The SMSL M9 is a high-fidelity USB DAC 32bit in the right line of the best sellerhref = "http://www.audiophonics.com/en/dac-sans-volume/smsl-m8-dac-usb-es9018k2m-32bit-384khz-dsd-xmos-p-9723.html" target = "_ blank" >SMSL M8. This compact DAC in a machined CNC aluminum case integrates the best of current technology on a single circuit reducing the maximum welding contacts.
A double DAC 32bit:
This DAC includes two AK4490 converters. The result is a lower crosstalk taking advantage of true High Definition, increased dynamics. It is therefore able to support PCM audio files up to 32bit 768kHz as well as DSD64, DSD128 and DSD512 files.
Fully lined design:
The M9 SMSL is designed to offer the maximum separation between the left and right channels from analog digital conversion. This CAD therefore has two CADs AK4490EQ, 5 operational amplifiers OPA 1612of high precision. The audio result is of real acuity in terms of sound accuracy. This DAC features on its CINCH RCA a variable output controlled by two analog volume controls PGA2311.
One USB hrange:
The USB digital input of the SMSL M9 includes the latest chip generation XMOS 32bit XCORE 200. The M9 SMSL has a computing power that far exceeds the scope of digital audio with more than 1000 Mipson an instruction structureDSP 64bit.
The M9 SMSL offers 32 bit audio playback capability rarely achieved in this product range. The conventional digital part on SPDIF optical and coaxial asynchronous input also includes a high quality processing.
The input interface on DIR CS8422 with FIFOincludes a high-quality ASRC system coupled with two separate very low drift clocks. This audio converter incorporates the latest generation of LDO T controllersI TPS65131sure8 levels of regulation . Thus the background noise is retreated to its lowest level to reach the dynamic that demands the 32bit High Definition.
A very high level balanced headphone output:
This DAC now incorporates two amplifiers TPA 6120A2enabling the most demanding headsets, even at high impedance. So we take advantage of the high resolution of this exceptional DAC on a standard 6.35 jack output but also an output on 2.5mm jack type actually symmetrical .
A simple and readable interfacen 1.44 ":
Its quality display is an advantage providing a not inconsiderable comfort with regard to the source selection and the type of files being decoded. It allows you to configure the sound at your convenience via a selection of 4 different filtering modes including the famous Short Delay Slow Roll-Off. There are of course conventional DSD filters.
