I’ve been listening to the Harmony for several days now, and between burn-in and playback sessions, I probably have well over 100 hours on the DAC. I like it very much and have little to add to the positive accounts in this thread about the sonics, other than to add that it puts out the best digital sound that I have ever heard in my setup.
But, I have experienced an issue with the “Track Info” display when playing CDs. While playing some discs, the track information will blink continuously. On a few other discs, this problem is intermittent. This does not seem to be a source issue, as it occurs with both my TEAC transport and an old Yamaha CD player that I am using to burn in the DAC. The great majority of CDs that I have played so far do not produce the problem.
I wrote to Weng Fai Hoh about this, and he replied that Laiv is working on a solution, that the problem seems to be confined to coax input, and that the blinking display can occasionally be resolved by changing to another track.
The blinking display is not a deal killer for me, the sound is far too enjoyable, and I simply turn off the display with the remote when it occurs. I tried the track change hack, and it does work sometimes. I do have to say that it is mildly annoying, and I hope a firmware upgrade will resolve it.
