Sidebar 3: Measurements
I used DRA Labs' MLSSA system and a calibrated DPA 4006 microphone to measure the Wharfedale Diamond 10.7's frequency response in the farfield, and an Earthworks QTC-40 for the nearfield responses. My estimate of the Wharfedale's voltage sensitivity was a fairly high 89.7dB(B)/2.83V/m, which is within experimental error of the specified 90dB. The Diamond 10.7's electrical impedance and phase angle are shown in fig.1. The phase angle is high only when the impedance magnitude is also high, ameliorating its negative effect. While the magnitude reaches a minimum value…
For its 10th anniversary, the Rocky Mountain Audio Fest has lined up some stellar entertainment. With more than a little help from Kimber Kable, Nordost Corporation and Reference Recordings, Marjorie Baumert began the celebration with a pre-show performance by vocalist Lillian Boutté. The only musician since Louis Armstrong to be decorated Ambassador of Music by the city of New Orleans, Boutté brought her 30 years of experience with jazz, gospel, and R&B to the first of three performances at the show. Backing her up were Eric Gunnison on piano, Mike Marlier on drums, Mark Simon on bass,…
Every year, the Rocky Mountain Audio Fest, which starts today in the Denver Tech Center Marriott, kicks off with a pre-show gathering for exhibitors and press in the hotel’s Atrium. With each attendee handed two coupons for free drinks, it’s a great way to come down after an intense day of travel and room set-up. Show organizer Marjorie Baumert, shown with Ric Mancuso of Reference Recordings, was having an especially jolly time celebrating the show’s 10th Anniversary.
I did not see the same kind of impressive attendance I've become used to seeing on RMAF's opening day—lines stretching through the lobby, out the doors, and around the parking lot—but, at just past 12pm this afternoon, there was nevertheless a fine crowd of anxious hi-fi enthusiasts gathered round the registration tables.
Earlier this year, I reviewed PSB's Alpha PS1 powered desktop loudspeakers. Pleased by their small size, great looks, and clean sound, I purchased the review samples. Now, PSB offers the matching SubSeries 100 subwoofer ($249).
With an attractive high-gloss black finish and measuring just 6 3/8" wide by 6 3/8" high by 7 7/8" deep, the SubSeries 100 should easily fit on or around most desktops. The sealed box design uses a 50W class D amplifier and a 5 1/4" drive-unit, computer optimized to maximize bass extension while minimizing distortion, explained Paul Barton. Volume, crossover, and…
I've been kicking myself for not making it out to Brooklyn to hear YG Acoustics' flagship Sonja 1.3 loudspeakers while they were in John Atkinson's system, so I was especially pleased to see and hear the smaller Sonja 1.2s ($72,000/pair), driven by four compact Mola-Mola Kaluga monoblocks ($15,000/pair) and Mola-Mola's similarly cute Makua preamp ($10,000). (Like the Sonja 1.3, the 1.2 comprises the 1.1 tweeter/midrange module and interlocking bass module, but lacks the 1.3's second bass module.) Music was sourced from a laptop through Luxman's DA-06 DAC ($4990) and everything was tied…
With up to 75 rooms to cover on multiple floors of the Marriott’s tower, I decided to check out Synergistic Research’s much-heralded new products before the show officially began. Inventor Ted Denney decided to dem his new babies, not with the expected megabuck system, but rather with a Bose radio. Positioned atop one of his Tranquility Bases, used as shelves on a Solid Tech rack, the radio played a vocal track by Anne Vada and Aki Fukakura as Denney demonstrated the cumulative effects of his tiny aluminum passive HFTs (High Frequency Transducers, $299/5 pack), active FEQ (Frequency Equalizer…
"What is this music?" asked Jason Serinus (above).
We were sitting in the VTL room, where a pair of Wilson Alexia speakers ($48,500/pair) were being driven by VTL's S-400 stereo amplifier ($33,500), TL-7.5 Series III preamp ($20,000), and TP-6.5 phono preamplifier ($10,500 with transformer).
"It's 'Lose Yourself to Dance,' my favorite track from Daft Punk's Random Access Memories LP," I whispered, played on a Spiral Groove SG1.1 turntable and Centroid arm ($31,000) fitted with Lyra's new Etna MC cartridge ($6995). The rest of the system included dCS's Paganini 4-box SACD player,…
