Is it my streamer or does Audirvana sounds better?

Dear members,

I really need some help here with my digital front end. I tried 3 different streamers in the past 2 years( Bluesound node icon, hifi rose and Eversolo T8) and everytime I keep going back to Audirvana via my MacBook. Why is that if everyone keep saying ditch your computer? I am only using my MacBook for streaming audio

only( not for personal use) connected to my Garlubidor divinity r2r dac. The rest of my system is McIntosh C2600 preamp and McIntosh Mc452 amp. No matter what I do Audirvana sounds better to my ears. Is it my rusty ears? Is it my streamers? Any comment and idea will be highly appreciated.
