Thiel’s long-awaited trickle-down speaker from 2008’s ground-breaking CS3.7, the CS2.7 ($9900/pair), made its North American debut in one of the Denver Audio Designs rooms. It combines the coaxial HF/MF unit that the late Jim Thiel developed for the ‘3.7 with a proprietary 8” woofer, reinforced with a passive radiator to give claimed bass extension to below 35Hz. Frequency response is specified as 35Hz–20kHz ±2.5dB, and crossover filters, of course, are all first-order. (No impedance spec was given; Thiel speakers have always been current-hungry.) The CS2.7s were demmed with Aragon Iridium 400W monoblocks ($7998/pair), an Aragon Sound Stage digital preamp ($4499), an Arcam CD37 SACD/CD player ($2299), an Arcam FMJ D33 D/A processor, and Straight Wire Expressivo interconnects and speaker cables, and Straight Wire Blue Thunder AC cords. The sound of Ryan Adams’ “Dirty Rain” had extended lows, grain-free highs, and superbly stable, well-defined stereo imaging.

Blues singer Jimmie Lee Robinson was singing when I entered the Aaudio Imports room, his jingling spurs sounding preternaturally real on the 6’-tall Lansche Audio 7 speakers ($108,000/pair). Like the Lansche 5.1 that I reviewed in July, the 7 uses an RF-energized corona tweeter to produce clean, transparent-sounding highs. Amplification was the new Ypsilon SET100 monoblocks ($125,000/pair) with a tubed Ypsilon PST-100 Mk.II preamp and tubed VPS-100 phono preamp, these two both favorites of Mr. AnalogPlanet, Michael Fremer.

Listening to HDTracks’ 24/192 download of the Jimmy Cobb Quartet’s Jazz in the Key of Blue, I finally heard what a well-tuned MSB system can do. “So musical!” I wrote in my notes. Instrumental timbres were excellent, with the warmth and fullness of Roy Hargrove’s trumpet portrayed with near tube-like roundness and warmth. Combined with the air and depth conveyed by the high-res recording, and the sheer presence of the drums, the experience opened a portal to audio nirvana. I could have spent hours exploring music in multiple formats on this system, and still have wanted more. It killed me to have to leave the room so soon. Only the reality of many more rooms to cover before show’s end kept me from staying longer.

With a fanfare at 4pm, Sunday October 14, in the Denver Tech Center Marriott's Atrium, the Denver Broncos Half-Time Band, courtesy of Kimber Kable's Ray Kimber, brought the Show to a close. According to Show organizer Marjorie Baumert, "We had about 150 more exhibitors (according to the badges), about 3600 attendee days (approximately 100 more than last year). We had 1295 attendees pre-register and that was an all-time record (last year was 1100). . .

The next-to-the-last demonstration I heard at RMAF 2012 was among the two or three most impressive. Doing business as Volti (it means to move forward) Audio, Maine resident Greg Roberts builds horn loudspeakers that seem to embody both the superb craftsmanship and musical impact of America's finest vintage-audio products. His newest, the Vittora ($15,000/pair), is a three-way loudspeaker with a horn-loaded 15" bass driver, horn-loaded 2" compression driver for the midrange, and horn-loaded 1" compression driver for the treble, with passive crossover networks, stepped attenuators for the mids and trebles, and an all-plywood cabinet in a choice of veneers. Based on a brief audition with EMM Labs digital source components and a BorderPatrol S20 single-ended 300B amp ($13,750), I can only say that the Vittora is, if anything, underpriced. My first question to Mr. Roberts was, "Who do I have to kill to borrow a review pair?"; we're still working out the details. . .

As someone who fell in love with the sound of Apogee full-range ribbon speakers in the early 1980s, I made a point of visiting the room featuring Analysis Audio planar ribbon speakers. Driven by Arion HS-500 amplifiers ($5995/pair), which combine a class-D output stage with a tube input and driver stage, via JPS cables, a track from Patricia Barber’ Companion album sounded sweet and rich on the Omega ribbons ($24,200/pair with external crossovers), but with a touch of color in the mind-bass that was audible on kick drum.

A reader complained recently that exhibitors at audio Shows tend to demonstrate cost-no-object systems. He was right—they do. As Stephen Mejias has explained, exhibiting at a show is an expensive proposition and most companies go for broke with the systems they show, wanting to get the maximum “Wow factor,” hence return, on that investment.

