CAS 2010

Towering Alan Dwight Hulsebus of Raven Design Studio was proud to show off the unusual skeleton of his Raven Ebb loudspeaker ($12,000/pair). Manufactured and designed in Camarillo, CA, the speaker includes a proprietary Raven ribbon and Focal drivers (including two rear-firing drivers to optimize room interactions), and is wired with Clarity cable. (Exhibitor Orca Design and Manufacturing distributes Focal in the US.) Claiming a frequency response of 40Hz–50kHz ±3dB, with a nominal impedance of 6 ohms and minimal impedance of 5 ohms, the 86dB-sensitive loudspeaker was paired with Superlative Audio's SSA-250 50Wpc amplifiers ($30,000/pair), Oppo BDP-83 SE player ($899), Benchmark DAC1 HDR DAC/preamp ($1799), and a host of Clarity cable.

Stereophile will be reporting live from the show starting July 30.

When I entered the Audio Note UK room, someone was in the midst of auditioning a CD of exotic Chinese instruments. The strings sounded beautiful, the highs lovely. On solo piano, the system had a very quiet, enticingly crystalline purity. Soprano Elly Ameling's voice sounded equally beautiful, the voice clear and radiant, even though her piano accompaniment was strangely bloated and over-emphasized. That was no doubt due to room problems that other exhibitors tried to tame with ASC Tube Traps.

The imposing Lotus Group Granada UB II loudspeaker ($125,000/pair), complete with an active crossover and Feastrex Type II field-coil driver, was sounding the best I've ever heard it. The system as a whole was a bit dark for my taste, but a track from Esperanza Spalding's new disc, Chamber Music Society, was just beautiful. Everyone in the room loved it.

Music Lovers Audio of Berkeley and San Francisco had the big and small of the Wadia line on display. When I entered the room, the Wadia 571 CD/digital preamp/DAC ($13,950) was on standby, and Wadia's diminutive 170 Transport iPod dock ($379) and 151 PowerDACMini ($1195) were doing the iPhone.

Given how good Wireworld's Platinum Eclipse cabling sounded with deHavilland and Glow electronics, I was delighted to encounter Wireworld's David Salz demming another Glow/Sonist system in the adjoining room. I'm sure Wireworld's Equinox 6 interconnects ($200/pair), Equinox 6 bi-wire speaker cables ($750/pair), Stratus power cords ($100/2m), and Matrix power strip ($120) were doing just fine. So, I expect, was the source, a Cambridge 550C CD player ($595). But the Glow 832 SET 7wpc stereo amplifier ($795) was challenged driving the 93dB-sensitive Sonist Recital 3 floorstanding loudspeakers. Things sounded okay with the volume turned down low, but when you invited singers to come out from behind the closet door and stand in front of you, the sound began to distort and fall apart. It takes an extremely efficient loudspeaker to enable those amplifiers to truly glow. To its everlasting credit, Wireworld's cabling did not mask the problems associated with the mismatch.
