RMAF 2019

Do VAC tube components possess chameleon-like powers? That's the question I've begun to ask: Each time I encounter their components in different settings, I hear radically different sound. Here, from a system including Nola's towering new Concert Grand Reference Gold 2 loudspeakers ($250,000/pair), an Audio Research REF CD8 CD player, Nordost Odin 2 cabling, and VAC's Statement 450S IQ amplifier ($63,000), Master line stage ($28,000), and VAC DAC MK II ($12,000), the sound was midrange preponderant—not at all what I expected to hear from either VAC electronics or a 275lb open-baffle line-source array design with a claimed frequency range of 18Hz–100kHz, 91dB sensitivity, and 8 ohm impedance. I think the room was simply too shallow in depth, with seats too close, for these speakers to strut their stuff.

For a room too small for Tekton's massive, multi-driver Moab loudspeakers ($4500/pair), Parasound and Tekton were getting surprisingly good sound. The small system lineup was headed by the new Parasound Classic 200 Integrated ($1195), which includes an all-analog signal path, analog bass management with high and low pass outputs, a DAC whose circuitry is, in the company's words, "pulled directly out of the award-wining Halo P-5," and far more goodies than you might expect at this price point.

In the Gaylord Hotel’s North Tower, where room after room, regardless of its size or layout, seemed conducive to good sound, Raidho Acoustics was making a major impression with the world premiere Raidho TD2.2 2.5-way loudspeakers ($46,000/pair in black).

After talking with a number of exhibitors and attendees, I’d have to call the Rocky Mountain Audio Fest’s daring move to a new and very different venue—a controversial if also inevitable move—a success. Everyone I spoke to was happy with attendance, and the sound in the hotel rooms was generally excellent.

The Hellena MK II uses a 604-8E alnico coaxial driver, made by Great Plains Audio, that owes its design to the original Altec 604-E. Its woofer, Great Plains Audio’s handmade Model 515-C low-frequency loudspeaker, incorporates a massive alnico V magnetic assembly. There's also an alnico horn supertweeter.

Ray Kimber of Kimber Kable was in “You gotta” mode. After he told me that WBT, the 34-year-old German company that supplies connectors and cable terminations to hundreds of manufacturers worldwide, had a new, environmentally friendly facing process that made for better sound, I arranged to meet with WBT founder and CEO Wolfgang Thoerner on Sunday morning to discuss their new "WBT-PlasmaProtect" PVD (Physical Vapor Deposition) plasma process.
