So the saga is a headphone amp and preamp?

No, its only a preamp.  
 
Signal from DAC to Saga to HP amp.  Use the Saga as volume control and multiple input switch to amp of choice...

Hi! Is it just on mine or is there a relay click on powering off too? Like 4 clicks on off?
 

 
The relay engages when you turn on your JOT, and disengages when you turn it off. It's a switch, that is it's function.

Ahhh!! That makes sense. The manual said the pop is expected when turning on, but no explanation about sound when turning off.
Thanks for the explanation :D

There are a lot more than one or two relays... I thought I heard the same thing and looked at the circuit board and I think there are actually 8 relays!
 

 
I think the green ones all come on with the power switch, the 4 simultaneous clicks sound like a faint sizzling or crackling at the same moment you turn on the power.
 
The orange and blue relays are for balanced and SE headphone out, those are delayed and one of each trigger at the same time, one channel at a time.
 
When you power off it's the opposite, the orange and blue headphone relays all turn off instantly with the click of the power switch, the green ones turn off one by one (4 clicks) as the capacitors discharge.
 
 
You might think all these mechanical switches won't be reliable but each should be rated for at least 1mil cycles.
Even if you power cycle the Jot 10x a day they're good for 274 years!

Makes me smile when I look back to 2014 re July of 2011:

"some reasons why we didn’t want to use relays (most of all, contact degradation from outgassing, which NwAvGuy dismissed out of hand, although it is clearly present on the data sheet.)"
 
and look at the number of relays in the current line up.

Thanks for the information guys!
I really appreciate it.
 
I hope Schiit read this thread and write that "turning off also pop (several times)" in their next generation's product's manual so dumbasses like me would understand them without having to ask around.
