Hey everyone! I got this DAC yesterday and have been playing around with it for a few hours. Am I really glad I checked the back of this amp before plugging it in! The sliders were set to 220V and not 110V. After searching for drivers I managed to get it working well with Foobar via Windows 10. I've gotten it to play DSD and all other resolution file types I've thrown at it. It is a fantastic sounding DAC, but there are a few issues I am having that may cause me to return it. Toslink does not work with 192khz files from my computer or my iBasso dx200. No matter what settings I put within the DAC, it will not play 192khz. (Meanwhile my SMSL SU-8 Version 2 plays 192khz via optical just fine.) I do not want to only depend on USB so I wonder if this DAC can even play 192khz via Toslink. I also cant seem to get DSD over PCM to work via optical either. Android (Galaxy Note 9 via USB) works well using USB Audio Player Pro and in other phone apps in general. However, I run into an odd issue. Whenever I play 192khz files, and I skip around within the song, or skip to the next track the songs severely glitch. The song slows down to about .25% percent speed, and then sounds like distorted 8-bit 1980's video-game music. Skipping around the track or even the album would give the same glitch. The only way to clear this is to exit the album. I can play any other high resolution PCM and I can't replicate this. The amplifier runs really warm, not hot, but close to it. Butter melting warm I'd describe it. I'm not sure if this is normal or not.
