Does Lumin x1 needs a dac ? does a good dac will improve it ?

@azwill

Thanks for your precision .
What brand of passive switch box ?
I am supprised , the switch box , doesn’t add some coloration or restriction to the sound.

I have always though , the less between the source and amp, the better.

Which brand and model of interconnect do you use for your Lumin ?

I have once consider Goldpoint. as a switch box .

The sound may also depends on the upsampling ´ s level   you choose .

@azwill Hi and thanks a lot for your response !:)

I don't think that I still reached to 200 hours playing of my X1 . I think that approximately i used it for maximum 100 hours , not more. Its quiet new...

Don't understand me wrong, I'm quiet satisfied with my X1 and my system, I just felt that i can a bit improve it and I'm sure that when i reach to 200 hours and more it will be even better.

I'm still not using Roon, but I'm planning to use it in the near future. For mean time I'm using Tidal through lumin streaming application.

I using Plinius LAD CD preamp - is too old and i think that compared to my rest system he is simple, he is not good enough. I'm planning to buy in the next year , i think , a new  preamp of CAT (SL1 legend) , I'm sure that when ill buy it , it will defiantly improve the sound . mean time i will try using lumin as a preamp.

Thanks a lot man for your effort  in your response. 

@maxwave I'm using the X1 as my only source too. I have a CD player but i don't use it. I"m planing to buy a TT in the future , I love the special sound of records.

Thanks for all your responses.
