Each Xs channel has two chassis, one for the power supply and the other for signal amplification. The amplifier acts as a voltage source, and is rated at 300W into 8 ohms, 600W into 4 ohms, and 1200W into 2 ohms. It is biased to ensure make certain that the amplifier remains in class-A mode into all loads. Each channel has 122 output devices with a total rating of 10kW, and the extensive heatsinking allows the Xs 300 to deliver 2kW into a load "all day long." Though the Xs 300 stack was a silent exhibit, the company was using the more modest $65,000/pair Xs 150s to drive the Pass Lab RM2 loudspeakers, which showed a wide dynamic range and outstanding detailing.
Danish manufacturer Raidho demonstrated its $30,000/pair, 88 lb, X3 loudspeakers at CES. The remarkable slim towers have four dedicated 4" ceramic midbass drivers and one 8" side-mounted woofer, in addition to a magnetic-planar tweeter that is crossed over at 3kHz.
Ron Sutherland of Sutherland Engineering taught me all I need to know about Nixie tubes at CES. Used as the main visual display device used in his Reference N-1 preamplifier and in his Destination Line-Stage preamplifier's control unit shown in the photo, the Nixie tube was invented in 1955 as the first electronic display tool for reading out the numbers 09. The Nixie's designers fashioned a wire mesh into 9 layers, each layer in the shape of a number, resulting in a tidy small stack. This tiny wire stack was inserted into a small glass envelope, filled with neon gas, and then sealed. When any of the separate metal layers was charged with 175 volts, the neon gas around the wire ionized, and lit up. When plugged into a circuit board, the tube would read out the numbers, with each number appearing at a different depth. Paul was fascinated with the retro look of this type of readout, so he has installed it in his $15,000, three-chassis Destination line stage, and into his new $10,000 reference N-1 preamplifier.
I heard very detailed and rich sound in the exhibit run by Lamm Industries and by Verity Audio. The system setup included $95,995 Verity Audio Lohengrin II speakers, $37,190/pair Lamm ML2.2 single-ended, dual-chassis 18W amplifiers, a $28,000 Kronos turnable with a $5,200 Phantom II XL12 tonearm, $5500 Dynavector X1Vs cartridge, and $97,000 worth of Kubala-Sosna interconnects, speaker cables and power cords. Julien Pelchat, the Vice-President of Verity Audio, walked me through the design of the Lohengrin II speakers.
T+A's lively and energetic Jochen Fabricius was eager to fill me in on the new, 3-way, 183 lb, $55,000/pair T+A CWT 1000-8 SE floorstander. This speaker uses a 25" by 2" electrostatic line tweeter that covers the frequency range from 2kHz to 40kHz.
Abbey Masciarotte, Tannoy's representative at CES 2015, showed me the company's floorstanding Canterbury loudspeaker. The Canterbury has a striking retro look and uses a dual-concentric 15" drive unit that mounts a high-frequency compression driver inside the throat of a 15" woofer.
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.
Several seconds after I began listening to it, I knew that Theta Digital's Prometheus monoblock amplifier ($12,000/pair) was different from other amplifiers. The violins and brass were more dynamic, and had more pace. The orchestra sounded more three-dimensional, depicted in relief by a degree of hall ambience I hadn't heard when I played the same recording through my reference solid-state stereo amplifier, a Mark Levinson No.334.
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).
Thiel's press conference at the Sands Convention Center on Day One of the 2008 CES opened with a detailed critique of the complexities and challenge of installing a home theater system. Ekin Binal, Vice President, Product Development, of BICOM, an IT company partnering with THIEL to address these issues, spoke in detail about the complex, labor intensive, time-intensive, cost-intensive installation of multiple speakers and channels. Furthermore, updating such a home theater system is never simple nor convenient, nor is moving a system from an old house to a new house either simple or inexpensive. Because installation is custom work, there is no universal package a single manufacturer can create that can fit most domestic locations.
