LATEST ADDITIONS

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.

When I walked into the Boulder room, I actually started to giggle. I was told Boulder was showing off some large new amps, but I was not ready for what I saw. Sitting atop plinths of solid granite were the new 3050 monoblock amplifiers. Unlike most monoblocks, the left and right amps, seen here with Boulder's genial Rich Maez, are designed as mirror images of one another for greater visual appeal. These class-A amps put out 1500W into 8 ohms, use 120 output devices, require a dedicated 240AV AC outlet, and weigh 400 lbs each. Oh yes, they cost $180,000/pair. They will begin shipping soon and I am told that orders are already in for these beasts.

Ayre showed off their new VX-R stereo amplifier, a stereo version of their lauded MX-R monoblocks. Rated at 200Wpc into 8 ohms the VX-R is priced at $14,950. The amp is a zero-feedback design, featuring fully balanced discrete circuitry. As usual from Ayre, the chassis is beautifully made of milled aluminum. The sound of the VX-R, driving the TAD Compact Reference monitors was wonderful.

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.

At last year’s CES, many of my favorite rooms featured Sweden’s Marten speakers. The same held true this year. I expected good things when I stopped by Marten’s own room at the Venetian. Not only where they showing off the new version of their Coltrane 2 speaker ($95,000/pair) but also their first amplifier design, the M Amp ($45,000/pair). These monoblock amps have scary low distortion—0.05% at 400W into 8 ohms and use a class-D stage that switches at 600kHz. The amp can output 550Wpc into 8 ohms, 1000Wpc into 4 ohms, and 1700Wpc into 2 ohms.

The folks in the Marten room seemed in dire need of some good music when I came in, having suffered through too much audiophile approved crap during the show. I handed them a CD of the XX, a band I love, and we all bobbed our heads to this sparse but funky Pop. I find this album doesn’t work at all if a system cannot get the interplay between the bass guitar and kick drum right. The Marten system did this very well, sounding rich and articulate. The M Amps never let on that they were class-D amps, sounding more like super powerful tubes or a richly voiced class-A amp. I was thanked for playing some sweet cuts off the XX’s album, and I thanked them for making it sound great.

“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.

In a show dominated by forward-racing technologies and innovative solutions to complement the ways in which we consume media, DeVore Fidelity and Tone Imports continue to find inspiration in old-fashioned pleasures...
