Questyle CMA400i DAC/Headphone Amplifier ReviewThe Questyle CM400i proves that neutrality really works when it comes to an all in one desktop device. One that works well with sensitive IEM's all the way up to full size planar magnetic headphones.
- May sound clinical to some
- No analogue inputs
Aesthetics and Build Quality:The CMA400i is a sleek, matte black DAC/Amp which looks very professional and understated. There are orange LED's on the front along with the outputs and volume knob; the inputs are on the back. It looks superb, but if you want to change the looks up a little you can buy an optional clear top cover to show off the internals. You can also get an optional desk stand that stands the CMA400i upright to save space. The CMA400i has a solid CNC machined aluminium shell and feels extremly well built. All the connectors are solid, the buttons precise and the volume control is super smooth. Questyle have made a superbly built unit here, with no flaws in the finish whatsoever.
Features:The CMA400i is a DAC/Amp, and does not have any analogue inputs, for that you will need the CMA600i which offers a pair of RCA analogue inputs. The CMA400i has 2 coaxial inputs, 1 optical input and a USB input, so it can be used with a wide range of devices. On the back you have outputs that can be used as line-outputs to an external amplifier or pre-amp output to powered speakers. You get a pair of balanced XLR outputs and a pair of RCA outputs, along with a spdif digital output (USB to spdif converter use). On the front you have the 4-pin balanced XLR output, a standard 6.3mm singled ended output and a 2.5mm balanced output. This covers the most common single ended and balanced connectors. You have the volume knob and also 2 buttons, one to switch between inputs and one to switch between Amp mode (for headphone and pre-amp use), or DAC mode (DAC mode switches the outputs on the back to line-outputs). On the bottom you have gain switches, for standard or low gain, this means it can be used with a wide variety of headphones and IEM's (standard is roghly 2.47x and low is roughly 1.1x)
