Help in streaming for Devialet 120

[K4680]

Hello,

My humble setup is Devialet 120 with Salk speakers ( Silk Tower).  Devialet firmware  I am using is 7.1.3.
I used to play songs from Tidal or local flac/wav files. While playing I used to connect my laptop with ethernet cable ( disable wifi assuming that it will reduce noise)  and I use a Cat6 ethernet cable from router to Devialet 120.
While playing from Tidal with some songs there was crackling sound and I stopped using this method   
I use to play from Oppo using spdif connection to Devialet and it worked well but felt sound quality is not up to mark especially while using Tidal .

Now to solve this issue I was thinking of getting Roon and install Roon core on my laptop ( I dont use it for any other purpose) and use Ethernet connection to Devialet 120 from router.Will this help in fixing crackling issue and have good sound quality?
I read little bit about Roon's implementation of Devialet AIR

Another question I have is does quality of the machine where roon (core) is installed matter  lot or  depends only on Devialets roon endpoint implementation?  Now my Devialet looks like old and I dont see expert models on Devialet website anymore. I assume they dont provide new firmware for Expert models.

Please let me know . 

Thanks in advance
