"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...

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, $750), and Tranquility Bases. (In the photo, Ted is pointing to the HFT affixed to the front of the radio.)

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.

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).

I did not see the same kind of impressive attendance I've become used to seeing on RMAF's opening day&#151lines stretching through the lobby, out the doors, and around the parking lot&#151but, at just past 12pm this afternoon, there was nevertheless a fine crowd of anxious hi-fi enthusiasts gathered round the registration tables.

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.

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, and a singer whose name was not listed in the program.

The 2013 Burning Amp, the DIYAudio forum's "annual experiment in temporary community dedicated to radical self-expression and self-reliance," got off to a slow start. Although a semi-hidden posting about the one-day, all-volunteer event, held in six rooms at San Francisco's Fort Mason Center on Sunday, October 6, appeared months ago, the email blast to the Burning Amp mailing list only went out late on October 3. As a result, attendance was light, making it much easier to listen to music in the extremely live, audio unfriendly rooms.

Central to every Burning Amp is Nelson Pass (above), whose boundless generosity and support to DIYers worldwide has made him a father figure of sorts.
