Hi everyone,
I'm a new forum user (but I read it since a couple of years), I kindly beg your pardon in advance if I am posting an already discussed post and I ask your help because I'm looking for a decent (that is not extremely cheap but neither too expensive) external USB soundcard with optical S/PDIF input and outputs. I don't care of analog RCA inputs and outputs (so no need for hi-end DAC and ADCs), only optical in and out. It is for Hi-Fi stereo (L/R) only environment, no 5.1 or 7.1 or Dolby DTS interest, just PCM coding in/out for Hi-Fi purposes, at minimum 48kHz.
My goal is to "play" with PC-based room correction DSP software (like Equalizer APO with linear-phase EQ like QRange) to correct the acoustics of my living room (I already made a full acoustic treatment and I want to add DSP correction capabilities too).
For this purpose I am currently using a cheap (but pretty decent, at list for test purposes, not for definitive use) USB soundcard Behringer UCA-222 but it has only S/PDIF out, and I would like to avoid the ADC conversion... ideally I would like to perform the DSP EQ in digital domain (digital source optical out --> soundcard S/PDIF input --> PC-based DSP --> soundcard S/PDIF out --> built-in amplifier DAC via S/PDIF optical in) in order to make only the final DAC conversion through the hi-end DAC built into my Marantz PM6007 integrated amplifier.
I found only cheap soundcards (on AliExpress and Amazon) based on the C-Media CM6206-LX chipset but in most of them the S/PDIF in-out is passthrough only (so not useful for DSP purposes).
Thanks for everyone who will help.
