CES 2018

Andrew Jones's first active speaker, the tri-amped Argo Series B51 ($2000/pair), offers 250W of class-AB power in the form of a 150W AB amplifier for the woofer, 70W AB amp for the midrange, and 30W class-A amp for the tweeter. The B51s can be used either wired or wirelessly, but need an external DAC, DAC-equipped server, or other device to produce sound from digital.

Paired with the same Theta Gen. VIII DAC/preamp ($15,995)/Theta Compli Blu transport ($3995) combo and VPI Avenger reference turntable ($20,000) as in the SAE room, but with a TR phono cartridge ($7000) replacing the Zu, this room showcased CAT's brand new MBX 1250.2 FD XPR twin monoblock amplifier ($30,000), which outputs 1250Wpc in to 4 ohms, and MBX 320.2 FD ($10,000) twin monoblock amplifier, which outputs 320W into 8 ohms. The amps were driving a bi-amped pair of CAT loudspeakers, specifically voiced for this hotel room, which consisted of CAT MBX 900 Trinity satellites resting upon MBX Miramar subwoofers ($100,000/pair for all). Analog crossovers were employed, and the subs were dialed-in through a CAT MBX DSP8x8 digital signal processor ($15,000).

Etymotic's Albert Arends was showing four models of the company's earphones. The Etymotic ER3SE (Studio Edition—$179) has a flatter response than the ER3XR (Extended Response—$179), which has "a bit of a bass lift" in the 100Hz-1kHz region. One major difference between these models and the higher level ER4 SR (Studio Reference—$349) and ER4XR (Extended Response—$349) is that only the latter are channel-matched to within 1dB.

This is hands down my favorite new "Concept of Show". Here is a small powered speaker coming out of Sweden that has some surprising tricks up its sleeve. You can see from the photo that these are not big speakers, but they have a unique method of overcoming this limitation.

Richard Vandersteen, hailing from Hanford, California, was on hand to show off his new creation, the M5-HPA monoblock amplifier. Vandersteen notes that this is a high-pass amplifier, not intended to go full-range, for a system that would also include a subwoofer. The selectable high pass settings are 20Hz, 40Hz, 80Hz, 100Hz or 200Hz. The 80 and 100 Hz settings are optimized to work with Vandersteen subwoofers.

The wireless version of Audioengine's highly regarded A5+ loudspeakers ($499/pair in black or white, $569 in bamboo) uses aptX HD Bluetooth to transmit signals up to 24/48…

Paul Barton of PSB was on hand to demonstrate the RoomFeel technology he uses in his headphones. "Headphone listeners listen to recorded music that was designed to be heard in a room," he said. Therefore, his RoomFeel technology adds a simulated room response to music.
