tube pre-amp for active monitors


I have Airpulse Model 1(A200) active monitors currently fed by MacBook Pro > Tidal > Wyred4Sound Re-Clocker > SMSL SU8 > balanced XLR out. I wonder if a tube preamp might yield some gains.... anything not-expensive that might fit the bill? Looking for a bit more enveloping soundstage....

Have you tried various positions of the speakers ? Are they close to a wall, on a desk, or are they on stands, away from reflective surfaces ? Forget an inexpensive preamp, whether tube or ss, as it is not needed.

I was thinking along the same lines but thought that a tube might give up some majik for the ribbon tweeters. I currently have the monitors toed in about a foot in front of me noggin. I need to take the room or of the sound field as it is long, narrow and ask hard surfaces.
" The last time I looked the tube Freya was $899. Read! "
@yogiboy: You are correct about the $899 for a Freya+.
My suggestion is on topic for an " idea " for the write up and video which coincidentally / timely is covered by my darko.audio reference.
By the way well very well done concise and informative.
The topic is " tube pre-amp for active monitors ".
Schiit also has lower priced pre-amps.
But the reference was not about Schiit Gear so much as the topic of discussion.
Sound.
