Meier Audio Corda PCSTEP USB-DAC Portable Headphone Amplifier Black
Description
- Measures: 8.9 x 6.6 x 2.2 cm / Weight without battery: 115 gr. / Supply voltage: 6 .. (9) .. 15 Volts DC / Mean current uptake: 28 mA
- Discrete volume control. Typical stepsize 1.5 dB, 31 steps. / Maximal amplification: -2 / 14 dB (low/high gain) / Input impedance: 120 / 19 kOhm / Output impedance: < 1 Ohm
- The unit runs from a single 9V battery, 5V USB-power, or an external powersupply (with upto 15V). Internally the supply voltage is doubled to increase driving capacity. External noise is removed by extensive LC-filtering of the supply voltage. The total buffer capacity is 1700 uF to lower the effective battery impedance. For amplification two single OPA209 opamps are used for maximal sonic performance.(No dual or quad-opamps!)
- The USB-DAC is based on the PCM2702 DAC-chip by Burr-Brown. / Resolution USB: 16 bit / Sampling frequencies USB: 32, 44, 48 kHz / The 3.5 mm sockets are silver-plated.
- Inside the signal path only metal-resistors and high-quality film-capacitors are used (polypropylene). The enclosure is made entirely of aluminium. Accessories: 2 mini-mini interconnects (goldplated) ,USB-cable ,tool to open the amp
The PCSTEP is a portable amplifier that, in addition to its analog input, also has a built-in USB-DAC (16bit/48kHz). When connected to the USB-port of your PC it will strongly improve on the sound that is provided by a standard quality soundcard. The amp has a discrete volume control (32 positions, two gain settings), resulting in a clean sound without any channel imbalances. With so many headphones, earphones, cables and headphone amps to choose from, it can help to know what to look for. Check out the website for reviews, comparisons, tips, specs and recommendations!

Transparent, powerful, plug n play, bargain
I can't praise this DAC/amp enough. Build quality is superb - all steel chassis, connections are tight , volume knob just right size and responsive. Power- huge, drives my 250ohm beyer dynamic dt770s easily. Sound- you can't hear it because it's transparent, EXACTLY what you need from a DAC/amp. I hear the character of my well known (200+ Hrs) headphones and recordings only. Grab this hidden audio gem and be confident that you don't need to audition it or spend hours reading comparison reviews. I got mine direct from the manufacturer, great transaction.
