Your room is the most important part of your overall sound quality,” said Anthony Grimani of MSR Acoustics, who gave two well-attended lectures at T.H.E.Show showing how room acoustics problems can be tamed. “Come learn how to use absorption, diffusion, bass filters and traps to enhance your room’s acoustics and get the best from your system.”

Pride of place in the Avatar Acoustics room at the Venetian went to the four-way Siena speakers ($24,995/pair) from Italian manufacturer Rosso Fiorentino. The designer teaches electroacoustics in Florence, but is a graduate from the University of Salford in the UK. A pair of aluminum-cone 8" woofers in a separate sealed enclosure are combined with a 6.5" paper-cone midrange unit (a ScanSpeak Revelator), a 1" silk-dome tweeter, and what appeared to be a Murata "ultrasonic generator," to give a specified response of 35Hz–100kHz, –3dB.

The Siennas were demmed in a system comprising Dr. Feikert turntable and tonearm, Abbingdon Music Research CD player, phono preamp, and integrated amplifier, with Acoustic System racks and cables, but I will hand over to Jason Serinus for some additional thoughts:

Jason Serinus mentioned the Rosso Fiorentino Florentia loudspeakers ($99,995/pair) in his report on the Graaf amplifier in the Avatar Acoustics room below. This four-way speaker enclosure features aluminum front panels and glass side panels and weighs 361.5 lbs. The midrange and treble units are mounted in an open baffle, while the top-mounted woofer and the twin 12" subs are mounted in sealed enclosure. The subs are driven by a 1500W amplifier and the sensitivity is claimed to be 89dB.

When J. Gordon Holt founded Stereophile in 1962, it was very much the outsider. Compared with the mass-market magazine of which he had been Technical Editor, High Fidelity, Gordon's Stereophile was the very model of an "underground" publication, with a publication schedule as irregular as its production values were inconsistent. Its writing was from the heart, however.

Someone once said that if you build a better mousetrap, the world will beat a path to your door. Well, this month, we will see not one but two better mousetraps, in the form of Sony's and Philips' Super Audio CD and the DVD Forum's DVD-Audio. Both are intended to replace the humble CD, now in its seventeenth year; both offer higher-resolution digital audio; and both offer multiple channels. To accompany SACD, Sony's $5000 SCD-1 two-channel player is now on sale (and will be reviewed in the November Stereophile), while Panasonic has announced October sale dates for two DVD-A players, the $1000 Panasonic DVD-A7 and the $1200 Technics DVD-A10.

After hosting three hour-long seminars on Sunday (following five on Friday and Saturday), I spent the final hours of the 2007 RMAF racing around rooms I really wanted to hear before the Show closed at 4pm. At 4:30pm, I stopped by what would be my last room, the one featuring a new name to me, Salagar Speakers. This Illinois company is aiming high: its first product is a beautifully finished, physically large two-way active design, the Symphony S210, that combines a 1" soft-dome tweeter with a 10" woofer in an unusual curved enclosure. Power is provided by internal ICEpower class-D modules, and the integral X-ACT crossover operates in the digital domain and includes the facility to adjust the speaker's balance to cope with room acoustics problems. The Symphony S-210 costs $7,999/pair complete with crossover, and showed promise, even in the less-than-optimal hotel room.

Back in the day, you couldn't cruise the corridors at an audio Show without hearing Willie Nelson's arrangement of "Stardust" coming from every open door. So it was with a feeling of nostalgia that I walked into the Sanders room at Axpona and heard that familiar voice. Providing the tunes was an all-Sanders system featuring the Model 10c speakers ($13,000/pair including 500Wpc bass amplifier and crossover module), which combines an electrostatic panels for the midrange and highs with a transmission line-loaded 10" moving-coil woofer. Unusually, the active crossover operates in the digital domain, operating at 24/96 and splitting the signal at 172Hz with 48dB/octave slopes, which should ameliorate the problem blending the omnidirectional woofer with the dipolar panel. With a Sanders line stage, Sanders electrostatic amplifier ($4000), and Sanders cables—Roger Sanders feels strongly that a system should designed as a system—the 10cs sounded unexpectedly dynamic.

I had been looking forward to auditioning the 10th Anniversary Edition of Scaena's Silver Ghost speakers at the 2013 CES, but as I reported, there was a curious lack of recorded ambience. The Silver Ghosts, which cost $153,000/system with two active subwoofers, sounded much better at AXPONA, driven by Audio Research amplification. The front end was the new dCS Vivaldi rig and cabling was all Silversmith Audio Palladium. A duet between a woman singer and a double bass on the old Gloria Gaynor hit "I Will Survive" was absolutely convincing in its tonality and musicality—with plenty of recorded ambience!

Listening to Scaena's Silver Ghost speakers ($153,000/system) had been a highlight of last March's AXPONA in Chicago. At the Denver Tech Center Hyatt, the speakers had been set-up by Sunny Umrao (in photo) firing diagonally across a much larger room than in Chicago. With a system comprising a dCS Vivaldi digital source driving an Audio Research Reference 75 stereo amplifier for the towers and six inexpensive Crown class-D amplifiers for the six woofer modules operating below 120Hz, the sound of a live recording of Dave Brubeck's "Rondo a la Turk" did indeed sound live.

In their second room, Anaheim retailer Scott Walker Audio was showing Magico's Q3 floorstander ($38,950/pair) with the Soulution 700 monoblock amplifiers, hooked with Synergistic's cumbersome spaced-conductor speaker cable. Source was a Soulution 540 SACD player and a Soulution 700-series preamp. The Q3 was launched at the 2011 CES. A smaller derivative of the Q that Michael Fremer positively reviewed for Stereophile in November 2010, the Q3 uses the same proprietary beryllium-dome tweeter as the Q5 in the same type of space-frame enclosure, with a 6" Nano-tec midrange unit. The lower woofers roll off earlier than the upper one, to optimize the crossover to the midrange unit. Frequency response is specified as 20Hz–50kHz, sensitivity as 90dB, and impedance as 5 ohms.
