LATEST ADDITIONS

The large, superb-sounding system in the High Fidelity Services room left me deeply impressed. The system was headlined by the debut of the Verity Audio Monsalvat speaker system with its included Pro-6 six-channel crossover ($675,000 total) and three of Verity Audio's Monsalvat Amp-60 stereo amps ($58,000/each). Together with a TW-Acustic Raven phono preamplifier ($18,000), TW-Acustic Raven Black Knight turntable ($42,000) with debut Raven 12 and 10.5 tonearms ($11,500 total) and debut Ortofon MC Century cartridge ($12,000), Melco N1ZH MK1 music server ($4995), debut Signal Projects cables, Vibex power distribution, debut CAD GC-1 ground control unit, debut Symposium Pro amp stand, Vibex isolation feet, and SRA rack, the system cost a mere $1,115,405. Note that it was not the only system at RMAF in this price range.

On the eve of the 15th annual Rocky Mountain Audio Fest, being held this weekend in the newly remodeled but acoustically challenged Denver Marriott Tech Center, show organizer Marjorie Baumert revealed the show's future venue: beginning in 2019, RMAF will relocate to its new home in the brand new Gaylord Rockies Resort & Convention Center, just five miles from Denver International Airport. Baumert made the announcement alongside Gaylord Rockies' Director of Sales, Jeff Lindeblad (on the right in the photo above), and used the occasion to reveal that show dates for next year will move up a month, to the first weekend in September.

The most notable aspect of Benchmark Media Systems' DAC3 HGC ($2195), which I favorably reviewed in the November 2017 Stereophile (footnote 1), is its low noise floor. John Atkinson's measurements corroborated Benchmark's claim that the DAC3 is capable of "at least" 21-bit performance. While significantly less than the theoretical potential of a 24-bit data format, 21 bits is still the state of the art, and corresponds to a dynamic range—the ratio of the highest achievable digital-domain volume to the DAC's internal noise—of 128dB. That's well above the dynamic range that most power amplifiers can achieve. A good-measuring high-end solid-state amplifier is likely to have a dynamic range—the highest attainable ratio of signal to noise—of about 100dB ref. its maximum power.
