I have been using my K22 successfully with an Audio GD DAC. The K22 has flac files on a SSD drive (ripped from CDs), and otherwise I stream using Roon / HQP / Qobuz. The AGD DAC is connected to the K22 by digital coaxial cable, and then the AGD feeds a preamp. .
I bought a Musical Fidelity TriVista 21 DAC at a good price. It’s several years old, but is capable of 24/192, which is what I’ve been limiting HQP to anyway to interface with the Audio GD. So I thought that replacing the AGD DAC with the MF DAC in my chain was essentially a like for like swap. I used the same digital coax cable from the K22 into the back of the MF. HQP Embedded remained limited to 24/192 in the Configuration screen, and otherwise I didn’t change anything in the settings. It’s just swapping one DAC for another one, but otherwise the chain remains the same.
But I cannot get the MF to lock onto the digital signal from the music server. I’ve spent a good couple of hours going through all the settings for the K22, then HQP, then Roon. I cannot for the life of me work out what the problem is. The front of the MF DAC has lights for 96 and 192, and you can toggle between these using a switch on the back of the DAC. However, neither makes a difference. There are two lights on the front of the DAC for each of the Coax and Optical inputs, and another light for Locked: these lights are supposed to stop flashing and be a steady blue colour when the DAC locks onto the digital signal. This is not happening. This applies whether I play flac files from the K22 hard drive, or when I try to stream from Roon.
I’m stumped. The previous owner of the DAC assures me that it was working fine. Any thoughts? What am I missing?
