I reluctantly sold off my TriVista several years ago as it could not playback high Rez files. You either had to downsample to 44.1 (in Roon or your playback software), or only choose 16 bit CD quality versions. The 24/196khz capability of the TriVista DAC I believe refers to the TriVista upsampling of a 16bit file - the TriVista can’t natively play 24/192 files, or MQA. I wanted high Rez support as I use Roon.
shame, as the DAC was excellent even with its age. Very well built and long tube life.
