Peachtree was showing off its new iNova integrated DAC/preamp/amplifier, the replacement for their best-selling Nova. The iNova upgrades some parts from its predecessor including better capacitors, a 24-bit/96kHz USB input and an upgraded iPod dock. The amp is rated at 80Wpc and will sell for $1799.
The iNova was hooked up to the brand new Aerial 7T speakers, which employ some major cosmetic, and structural changes from previous Aerial speakers. The 7T ($9850/pair) is a three-way loudspeaker, nominally rated at 4 ohms and 89dB sensitivity. The finish on the cabinet, made from MDF bent to shape, was excellent. (Though the enclosures are made in China, the speakers are manufactured in Aerial’s Massachussetts facility.) Playing files from a server to the iNova, Aerial 7T sounded huge and clear with fantastic bass extension and articulation.
I was impressed by the fact that the Peachtree was able to drive these speakers with such scale and authority.
Sonneteer, a UK audio company, was showing off its new Morpheus Music Center ($4000), an integrated amplifier, DAC, and control center for streaming audio. The amplifier section is rated at 50Wpc and will stream music via WiFi or Ethernet, play Internet radio, and USB input. The Morpheus also has three analog inputs and one analog output so it can send signal to an external power amplifier or subwoofer. Standing by his creation is Sonneteer’s Haider Bahrani.
Parasound showed off the guts of their new Halo JC 3 Phono Stage ($2300) in the same room as the butt-kicking Atlantic Technology AT-1 loudspeakers. Designed by John Curl, the JC 3’s signal/noise ratio is a high 83dB for moving-magnet cartridges and 73dB for moving-coils. The RIAA curve is said to be accurate to within ±0.1dB and the units are currently shipping. Michael Fremer reviews the JC 3 in the March issue of Stereophile.
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.
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.
New from E.A.R. USA is the V12 integrated amplifier ($9595), one of the prettier looking and sounding pieces I heard at CES. Many may remember E.A.R.’s V20 integrated, to which the V12 owes some inspiration. The V12’s visual design is also inspired by a Jaguar V12 engine, minus the motor oil stains. The V12 was designed by Tim de Paravicini and uses six EL84 tubes per channel. It puts our 50Wpc in triode mode. The sound, driving Marten speakers and using Jorma cables, was airy yet colorful.
Jason Victor Serinus elaborates on the Jorma cables: Jorma Koski, who owns Jorma Design of Sweden, designs all of his cables. When asked what makes them unique, he initially replied, “It’s the best cables in the world, except that everybody says that.”
Conrad-Johnson introduced their new ET5 line stage preamplifier. According Bill Conrad and Lew Johnson, the ET5 is a scaled-down version of the GAT preamp (the silk-screening you see here labeling the ET5 as a GAT is an error). The ET5 shares all of the same parts as the GAT but is a stereo design instead of the GAT’s dual-mono layout. The ET5 uses Vishay resistors, CJD Teflon capacitors, gold plated OFC I/O connectors and vibration-isolated printed circuit boards for the gain circuit. The ET5 ships this month and will cost $9500.
“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.
Like the Marten room, the Engström & Engström room also played the new large Coltrane 2 speakers by Marten of Sweden. This year, the Coltrane 2 speakers met The Lars Type 2 monoblock amplifiers ($60,000/pair), which each use two 300B tubes and deliver 36Wpc.
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 distortion0.05% 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.
