...and 3.6kW into 2 ohms! All in a day's work for Krell's $40,000/pair, Krell Evolution 900 monoblock amplifier. On passive display with its top off, you can see that the amplifier has three output modules, each containing a pair of driver stages, 28 bipolar output devices, and a massive heatsink that vents heat in chimney fashion through vents in the top and bottom of the chassis. The power supply features two 3kVA toroidal transformers, 52 electrolytic capacitors, each rated at 1800µF, 900watt, and 105°F. Weight? Again I didn't want to know, but was told it was a mere 175 lbs!
HE 2007 had, as expected, some very expensive equipment being demonstrated, but there were also some modest-priced and still very–good-sounding systems. One of these was the system in the DCM room, based on the DCM TFE 200, a substantial floor-standing speaker priced at just $1000/pair. With a Jolida CD player and integrated amp, the total price for the system was under $3000—and that was including $200's worth of cables from Esoteric Audio. The Man in Black is Al Congdon of DCM.
Remember the name: Salagar Sonics. It's the name of a new American speaker company, whose first product, the Salagar S210 ($7500/pair), still in prototype form, made a strong impression at HE 2007. It's an active two-way—digital crossover; the amp uses the latest B&O ICE module—with a Scanspeak AirCirc tweeter and a 10" Peerless VIFA mid-bass driver, in an unusually-shaped (and highly inert) enclosure. I thought these speakers sounded terrific: lively, low in coloration, and with excellent imaging.
Late Sunday afternoon, with only about an hour left before the show closed, it was still standing room only in the Music Hall room. Perhaps that had something to do with the choice of music. I walked in to be greeted by the naughty sounds of the Bear Family Records compilation, Eat to the Beat: the dirtiest of them dirty blues, featuring song titles I can't even mention here.
Masataka Tsuda designs and manufactures both Concert Fidelity and Silicon Arts components. What's the diff? Concert Fidelity is his tube line; Silicon Arts Design represents his thinking on—you guessed it—solid-state.
The Audioengine team is also looking at alternative cabinet materials. On display was a prototype A5 housed in lovely, sustainable bamboo. While the electronics remain the same, the bamboo models will incorporate added dampening.
Krell Industries' new Modulare Duo loudspeaker system was the one active exhibit in their suite, playing music from an excellent sampler of audiophile favorites. Todd Eichenbaum, shown standing next to the $35,000/pair, 300 lb system, explained that the separate woofer and satellite units were made of machined billet aluminum, as with Krell's original LAT-1 speaker system, but the Modulare’s drivers and passive crossover circuitry have been designed for higher current handling. The low-frequency cabinet contains three 8" aluminum-cone woofers, while the satellite section marries a 1" ScanSpeak ring-radiator tweeter, and a 6.5" aluminum-cone midrange driver.
We trucked across the hall to the treated room which contained several sets of RPG Variscreen free-standing variable acoustics screen ($700/each), a Modex Plate ($1000)—which offers broadband low frequency absorbtion from 50–500Hz—and two Rives Audio Sub-PARC crossover/EQs ($4500/each). The system also boasted an extra pair of VAC Alphas—Richard Rives explained that he was using the Sub-PARCs as crossovers, bypassing their digital woofer amps to kep the signals equivalent from top to bottom.
Indeed, there were nice things from Sweden in the Sjofn HiFi room. I didn't get a taste of the snittar (Swedish finger sandwiches), but I was very impressed by the powerful bass and deep, wide soundstage created by the diminutive Guru loudspeakers. As Wes mentioned, the Gurus were designed with the room in mind, and are meant to be placed near room boundaries.
I never miss the John Atkinson Trio's performances. I like to watch my friends play music and it's a great chance to bond with my fellow audiophiles for an hour or so. But this year wasn't like other years—the boys just flat-out smoked! Allen Perkins of Immedia, already one of my favorite drummers, has been studying with Peter Erskine for a few years and he has burned away any clutter (not that there was much) and is now even more purely him than ever. Bob Reina's regular gigging with Attention Screen has focused his strengths and, I suspect, freed him from having to express everything he has to say every time out. He's playing freer, looser, and tighter than ever. And JA (photographed here by Bob Deutsch), I suspect he's been woodshedding. With editing Stereophile, producing records, and measuring every component we review, where does he find the time?
