Yes, those are moving-coil woofers. From Martin-Logan, the electrostatic company. ML’s new Motion Series speaker, to be priced at around $3000/pair when it is available in the late summer, is a big brother to the Motion 40 tower. The speaker uses the largest yet Folded Motion XT tweeter to come from MartinLogan, marrying it to a 6.5" midrange unit and a pair of 8" woofers. and although the company is still based in Kansas, its speakers are now made in Canada. Though it was demmed with Peachtree amplification, the speaker suffered from the suboptimal room acoustics.

When WAVAC’s North American distributor, Covenant Audio Consulting, chose to stage the world debut of WAVAC’s eye-catching, directly heated single-ended triode HE-833v2 150W monoblock amplifiers ($79,900/presumably for the pair) with the massive SoundLab Majestic 845PX electrostatic loudspeakers ($35,000/pair), no one expected that high frequencies would project mostly from the top of the speaker, above the heads of seated listeners. Thus it was only when I stood that I was able to appreciate both the beautiful top and fine midrange transmitted by the HE-833v2s in conjunction with WAVAC’s PR-T1 transformer-coupled, three-chassis preamp ($30,900) and AC02 power conditioner ($22,900). Next time, I’ll bring my elevator shoes.

Krell used CES to launch no fewer than seven iBias high-efficiency class-A amplifiers. Called, by the company, "the most revolutionary design change in its 33-year history," the amps consume far less energy than traditional class-A amplifiers. iBias technology also reputedly eliminates crossover distortion, allowing low-level details, subtleties and spatiality to emerge without restricting dynamics. It does so by operating output transistors constantly at full power, so they never shut off, and adjusts power going to them according to demands.

Given that, for the first time since the dawn of the stereo era, cables were not part of my assignment, I never expected to find anything on my beat in the MIT room. But there, virtually dwarfed between MIT's top-of-the-line Oracle MA-X cabling and Magico Q3 loudspeakers, sang one of only two Spectral DMA-300 RS stereo amplifiers ($TBD) yet in existence. The sound through this stereo version of Spectral's monoblocks and Spectral's DMC-30 SS preamp and FDR-4000 CD player was spectacular.

"It's the best amp we've ever done," said an enthusiastic Kevin Deal about the PrimaLuna DiaLogue Premium HP integrated amplifier ($3999) and power amplifier ($3899). "The bass and control will work with ribbons and electrostats." Indeed, I found the sound really nice, with very natural timbres that rival or surpass those of the high-priced spread.

Qualia founder Masanori Fujii was born in France where his father was Japan's former ambassador to the country. Fujii still bridges both cultures by designing his products in Europe, but building them in Japan.

The Qualia DAC with USB is machined out of a single large block of aluminum and features 4 ESS Sabre 9012 DAC chips in a dual mono design. In addition to USB, inputs include AES/EBU, coaxial and optical. The DAC handles all PCM streams up to 24/192 and has both balanced and unbalanced outputs as well as headphone jack.

Available now for $39,000. Fujii adds that he is "not interested in any compromise in quality. The DAC has a very natural analog sound."

First seen last year at CES, the PureDAC has now been released and the company claims to have sold more than 1,000 units since August of 2013. Price is $1,690 and it handles up to 32/384 PCM, both DSD 64&128 and has a separate volume control for room and headphone listening. Designed in Germany, built in China.

Though I was in the Avatar room asking about new digital products, somehow this one was missed, so thanks to Jason Serinus for coming up with a photo for me. There was also a little confusion about the name of the product, but we're going with Scaena Mainframe for now.

The company info says that the new server plays all formats of audio and video and features an aluminum enclosure with liquid cooling, Xenon processor, "error correcting" RAM, and a custom 7" touch tablet to run everything. The Mainframe also runs off of a lithium battery power supply that can go for up to 12 hours on a charge.

No pricing or availability info yet.

Beijing's QAT Audio had their new fanless MS6i music server on display in the Venetian. NAS drives are supported via both WiFi and ethernet to supplement the user-replaceable 2.5 inch or SSD internal drives. Digital outputs include toslink, coax, BNC and AES/EBU and there are four USB ports.

All PCM formats up to 24/192 are supported and the company features a nice looking app for iOS and Android. Available mid-year for $2,990 in the US, currently available in China.

Soul Of the Music had their sMS-1000 media server on hand featuring the Vortexbox OS and the ability to handle PCM files up to 32/384 as well as DSD. The front panel has a slot for ripping both CDs or DVDs and pricing is dependent on type of output selected: $3,000 for both balanced and unbalanced analog outputs, $2,700 for coax, toslink, AES/EBU, and $2,500 for just USB 2.0
