The Pathos InPower monoblock amplifier ($13,500/pair) is a hybrid design offering 80W (at 0.4% THD, 5Hz–60kHz, ±3dB. It features some of the most beautiful industrial design I saw at the show. Designer Gianni Borinato describes it as a balanced, double INPOL power amplifier, with a zero-feedback, hand-matched. MOSFET output stage biased to run in class-A. The point-to-point wiring uses silver wire. Two triode tubes in the input stage are wired in opposite phase to form a double triode that is claimed to minimize distortion. The design proved its merit by driving the Focal 1037 Be loudspeakers with speed, dynamics, and excellent imaging. The room was a favorite among the Stereophile writers at the Show.

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.

Todd Eichenbaum, design engineer at Krell, walked me through the design of their new amplifier, the $10,500, 300Wpc 302. The power supply employs a 3kVA toroidal transformer, built-in power conditioning, a current-mirror input stage, a push-pull driver stage, and low negative feedback (8dB) around the output stage. It was paired with the $10,000 Evolution 222 stereo preamplifier.

My interest in wireless network music players began during David Hyman's keynote speech at Home Entertainment 2003. Then CEO of Gracenote, Inc. (footnote 1), Hyman stunned me with his opinion that CDs and DVDs were already obsolete. Rather than pursue discs with greater storage capacity, Hyman urged industry designers to design music-server units with large hard drives to allow instantaneous access to any digital music track. With all of your music stored on a central hard drive, you could, within seconds, locate a specific track among thousands just by knowing the name of the artist, song, group, composer, year of recording, or even recording venue. Music mixes could be instantly grouped into playlists by the owner.

AIX Records' Mark Waldrep, see here with Mona Waldrep, was promoting their latest DVD-Video and DVD-Audio, surround-sound release, Ernest Ranglin, Order of Distinction. Featured performers included Robbie Krieger from the Doors, Phil Chen and Laurence Juber from Paul McCartney's Wings group, and Elan Atias from the Caars. Mark reminded me that his website, Itrax.com, will go operational in June, providing one of the only sites where high-quality, lossless-compressed, surround-sound music files will be available for purchase and downloading.

"Now that's real room lock," I exclaimed, listening to the deep pedal organ notes from John Mark’s recording of James Bustard playing Herbert Howell’s Master Tallis’ Testament, recorded at the Church of St. Stevens in Providence, Rhode Island. Tierry Budge's new loudspeaker, the floorstanding, two-way, Pearlized White, $18,990/pair speaker played the pipe organ pedal chords with thunder and power when driven by the VTL S-400 amplifier and the new dCS digital front-end on one of the Sound By Singer rooms. The speaker's large enclosure holds both an external 12" woofer and an internal 12" driver, which allows Budge to rate the speaker's response down to an impressive 18Hz. Budge claims the internal 12" minimizes group delay, reducing the driver's rise time from its nominal 500ms to 55ms. The tweeter is soft-dome, ring radiator made by Scan Speak.

Andrew Watson proudly discussed the latest iteration of KEF's reference floorstanding speaker, the $20,000/pair 207 Mark 2. This new version features a new UNI-Q array that no longer needs the hypertweeter found in the Mark 1 version. The new tweeter has a vented magnetic assembly to provide more air volume behind the dome to smooth the sonic response. The manufacturer has to drill through the magnet assembly, thereby reducing its sensitivity. As a result, two additional neodymium rings were added to the usal magnet. The new tweeter's design has the voice-coil former touching the dome at two points to lend additional support and prevent breakup at high frequencies.

Krell’s new Krell IPOD Dock (KID) only costs $1200, but offers balanced outputs, signal conditioning with bass and treble adjustments, all digital control lines, diverse outputs (2 balanced, 2 RCA, and S Video) with optical isolation. The auxillary input allows one to attach a Zune or Creative Digital Zen MP3 player. The Krell KID received much attention from press and public alike.

A tradition at HE SHows is the "bazaar: in one of the hotel's ballrooms, where record companies and accessory manufacturers do a brisk business. Here, Marcia Martin of Reference Recordings shows off their latest release Serenade, a recording of the same vocal group, the Turtle Creek Chorale, as in their best-selling Rutter's Requiem CD.

On January 1, 1990, Canadian electronics manufacturer Bryston instituted a remarkable warranty program that covered each of their products for a full 20 years. This warranty includes all audio products ever manufactured and sold under the Bryston name. Besides covering parts and labor costs, the company will also pay shipping costs one way. This is all the more significant for their 4B NRB amplifier, which has been in production since 1976. The amp's $2k price, while not cheap, is at the lower end of what well-heeled audiophiles typically pay for amplifiers.
