearts of anachrophiles: Thorens TD124 with custom tonearm to match the Decca cartridge, Meridian MCD CD player (no modifications), Marantz 7C tube preamp, with the new parts of the system consisting of a Feastrex CV4055 power amp (8W, $5500), and Feastrex NF5 driver ($4500/pair, $7000 installed in a custom cabinet.
