El Capitan vs. High Sierra

Hi I have a question regarding different mac os vs sound quality. Ive been using high sierra and the latest audirvana, but recently has moved back to el capitan and latest audirvana running integer mode 1.

Between the two OS, which one do you think should have the best SQ? I feel like El Capitan running Integer Mode 1 sounds more “live” but less deep chewy bass compared to when I was running on High Sierra.

Hope to hear some details from anyine here regarding this matter. Thank you.
