With my setup (Lumin U1 to Singxer SU-1 to Spring), I observed the following when changing tracks involving the DSD format:
 
Programmed, clicks heard
DSD to DSD    No
PCM to DSD    No
DSD to PCM    Yes
 
Manual, clicks heard
DSD to DSD    Yes
PCM to DSD    No
DSD to PCM    Yes
 
Very odd indeed.

  "Programmed, clicks heard"   "Manual, clicks heard"

As a kid, I rode the short bus to school.  So I don't understand what you mean by programmed and manual?  Since I'm not familiar with your Lumin, maybe you could explain that a little more.

Some DACs have split second delay when playing DSD to eliminate the pops or clicks. If I am not mistaken, this was explained in the Mojo thread.

I don't own any DSD files. I should have mentioned that this is happening in NOS/PCM mode when switching to/from different sample rates either with/without using a DDC in front of the Spring with a USB/Toslink connection.
 
I'm trying to eliminate the noise by adjusting the one or more of the options in the "Setting" menu in JRiver.

That short bus is filling up, because here comes another passenger. lol

Lumin DS plays tracks via an app on iPad. By programmed, I mean pre-selecting a no. of tracks and let them play in the order selected. Manual means I jump between tracks on the selected list.

Oh that's odd. I don't use Jriver so I do not know if it is in the settings of Jriver but with Foobar I don't get any pops o clicks when playing PCM in NOS mode. However, I rarely use PC/Foobar anymore, my Soundaware D100 Pro is my main transport which is superb in many ways.
 
I hope you can troubleshoot your pop issue. Good luck.

Thank you.
I'm working on it.

Adjusting the setting in JRiver has gotten me no where.
 
So, using iTunes (Built-in Core Audio Output) I found there is no noise issues with the Spring changing between sample rates at all. But , it's also not bit perfect.
 
Introducing Bitperfect software to iTunes using the (Spring-xCore Audio Output) I have the same exact noise issue I have using JRivers software (Spring-core audio output). 
 
This isn't the end of the world, but I would rather not have this noise between changing sample rates, and again, it's occasional and very soft. One thing I will says that my Spring DAC has well over 500hrs and just continues to sound incredible. So much so, that for me, It has changed the entire musical presentation and the way I feel about the SQ of my 009/BHSE in a way I never could have imagined it would. So I am 100% satisfied with my purchase regardless.

It SU-1 does. I and my friend as well, we both have Sigxer and both makes clicks.

Since a lot of Holo Spring owners also use the Singxer SU-1, can I ask WHY the clicks/pops seem louder with SU-1 than without?

Cannot agree more with you in your last paragraph.

ive shortlisted holo audio level 1, gunj multibit and metrum musette to purchase early april. im leaning towards holo lvl 1 but im worried the 2.5v rms out from the spring dac maybe too much for my small earmaxpro tube amp. i was using a modi multibit before at 2v out. any advice here please. for eg is 2.5v too hot for my amp here or am i worrying about nothing as some cd players output 2.5v too. spec sheet for amp includes cd players as an ok source. is the spring dac overkill for tidal lossless 16//44.1 and tidal mqa up to 96khz? both pcm.

 

[joseph69]

I've been listening to sample rates ranging between 44.1 to 352.8 for the past 3hrs and not once have I heard a single pop/click while changing sample rates after going nuts yesterday trying to tweak JRiver to correct this issue to no avail.

@musickid Holo dac does not support MQA

@musickid Holo dac does not support MQA

It doesn't matter in this case, it supports MQA just as well as the Musette and the Gungnir MB.  If he's playing through Tidal, the software can unfold.
 
As to your question, 2.5v should not be an issue, it will only affect your gain.  If you normally turn the volume up past 9 o'clock or so, you should be fine.
