LATEST ADDITIONS

Meridian pioneered the integration of digital crossovers and D/A converters in a powered loudspeaker and the first room I visited at the 2013 CES featured the DSP7200 speaker ($38,000/pair). The has anew tweeter, said to be smoother and more open-sounding than the HF units used in earlier speakers, but perhaps more importantly, the 7200's crossover now compensates for the low-frequency group delay associated with the high-order alignment. This is difficult to do, as it conventionally demands a very long digital, computationally intense filter. However, Meridian's engineering team came up with a solution that only adds around 40 milliseconds of latency. While this might make video synchronization tricky, the added clarity at low frequencies was impressively audible. Bass started and stopped as it should, with none of the feeling of the lows being detached from the upper ranges that is typical of high-order woofer alignments.

Jeff Joseph was demming his new Pearl3 floorstanding speakers ($28,100/pair) in an all Bel Canto system (including their new USB converters), hooked up with Cardas cables. Jeff's music choice was decidedly idiosyncratic— a duet for marimba and double bass, a recording of an African singer and sax player made in his backyard, Harry Belafonte live at Carnegie Hall—but with every kind of music, the Pearls allowed the music to speak most effectively.

"The synergy is palpable between Triode Corporation's Japanese-made electronics and Acoustic Zen's loudspeakers and cables," wrote Jason Serinus earlier in this blog and I just wanted to add my 2 cents. As I had in many rooms at CES, I auditioned my recording of pianist Hyperion Knight performing Gershwin on the Acoustic Zen Crescendo speakers ($16,000/pair). The sound of the Steinway was sweet—perhaps a little too sweet?—and the soundstage was wide, deep, and stable.

Larry Greenhill, who was covering expensive amplification at CES for Stereophile already blogged about the Constellation preamp and power amplifiers that were being used to bi-amp Magico's top-of-the-line Q7 loudspeakers ($185,000/pair). But here's a photo of the speaker, which was connected with MIT cables. AC conditioning was courtesy of Shunyata, racks by HRS. The sound in this room was magnificent, whether it was Lyle Lovett's "The Boys from North Dakota," Leonard Cohen's 10 New Songs, or my own live recording of Cantus performing Curtis Mayfield's "It's Alright." Oh my!

At every CES, I seem to find out on the last day that there was something I should have checked out. And, sure enough, on Friday afternoon, I’m talking to Wayne Schuurman of the Audio Advisor, who mentions that Magico has a new speaker that’s about $13,000/pair.

T+A (Theory and Application) is a German audio company best known in North America for their electronics and source components, not their speakers. That’s about to change with the appointment of Dynaudio as T+A’s North American distributor, and the introduction of the T+A Criterion line of loudspeakers. Asked whether Dynaudio—which, of course, is a loudspeaker manufacturer—has collaborated with T+A on the design and/or manufacturing of their speakers, Dynaudio’s Mike Manousselis quickly assured me that Dynaudio functions only as the distributor for T+A; the T+A speakers are manufactured entirely in the T+A factory in Herford, Germany. Dynaudio makes loudspeaker drivers that are used by quite a few speaker manufacturers, but T+A is not among them.

Although a number of speaker manufacturers use Heil AMT drivers, only one company has the rights to use the name of the original speaker company that used Heil drivers: ESS. Headquartered in South El Monte, CA, ESS Laboratories LLC (which we might call “ESS Reborn”) also owns the rights to the original slogan, “Sound As Clear As Light.” Unlike the speakers by ADAM Audio, GoldenEar, etc., these speakers look just like the original ones from ESS. President and CEO of ESS, Ricky “Rico” Caudillo, seen in the photo, told me that he wanted to stay with the original, highly-successful designs, but in recreating these designs managed to improve them in a number of ways, most notably in producing wider dispersion. A brief listen to the LD12 ($3295/pair), modeled on the original ESS Monitor, left me with a very positive impression.
