I'm considering replacing my passive preamp with a tubes. Is it worth it?

I would like to know if it would be worth it to trade my passive preamp for tube.  Would the change make a significant improvement?  

My setup:

Magnepan MG .7
Mod Squad Line Drive passive preamp
Bryston 4b-st amp
Rythmik f12 sub
Bluesound Node
Tidal streaming

My budget on a preamp would be $1k.  If the answer is "yes" then opinions would be welcomed.

thanks
