DAC Simaudio MOON 300D
MOON 300D is not very specific power (power supply 10 V*A and the total capacity of the filter capacitors in the 13 200 uF), but it has as many as eight steps Input voltage adjustable. Digital stream inlet exposed eight times oversampling for converter Burr-Brown PCM1793, a proprietary patented jitter reduction circuit ensures accurate signal processing. Since the DAC is assembled on a balanced scheme, its connection to the amplifier for balanced output provides the best values of technical parameters. Input USB interface allows you to send the old version of the signal from the computer with 16-bit resolution and a maximum sampling rate of 48 kHz.
Small block in half the normal width deprived screen, front there are only two symmetrically spaced around the edges of the button - Standby and input selector, and the columns of LEDs - left, marking the current sampling rate, and the right which will highlight the selected input. Symptoms saving traced in the circuit group in simple short terminals and arrangement of digital inputs abutting each other. However, the analog output connectors are spaced so far as the small size of the housing. Console is not supplied. Manufacturer separately notes that it is desirable to keep the device permanently connected to the network, otherwise the output of the maximum sound level will take considerable time, up to several hours.
Given that the pair Simaudio MOON 300D and 650D - it's actually a relatively complete downgrade of the senior model, we, of course, first of all it was interesting to compare the changes in the sound when using the DAC 300D. It turned out that playing different music tracks became more simple and linear, without the luxury pearl, mauve contours and gentility older brother. Also departed soft detail and plasticity of sound. However, at the same time, it became quite obvious that the devices - relatives by origin and general character, on the approach to the interpretation of the music. It is recognized as a soft and laid back style, a little pensive and completely devoid of fussiness, and built very strict rhythm, attention to detail micro-rithm, neat and precise flute, violin, keystrokes. In explicit contrast to the stronger older models 300D clearly preferred moderate boiling passions and not too willingly practiced powerful orchestral shafts or polyphonic choir. Despite assurances from the manufacturer about even excessive power supply, in such fragments were pretty good noticeable compression and "hunching" sound, his care on the back burner. However, in cases where the DAC is not forced to play too dramatic and powerful things he pleased plastics and accurate rhythm sound, coupled with a good level of musicianship.
