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

@wrm57,
The Music First is a TVC and is not really a passive.
Can you please let me know what you "lost" in sound, when you introduced the Music First in your system, compared to the VAC Phi Beta? How would you compare the Music First Vs Bent Audio AVC?
@milpai

Sorry for the delay in responding. I just noticed your post. First, I've never owned a Music First, only listened to a friend's in my system. I did not mean to imply that anything was lost in moving from the MF to the Vac. Rather, as I recall, the MF was more similar to the Vac than I expected, and different from the Bent in the same ways the Vac is, as I described above.
