VAC’s most affordable and compact music solution is a full-integrated amplifier, with 85-watt/channel power amplifier, true triode tube line control amplifier, and triode moving magnet phono stage. Flexibility is ensured by standard remote control, home theater input, preamplifier outputs, and optional MC and balanced inputs. If sound quality and simplicity are the priorities, this exceptionally musical amplifier is the answer.
The T2 Transmitter can receive digital signal (through USB/coaxial/optical inputs) as well as analogue signal (via RCA terminals and converted to digital via the specific ADC circuit). No setup is necessary; easy operation design requires simply plugging in the power cord. The signal transmission is in 24bit/48KHz wireless digital precision. T2 adopts the famous FIFO cache technology and digital PLL technology and reduces jitter to undetectable level so as to ensure a purified high-end sound performance.
The R200 wireless amplifier is a 200W Mono block. It’s also the integration of wireless receiver, DAC and ICEpower amplifier. There is a switch on rear panel, to switch in between left and right channel. Two R200 amplifiers can use the same same T2 Transmitter.
5G wireless system is able to support more audio systems by adding only receiver. One T2 can support more than one receiver so you can add one more receiver to support a second audio system, or a third receiver to support three systems.
At the May 2014 Munich High-End Audio show, CMA800i was officially launched to international market. CMA800i is set as an integrated DAC, Headphone Amp and Pre-amplifier questing for most high-end sound quality.
Pre-Amplifier output is a specific feature for CMA800i. Many brands, when designing an all-in-one model, use the headphone amplifier circuit loop to support pre-amplifier function for the sake of cost. The CMA800i, which is concerned only with achieving the best sound performance, is designed with a totally independent pre-amplifier. Volume control adopts a ALPS27 potentiometer working in pure analog format, which supports remote control capabilities and it more suitable for supporting active speakers.
CMA800i is assembled with suitable high-end components like DALE military resistors, WIMA capacitors, Nichicon FG capacitors, customized Plitron Toroidal transformer, and Neutrik connectors. Aluminum chassis is specially CNC tooled into “mutual-bit” structure with a 10mm thickness cover, reducing the CMA800i natural resonance to lowest level. The feet are constructed of pure aluminum material tooled by CNC machine, and they can be switched to 3-feet triangle structure or 4-feet quad structure as per user’s preference.
CMA800R extends Questyle Audio’s outstanding Current Mode Amplification TM technology, providing 0.00038% ultra-low distortion, 650KHz wide frequency, 114dB signal-to-noise ratio. These parameters are far beyond any other existing headphone amplifiers can achieve. CMA800R is the world's first headphone amplifier that supports Mono Full Balance function.
What is Current Mode Amplification?
Current Mode Amplification means the amplification is processed in Current version, instead of Voltage version. It’s widely applied in the high-speed communication industry and video processing industry, but Questyle Audio uses its patented technology to apply it into the headphone amplifier. Current Mode Amplification also takes transistors as amplification components, but the amplification circuit loop is very different from that in voltage mode. In the whole closed-loop all the capacitors in between those transistors are working under ultra-low impedance so it can easily achieve large bandwidth and ultra low distortion.
