According to T+A (Theory plus Application) ElektroAkustik's Lothar Wiemann, the manufacturer is one of Germany's largest electronics companies. (It is distributed in the US and Canada by Dynaudio North America.) This company makes the 1000 W M10 monoblock hybrid amplifiers ($33,0000/pair), where the output stage uses tubes to handle the voltage and transistors handle the current.

Simaudio Moon's Lionel Goodfield, Vice President of Marketing, spent a relaxed half hour discussing amplifiers, cars, and various other topics of mutual interest. Along the way, he introduced the Moon Evolution 860A dual-mono amplifier ($14,000), shown sitting by itself in front of the other Simaudio products. The amplifier delivers 200Wpc into 8 ohms, 400Wpc into 4 ohms, 800Wpc into 2 ohms, the power doubling "all the way down to 1 ohm." It features special output devices made by Motorola for Simaudio. The sound from the Dynaudio C1 Signatures was clear, fast, smooth, and open.

Perfect8 Techologies' exhibit suite at the Venetian proved to be one of the most crowded I entered. Perfect's CEO, Jonas Rantila, was introducing his new floorstanding speaker, the Point Mark II Evolution ($115,000/pair). This three-way, speaker features an Air-Motion Transformer tweeter and two midrange drivers mounted on a glass baffle (there's no enclosure for the tweeter or midrange drivers), sitting on a single glass-enclosure housing a pair of 10" subwoofers powered by a 400W, DSP-controlled amplifier hidden within the enclosure. Power for the midrange and tweeter was supplied by a 165 lb, 500Wpc, solid-state Bridge Audio Laboratory (BAlabo) BP-1 Mk.II stereo power amplifier ($88,500). The BP-1's importer, Fred Nadel, told me that the amplifier's output stage runs in class-A for the first 40 watts.

Theta Digital, the pioneer of digital separates, announces the mighty Prometheus monoblocks ($12,000/pair). Heard in pre-production mode, with bass so strong and tight that it sent me into the hallway to discuss the product, the 200Wpc into 8 ohms monoblock is due out "within 90 days" (to quote a mantra oft-repeated at CES 2013).

I stumbled into the Naim Audio Exhibit and was faced with a wall of amplifiers and electronics. Chris Koster, of the Sound Organisation, Naim's US importer, guided me through the Naim amplification that was being used to drive the tri-amplified loudspeakers in the room. Starting from the left, the rack held three NAP-500 solid state amplifiers ($28,000 each).Sitting just above the three amplifier chassis at the extreme left was a Naim Snaxxo 362 ($3500) active crossover; its Naim Supercap power supply, sitting at the top of the center column, powered the Snaxxo. Each of the amplifier's individual NAP-500 PS power supplies occupied the three lower shelves at the center of the rack. The two top center shelves held the power supplies for the NAC552 preamplifier ($28,000) and the NDS Media Streamer ($11,000), whose control chassis could be found at the extreme right of the rack.

I ran into Dan D'Agostino, in the hallway of the Venetian. He was hurrying off to a meeting, but had a moment to mention that his amplifiers were being used in live exhibits in several rooms, including YG and Light Harmonic DaVinci, among others. I asked if there was anything new at the show, and he smiled and mentioned the new Momentum preamplifier. I found the D'Agostino room and his partner Petra, showed me the preamplifier, which was on passive display.

English manufacturer Chord Electronics is known for its sophisticated CD players, which use sophisticated DACs. Indeed there was a huge picture denoting Chord's latest-generation DAC, the QBD 76, at the center of the back wall. As my beat was amplifiers, Chord's designer, John Franks (pictured above), spent the next 30 minutes walking me through the design of Chord's latest amplifier, the SPM 1200 Mk.II ($14,000), a solid-state, 350Wpc stereo mode. The amplifier sits at the bottom of the short stack of audio equipment John is leaning on. He explained that the amplifier has a high-frequency, 2kW, switch-mode power supply, and uses an output stage based on dual-die, lateral-structure MOSFETs with a soft turn/on-turn/off characteristic. This allowed John to use a sliding class-AB design.

When I visited Nagra's exhibit at the Venetian, Jean Paschal Panchard, Nagra's representative, was out for a meeting. I asked his colleague, Jorgen Olofsson of Marten loudspeakers (the $77,000/pair Marten Coltrane Tenors were being driven by Nagra electronics), what was the "newest" Nagra product being shown. He mentioned Nagra's new Melody high-end solid-state preamplifier. Like the all-tube Jazz preamplifier, the Melody features the traditional Nagra look with the modulometer on the front face to indicate output signal level. The Melody weighs 7 lbs, and has a rated bandwidth of 10Hz–50kHz, +0/–1dB. Like the Jazz, all five RCA inputs and the two switchable outputs (one RCA and one XLR) are all on the back panel. It can accept an external power supply, such as the Nagra ACPS II or the new multiple power supply name the Nagra MPS. The Melody’s suggested retail price in the USA will be $7500 and the optional phono stage will cost $1500.

Cary Audio demonstrated its CAD-211 ($20,000/pair) 150W tube amplifiers, two-chassis piece SLP-05 tube preamplifier ($8500), and CD-303T SACD player ($6500), with Tannoy's flagship floorstander, the Kingdom Royal ($55,000/pair). All cabling was by WyWires. The Tannoy is a four-way speaker design, with a 15" woofer handling music below 150Hz, the midrange handling up to 700Hz, the tweeter up to 17kHz, and the super-tweeter up to 65kHz. The Kingdom Royal is very sensitive at 94dB/W/m —the resulting sonics were clear, delicate, and musically involving. And as John Atkinson said when he listened to this system, “there’s no substitute for horsepower.”

Pass Laboratories, who introduced the Xs line of flagship 150W and 300W amplifiers at last year's CES, brought out a new preamplifier, the Pass Labs Xs preamplifier (price to be determined). It features a single control chassis that carries the line level audio signal and an external power supply. The Xs preamplifier was used to drive a pair of Pass Labs Xs300 ($85,000/pair) power amps connected to a pair of Sony SS-ARI ($27,000/pair) loudspeakers. The Pass Lab team obliged me by playing a fresh vinyl pressing from Japan of the Proprius Cantate Domino recording. The dynamic range and control of the pipe organ pedal notes was remarkable, making the Pass Labs one of the best-sounding setups I heard at the show the first day.
