Bel Canto's John Stronczer was excited. "The Powerstream amplifier's S/N ratio is 120dB measured at the speaker terminals!" I was impressed. This is equivalent to 20-bit digital audio, which means this digital-input monoblock, which costs $15,000 each, is one of the quietest amplifiers I have encountered. It offers 300W into 8 ohms, 1200W into 2 ohms. Audio data presented to the ST-optical inputs are reclocked and then converted to analog with a BurrBrown PCM1792. The analog signal is then fed to an output stage based on the well-regarded Hypex class-D modules, used in a proprietary low-gain…
John Siau of Benchmark (right) and Laurie Fincham of THX (left) gave a provocative presentation on the final morning of the show, entitled "Why Most 24-bit Audio Systems Still Deliver 16-bit Performance." The thesis was that even with D/A processors capable of operating with a dynamic range >20 bits, there is still the resolution bottleneck imposed by the amplifier. As I have pointed out in Stereophile's reviews, amplifiers with a sufficiently low noisefloor and a sufficiently large maximum voltage swing to equal hirez audio's dynamic range are a) rare and b) necessarily expensive.…
“It’s all on this USB stick,” declared digital genius and Wavelength mastermind Gordon Rankin, as he pressed lots of data into my hand. Once accessed, I learned that I had enjoyed a MacBook Pro Retina 15 16G-RAM/480G-SSD connected via Thunderbolt to a 4T library; Wavelength’s battery-powered Crimson + Denominator DAC ($9000) connected to the computer via an AudioQuest Diamond USB; Wavelength’s new Europa analog/digital preamplifier ($7500) with ESS ES9018 DAC chip, network support, three analog inputs, and either Ethernet or WiFi remote; Wavelength’s new all-silver Napoleon 300B amplifiers;…
Resonessence—what a great name for the equipment that closed out my three days of blogging RMAF 2013. Happily it sounded really good as well, especially when JA pointed out that the reason this simple system’s top at first seemed rolled off was because the only way to align our ears with the tweeters of the 20-year old, unusually short B&W mini-towers was to either crouch way over or kneel on the floor.
Thus did Resonessence Labs of Kelowna, BC Canada bring me to my knees. But why, pray tell, did the company pair its Invicta Mirus ($4995), their top-of-the-line, all-in-one music…
Ray Kimber always gets great sound at shows, but this year, although he was still using four Sony SS-AR1 loudspeakers hooked up with Kimber Select cables and an EMM DAC to play his four-channel IsoMike DSD master files, there was something extra-magical happening in the room. Both pianist Fan-Ya Lin's album Emerging and the Romantic Album from violin and piano ensemble the Formosan Duo, sounded tangibly real. The key, it turned out were the gigantic, 300lb MTRX class-A/B monoblocks from EMM Labs, can be seen in my photo. This brute will output 1500W into 4 ohms and, in Ray Kimber's words,…
Wired with Transparent cables, the extreme audio system in the large room at the Denver Tech Center Hyatt—dCS Vivaldi digital source, VTL TL7.5 III preamp, VTL Siegfried power amps, Wilson Alexandria XLF speakers driven full-range and twin Thor's Hammer subwoofers driven by 250Wpc Parasound Halo A 21 amplifiers below 38Hz—worked its magic both on the disco-meets-EDM of Daft Punk's "Lose Yourself to Dance" and the delicate harmonic traceries of Dave Wilson's Debussy violin sonata recording transferred to DSD by Puget Sound's Bruce Brown. In both cases, there was a sense of loss when the music…
We end this show report as we started, with a photograph (this time by John Atkinson) of singer Lillian Boutté, who both opened and closed the RMAF with her band Eric Gunnison on piano, Mike Marlier on drums, and Mark Simon on bass, in the Denver Tech Center Marriott’s Atrium.
I’ve seen no official statistics, but my strong feeling is that the Rocky Mountain Audio Fest, perhaps for the first time in its 10-year run, saw decreases in attendance, energy, and overall excitement. Opening day was quieter than in the past; on floors 4 and 5 of the Marriott Atrium, exhibitor rooms were often…
It ranks among the most astounding turnarounds in American music. John Zorn—erstwhile bad-boy impresario of the downtown New York jazz scene—spent last month touted as a modern master, and Manhattan's pride, by the city's most venerable institutions of high culture: the Metropolitan Museum, the Guggenheim, Lincoln Center, Columbia University, and NYU.
The occasion was Zorn's 60th birthday (which fell on Sept. 2), and these vaunted halls and galleries hosted concerts of Zorn playing, or fronting ensembles of favored collaborators playing, his compositions almost every night all month long…
Friday, October 25, 6–9pm: Whetstone Audio (2401 East 6th St. #1001, Austin, TX) will host its next "Hi-Fi Hootenanny." Rega's Paul Darwin will introduce the company's new Elicit-R integrated amplifier and Saturn-R CD player/DAC, which made their official debuts at last week's Rocky Mountain Audio Fest. For more info, visit WhetstoneAudio.com.

Reference Recordings LP RR-2 and CD RR-22CD. Tam Henderson, prod.; Keith Johnson, eng.
This is unquestionably one of the best recordings Reference Recordings has done. The sound of the LP is up-front and quite bright, giving the orchestra that peculiarly nasal quality I usually associate with small French orchestras. There is truly remarkable detail and naturalness here; I was about to write that the recording makes the…
