anyone have experience with both the Schiit Gungnir Multibit and PS Audio DirectStream

I've done some research and I've been told that  the relay click is used to switch between different "sample rates and bit depths".   So if you're listening to an album that was all recorded (digitally) identically, you will get no click.  If there is any difference, then you'll get the click.  I think you can also get the click is there is a short period of silence between the tracks (when streaming) that is not presented in the same format. 

this is correct - the clicking is pita...  bad when you have a playlist that has tracks of different types

There are certain transports, like the Cambridge, that if you put a playing disc in pause, the Gung clicks constantly until you resume play.  A design feature, I gather.

The only clicking I’ve heard is from the Bluesound Node for most but not all mp3s. Irregardless of DAC.
This made me convert them to #8 compressed .flac.

Clicks gone

Hi,
Didn't know there'd be so much comment on the Gumby's clicking (sometimes) between tracks. I'm a playlist listener, so I hear the click very often when changing tracks. This is what Schiit has to say about the clicking, from from the FAQ at the end of the Gungnir manual. Thanks again to all of your for your comments!

"Hey, this thing clicks between songs/between inputs/etc!
Yes, it does.
Care to explain why, smartass?
Sure. That’s the muting relay engaging when there’s no input. Many computer sources turn off the digital audio output between songs and when changing sampling rates. We went with a muting relay because it’s the best way to ensure there are no clicks or pops when the input is unlocked. But it does click a bit."
