Audio Power Labs was a new name to me, and not without reason. The company was recently started up by a number of audio enthusiasts, including a number of ham radio operators and this was their first showing at a CES. The 833TNT monoblock amplifiers (price not set) use an interesting compliment of tubes, including two 833C tubes that are often used in small AM transmitters and a switching power supply.

Pass Labs showed off two nice beer fridges, er, amplifiers at this year’s CES. Lacking any model numbers or nomenclature, the top monoblock amp (the top two units) is a single-ended 200W amp ($45,000/pair) and the bottom monoblock is a single-ended 300W amp ($75,000/pair). Nelson Pass is shooting to use no feedback on these circuits and maintain the Super Symmetry design made popular in far less extreme applications. The new part for these amps is a brand new silicon-carbide FET. These FETs were initially designed for the military—way to turn swords into plow shares and space heaters, Nelson!—and Pass Labs intends on exploring their use in future products.

I met designer Hans-Ole Vitus in his room at the Venetian, where he was showing his new stereo amplifier, the Vitus SS 101 (pictured in the middle, $40,000). The SS101 puts out 50Wpc in class-A and 100Wpc in class-A/B. It also has a volume control, making it a single-source integrated amplifier that can be operated by remote control. The system really sounded great and Hans-Ole was a delightful chap.

“Biggest. Tube. Ever.” I said, in my best Comicbook Guy voice. The Kronzilla DX Mk.II ($32,000/pair) from KR audio of the Czech Republic uses two T1610 output tubes in parallel to achieve 100Wpc of triode power. The amp also uses zero negative feedback.

The Stello Ai500 integrated amplifier was shown in the April Music room. A 150Wpc integrated with a built-in high resolution DAC, the Ai500 sells for $3500 and ably drove power-hungry Magnepan speakers.

All of Bel Canto’s equipment was powered by their VBS-1 Virtual Battery Supply ($1495), which effectively takes their equipment off the electrical grid. The VBS technology was debuted at last year’s CES, but new this year are the VB-Ref power cables which connect the 12V output of the VBS-1 power supply to the component. Having tried these cables out in my own system at home during my audition of the Bel Canto DAC3.5 VBS, I can testify to their ability to bring out the best in this new Bel Canto gear.

I chilled with Lionel Goodfield of Simaudio in the Canadian manufacturer’s room around noon on Friday. We were both hitting our midday energy slump, so we sat on their comfy couch and chatted about two new products in Simaudio’s Evolution Series. The Moon 880M monoblock amplifiers ($38,000/pair) offer 800W into 8 ohms, 1600W into 4 ohms, and a staggering 2400W into 2 ohms. The amp utilizes bipolar output devices biased into class-A/B and uses zero global feedback. The amps sounded as relaxed as the Bob Marley tunes Lionel played near the end of our discussion. It was a great break from the CES frenzy.

Melody Valve HiFi of Australia was a new company to me. Pictured here is the Pure Black 101 Preamplifier ($4499) and PM815 monoblock power amplifiers ($7959/pair). The Pure Black 101 features an Alps remote attenuator, point-to-point wiring and Jensen copper foil paper in oil capacitors. The PM815 delivers 70W of pure class-A power using 845 output tubes.

Audio Research of Minnesota is located only a mile from my home, yet my visit to their room at this year’s CES was the first time I’d really met any of their staff. Getting pride-of-place in their CES system this year was the Reference Anniversary Preamplifier ($24,995), a two-chassis preamp celebrating the company’s 40th anniversary. According to the folks at Audio Research, this preamplifier has been a huge hit and has, to their own surprise, exceeded their sales expectations. Orders for the preamplifier will be taken through April 2011 and, unlike Brett Favre, will not come out of retirement.

“Go check out the Constellation Audio room,” said Jon Iverson. So I did. As I entered the room filled with unworldly looking gear I spied Michael Fremer, engrossed in one of his famous mix CDs, burned from his vast vinyl collection. Michael, ever the gentleman, relinquished the sweet spot to me and both of us took in some big, clean, transparent sound. Driving a pair of $150,000 Tidal speakers was Constellation’s Hercules amplifiers ($70,000 each), which are each able to put out a kilowatt of juice into 8 ohms and runs its first 250W in class-A.

The visual design of the amps is both striking and understated, clad in an all aluminum chassis. Each side of the amp has a diffuser grid which hides the amp’s heatsinks and allows for a chimney action to help cool the amplifier. All that aluminum also serves the purpose of mass-loading the amps to control vibration. Internally the amps mechanically float the sensitive signal carrying parts. That attention to vibration damping could be heard as stillness and ease, particularly when I played a high-resolution file of Robert Silverman playing the final fugue from Brahms’ Variations on a Theme by Handel. My time in the Constellation room was stellar.
