The Venetian Hotel was home to high-end audio and home theater demonstrations at CES 2009. Many of the exhibitors were mainstream manufacturers and others were names most people have never heard. One of the best demonstrations was Gemme Audio, based in Montreal, Canada. They were demonstrating their new Phenix Green Gem speaker, a three-piece system with a 12 cubic foot bass enclosure and two Soprano satellite speakers. The goal of the Green Gem system is to create a three-dimensional reproduction of the original recording, where scale, width, perspectives and movement are all conveyed to the listener.

The Green Gem bass enclosure houses two 15-inch drivers. Each driver has a very short 6 mm excursion, but barely moves even under demanding low bass musical content. According to Gemme, the absence of movement translates into ultra-low distortion and high dynamic capacity. Each Soprano cabinet houses two drivers in a sealed enclosure: a 6-inch low mass midrange driver and an Alnico powered horn loaded ring radiator tweeter with output above 30kHz.

The system sounded outstanding with beautifully open midrange and solid, deep bass with extraordinary extension. The beautiful craftsmanship of the enclosures is as impressive as the sound quality of the system. The Gemme Audio system is certainly not for everyone, but is audio at its finest. Suggested retail price starts at $37,500 and the model in the photo is $50,000. Each system is hand made to order.

The Gemme Audio suite at the Venetian featured amplifiers and pre-amplifiers from Angelis Labor, a Canadian manufacturer. The stereo demonstrations used the Araton Monoblock vacuum tube amps with 7-watts per channel and the Sophia dual-mono pre-amplifier.

I was invited to attend a demonstration by Gemme Audio, a veryhigh-end audio manufacturer from Montreal, Canada. Among the components shown in the suite was the Angelis Labor Gabriel Turntable, designed for the serious vinyl enthusiast. The Gabriel is a magnetic suspension record player equipped with a base that can accept up to four tone arms. The materials used include aluminum, bronze and stainless steel. The turntable system is composed of three parts - the table and base for one to four arms, the 13-inch arm and the cartridge. The price ranges from $27,000 to $64,000 depending on the number of tone arms purchased.