Colorado retailer Audio Limits was no exception, its large room off the Marriott’s atrium featuring Venture Ultimate Reference loudspeakers ($135,000/pair) driven by FM Acoustics 115 monoblocks ($108,200/pair), an FM Acoustics 245 preamp ($25,800), with the source either a PC laptop running XX High End software, a Weiss Jason transport ($22,7070), or a Weiss Man301 network player ($9083 without DAC), Weiss Medea+ FireWire D/A converter ($21,799) . . .

Styled to resemble Sonus Faber’s cost-no-object “The Sonus Faber” flagship design, the new Sonus Faber Venere range of speakers made its debut at RMAF. Costing $2498/pair, ie, around less than 2% of the big speaker’s price, the Venere 2.5 was demmed with an Audio Research DSI200 class-D integrated amplifier ($5995), a Wadia Model 121 decoding computer ($1299), a Pro Ject Xtension turntable with Sumiko Blackbird cartridge ($3699) a Pro Ject Phono Box ($999), and Pro Ject’s new Stream Box ($1999). The LP of Jeff Buckley’s classic album Grace was reproduced with appropriate impact and a color-free tonal balance. Even considering the relatively affordable price of the system, this was still one of the better-sounding rooms I heard at RMAF.

In the other Hear No Evil room, Kevin Deal introduced PrimaLuna's new DiaLogue Premium Integrated amplifier ($3299). This amp can be fitted with KT66/6L6GC, KT77/EL34, or 6550/KT88 tubes and, driving a pair of KEF R900 speakers ($5000/pair) did sonic justice to Nils Lofgren’s homage to Keith Richards, “Keith Don’t Go.” Source was PrimaLuna’s ProLogue Premium CD player ($3299), which now has a 24/192k-capable USB input based on an M2Tech module as well as the tubed clock circuit used in the earlier Prologue Eight player.

No, I’m not talking about one of the young women who always seem to drive Stephen Mejias to distraction at shows. Rather, I’m speaking of Estelon’s Model XB loudspeakers ($32,900/pair). Designed for more modestly sized rooms, this Estonian speaker was producing realistic, full-range sound courtesy of Vitus Audio’s SM 010 monoblock amplifiers, SL 102 preamplifier, and SCD010 CD player. Power Conditioner was Silver Circle Audio’s Tchaik 6, cabling Kubala-Sosna’s Elation, and rack and feet from Stillpoints.

It was a pleasure to make the acquaintance of Bob Neill, a fellow graduate of Amherst College and proprietor of Amherst Audio in Amherst, MA. In a system headlined by JM Reynaud Abscissa loudspeakers ($5500/pair) bi-amped with Crimson 640E monoblock amplifiers ($6000/pair), and completed by the Crimson 710 solid-state preamplifier ($7000), Resolution Audio Cantata ($6500), and Crimson interconnects ($360/1m pair) and bi-wired speaker cable ($1070/8' pair), I enjoyed the kind of cultivated sound that discriminating listeners crave. True, there was some extra resonance in the treble that made piano sound a mite metallic, but the midrange beauty of Antonio Lysy’s cello on Yarlung Records’ recording, Antonio Lysy at the Broad, was very special.

Audio Note now handles its US sales directly from the UK. The sound in their room may have been warmer than neutral, but it had an immediacy that I enjoy. Here, the vividness of a classic recording of music from Glinka’s Ruslan and Ludmila struggled to triumph over the bass commentary from the adjacent room’s Göbell behemoth. When the booming subsided, Jennifer Warnes emerged triumphant.

People sat up and took notice when Sanders Sound Systems released their Model 10 full-size electrostatic loudspeakers with analog electronic crossover amplifiers a few years back. The latest version, Model 10c ($13,000/pair) was delivering solid, full-range sound from a system that also includes Sanders Magtech Stereo amplifier ($5000), new preamplifier that combines both line and phono stages ($4000), and their own interconnects and speaker cables.

It was great to again encounter Silverline’s flagship Grand Bolero loudspeaker ($35,000/pair), displayed by Scot Markwell of Southern California’s Audio Summa. Together with Kuzma’s Stagi S NSE 12" w/TVA tower and Crystal Cable Silver ($2950) and Stabi SD in brass w/external power supply ($3700); BEL’s 1001 Mk.IV amplifier (NFS); and Furutech’s Lineflux RCA interconnects ($2704/1.2m pair), Speakerflux speaker cables ($3645/2m pair), and Powerflux power cords ($3007/1.8m each), the system produced admirable full-range sound.
