Bringing Out The Sound Quality of Streaming
Digital audio signals from your PC, music server, CD or Blu-ray can be sent to the CMA Twelve via AES, SPDIF, Optical or USB. The core patented technologies of Current Mode Amplification, True DSD and 3x Clock Asynchronous Transmission allow the CMA Twelve to offer outstanding performance from its DAC and pre-amplifier. The specially designed ADJ/FIX switch is used to match with power amplifiers and active speakers.
Questyle Genes Of "Specialty"
The elegant lines and laser etched text for status and volume echo the professional “genes” of the Questyle family. Serious thought for every detail is revealed with the amber glow of each LED indicator against the black or gold, sandblasted chassis.
Mechanical vibration will affect audio signal processing and the resulting sound. To avoid resonance, the CMA Twelve chassis is formed from 10mm-thick aircraft-grade Aluminum 6063, with high precision machining techniques of ±0.02mm.
