Tube amp for KEF Reference 3s


Hi Everyone,

  Long time Audiogoner but this is my first post here.  I am looking for some suggestions regarding amplification for my KEF Reference 3s.  Currently I have a Modwright KWI 200 with built-in DAC which I like a lot, but wonder if the KEFs would benefit from a high-quality tube amp.  I would like to go for a high-end amp like a VAC or Air Tight but would prefer "testing the waters" first by trying a tube amp in my system.  I primarily listen to Tidal streamed through a Audalic Aries into the Modwright and analog through a VPI Traveler/Musical Surroundings Nova II.  I have a small listing area (my office) which is approximately 12 x 16 and I have some GIK acoustic panels in the corners and along my back wall.  If anyone has suggestions as to a "low-priced" tube amp that might give the KEFs a somewhat warmer sound I'd be willing to purchase used and then move up the chain to a higher-end amp if things work out.  Thanks in advance for your advice.

@mountainsong, if I recall you own Ref 1s.  I think those should give you a pretty good idea of how the Ref 3s would sound in your space - just "more" of what you already have.
I think KEF ref in general sounds better with SS amps VS tubes.
It will not occur to me tubes with them.
I am getting into the ref 3 soon. Ill use my H30. Second to none. Just my opinion.
I really like the Leben cs600.  I heard them with a few pairs of Devores and Harbeths speakers and they sounded great.  I owned the Rogue Cronus Magnum 2 which sounded great in that price range.  What's your price range? 
Thanks  nycjlee.  It is interesting that the dealer from whom I purchased the Ref 3s thought that tube amps are a better match for the KEFs, but he sells VAC so perhaps in that price range he is correct.  I have always been a SS guy mostly out of convenience but thought that the KEFs, given their neutral tone, might benefit from tubes.  

My price range fortunately is not limited, but before I delve into an expensive amp (SS or tube) north of 10k I thought a less expensive trial of a tube amp with a new DAC (my Modwright has the built-in DAC) made sense.  For now I'd like to keep it in the 2-3k range new or used.
