ATI (Amplifier Technologies, Inc.) of Montebello, CA, who also owns Theta Digital, were blowing minds with the nine channels of bass produced by the combination of their American Muscle AT6002 Morris Kessler Signature Limited Edition Stereo Signature Amplifier ($3995), which outputs 300Wpc into 8 ohms and is available in 2- through 7-channel versions; the finally released and revised Theta Prometheus monoblock amplifiers ($12,000/pair); the well-known, upgraded Theta Casablanca IV; and California Audio Technology loudspeakers.

Rogers High Fidelity's New York-manufactured, aerospace engineering-based system, which included the just-launched PA-1A six-tube phono preamplifier ($7100) (pictured on the right) and EHF-200MK2 KT150-based, 112Wpc integrated amplifier ($15,000), delivered extremely quiet, beautifully warm and lovely sound with Shunyata power conditioning, Kimber Kable, and Davone Grande loudspeakers. The two Rogers pieces also looked fabulous.

Gideon Schwartz of AudioArts NYC assembled an extremely fast system that delivered maximum color without any of the harsh, irritating edge that I encountered on many systems, both tube and solid-state, at CES. On Salvatore Accardo's well-worn Diabolicus in Musica LP of Paganini's solo violin music, as well as on a CD by the Musicians of the Nile, I was deeply impressed by the upward extension of the tone and the system's willingness to bathe music with the light it deserves. If the system wanted for the last iota of bass impact and clear delineation of low-lying lines, it nonetheless handled bass with a finesse that few hotel room set-ups offered, especially in the case of large loudspeakers sandwiched into small spaces.

Resolution Audio has yet to name or price its new 100W monoblock amplifiers, due in May, but they may come in around $9000/pair. Their push-pull design is licensed from English engineer Denis Morecroft. Build is distinguished by custom T-network caps and, in the company's words, "crazy careful attention to detail."
