I recently upgraded my Vivaldi DAC with the Apex board, and everything was going swimmingly until tonight. I usually listen to music with my Vivaldi Upsampler set to DXD, but tonight I thought I’d see what the upgraded unit sounds like with DSDX2. However, every time I tried to play something with the Upsampler set to DSDX2, the music either cut out after a couple of notes or didn’t play at all. This occurred whether I was streaming to the Upsampler via Mosaic or Roon. I was able to play 44.1K files upsampled all the way to DSD with no problem, but as soon as I went the last step to DSDX2, the music cut out again. I tried rebooting both the DAC and Upsamper, but that didn’t solve the problem.
Anyone else experience this glitch? I can’t say it’s due to the Apex upgrade, but I never had this problem before.
