RMAF 2011

Colorado Springs retailer Audio Limits was filling one of the very large ground-floor rooms at RMAF with sound, courtesy of the massive Venture Grand Ultimate loudspeakers ($90,000/pair) driven by the new AMP M1 solid-state monoblock amplifiers from BMC ($7790 each, $15,580 pair). Source was the BMC BDCD1 belt-drive CD transport ($5990), the BMC DAC1 Pre (HR) D/A converter/preamplifier ($6290), with Silversmith The Silver interconnects and speaker cables, Stage III power cables, and Weizhi PRS-6 power distributor.

I listened to a track I haven't heard in years in this room, Michel Jonasz's "Les temps passeé," from the CD La fabuleuse histoire de mister swing (1987), and was blown away by the enormous sound, the huge dome of ambience that was defined between and behind the speakers, and the sheer effortlessness with which the music was presented.

In the room presented by Audio Physic, Acoustic Signature, and Trigon, music was sweet and nuanced, played at low volumes, but nevertheless involving and deeply enjoyable. I admired the subtlety of touch, richness of texture, and ease of flow. We listened to a few minutes of One Foot in the Gutter, a live, 1960s recording by the Dave Bailey Sextet, and I swear I could hear the joy and humor in the band’s playing.

In my opinion, one of the coolest-looking systems of the show was pieced together by New York City’s Audioarts: Rethm Maarga loudspeakers ($8750/pair), Fi amplification, and a Lector CDP-6 CD player. The sound was just as good as the appearance: immediate and realistic, with a rich, detailed midrange.

Audioarts also presented a system comprising BMC amplification (supported by a SolidSteel stand) and Zellaton loudspeakers ($24,950/pair). Every Zellaton driver is completely handmade and takes up to three weeks to produce. The speaker cabinet uses a semi-open construction meant to minimize cabinet resonances.

Audioengine’s new A5+ ($399/pair in gloss black and white; add $70/pair for bamboo) adds a remote control, RCA and mini-jack inputs, a rear-panel USB charge port, rear-panel heatsink, upgraded speaker binding posts, and a variable preamp audio output. In addition, the A5’s large circular ports have been replaced by narrow slotted ports, said to provide a smoother, cleaner low end. (Who doesn't want that?)

Avatar Acoustics’ Darren Censullo always puts together an impressive system. Every aspect seems carefully considered, made to complement the whole.

It looks like the best-selling QB-9 USB DAC until you notice the level meters and the level control next to the display. This is Ayre's new QA-9 A/D converter, aimed at audiophiles who want to rip their LPs with the highest possible quality. The analog input is balanced and there are both USB and AES/EBU digital outputs. The ADC chip is fed by an input stage featuring Ayre's zero-feedback, discrete circuitry and it will output 24-bit LPCM at up to a 192kHz sample rate. However, there's no reason why it couldn't also output DSD data. The QA-9 will be in production in the first quarter of 2012 and while price is not yet decided, it will be somewhere between the QB-9's price and $5000, I was told.
