Whats the difference between the black, new Syba Sonic and the old silver Syba Sonic?

I was looking at the new Syba Sonic but I’m not sure if the review of the older silver model also covers the new black model. I know that they have different amps but is it an upgrade over the previous version or not?

New Black Model

Old Silver Model

so in my possession I have

  • MH752 with the little DAC
  • SHP9500
  • Astro Mixamp Gen 1

My motherboard does not have an optical audio port so I cannot use the Astro Mixamp presets or dolby etc

My current setup is, whichever headphone I am using at the time, I plug into the MH752 DAC thing

should I be plugging something into the Astro Mixamp or no?

I was looking at the Syba Sonic DAC’s (the silver one and the newer black one) but am not sure either is needed to drive either headphone

my usage varies from serious gamer to casual gamer to media enjoyer.

any help appreciated
