tube pre-amp for active monitors

@mrdecibel 
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.

Most active speakers have ridiculously low input impedance and many/most tube preamps will not drive them properly, solid state preamps should have no trouble.

QUOTE: " Airpulse Model 1: The input impedance is quite low, so do check that the source is happy with such a loading. Valve pre-amp use is presently contraindicated by that low 2.5kohm value for the RCA input sockets"

@georgehifi
I am using the XLR balanced inputs on the Air Pulse monitors

I wonder if there is a simple stereo tube buffer I can fit between DAC and monitors?
