Nucleus+ clone question

I now have a Dell XPS with Roon loaded onto it and have an external SSD drive with my flac files. I also subscribe to Qobuz. 

For the last few weeks I've been having issues while streaming. The core constantly gets lost and oftentimes it takes a long time to go to the selected recording.

Would getting a clone Nucleus+ make the playback smooth, quick and hassle-free? And secondly, would the sound quality be improved?

Thanks.
