I went into the SimpliFi room expecting to see the excellent Weiss MAN301 media player and effective DSPeaker room correction and D/A devices. Yes, there were there at RMAF but SimpliFi's Tim Ryan wanted to talk about the Swiss Klangwerk Ella active speaker ($15,000/pair) shown in my photo. This modest-looking floorstander uses DSP to make it work as a time-aligned virtual point source. A constrained layer-damped Corian front baffle supports an advanced Aerogel-dome tweeter from Audax and a 5.5" woofer; two more 5.5" woofers covering the same passband are placed on the speaker's sides, and all three are reflex-loaded with a downward-firing port. The advantage of this design is that it has a wide listening window on both vertical and horizontal planes, explained Tim, and indeed, on Dire Straits' "Brothers in Arms," I found that I could move up and down and from side to side without any significant change in the perceived balance.

Listening to a Toni Braxton cut on the LSA1 Statement speakers ($2599/pair), driven by an Exemplar-modded Denon 2910 DVD player and LSA's hybrid integrated amplifier (reviewed by Stereophile when it was called the DK Designs VS.1 Reference Mk.III), I was struck by how much low-frequency information was coming from this nicely finished two-way stand-mount.

When someone is described as having "written the book" on a subject, it is generally taken as a figure of speech. But veteran speaker designer Joseph D'Appolito, PhD, quite literally "wrote the book." His Testing Loudspeakers (Audio Amateur Press, 1998) is an invaluable resource for those of us who, lacking any talent for designing speakers ourselves, nevertheless find the subject of speaker performance endlessly fascinating. So when Snell's PR consultant, Bryan Stanton, contacted me a while back about reviewing the LCR7, the first design D'Appolito had seen through from start to finish for the Massachusetts-based company since he had replaced David Smith as Snell's chief engineer, I suffered from more than a little anxiety.

SSI seems to feature a higher proportion than usual of rooms sponsored by high-end dealers, and one of the best sounds I experienced was in the room from Montreal dealer Son-Or Filtronique. The top-line, multi-box dCS Scarlatti SACD front-end (soon to be reviewed for Stereophile by Mikey Fremer) drove Audio Research electronics (Reference 3 preamp and Reference 110 amplifier) with speakers the impressive Kliimt from Vienna Acoustics. Cabling was all Shunyata. Corinne Bailey Rae's perfomance of Joni Mitchell's "River," from the Herbie Hancock CD of the same name, was reproduced with midrange to die for, though the low frequencies were a touch over-ripe, I thought.
