ARC LS26/27 vs BAT VK31SE

Does the ARC LS 26/27 have a more tube-like sound than the BAT in general?  What about soundstage, sense of attack, tonality, bass, etc...?

I recently purchased an LS 26 for my bedroom system.  It replaced a Jolida Fusion and was a big improvement, more detail and dynamics and a very noticeable improvement in the bass region.  I've been wanting to swap it out with my Modwright LS 100 in my main system to see how it sounds there, but haven't had time to do so yet.  The LS 27 is supposed to be even better than the LS 27.  I would not describe the LS 26 as having an overly "tube-like" sound.  Soundstage is a little hard to describe as it's in a small room, but I get a sense of the music being kind of "everywhere" with the LS 26.

No experience with the BAT.

I've owned the LS26 and I agree with @big_greg in that it's not a "tubey" preamp.  It's very close to a good SS preamp with a hint of tube warmth.  In my experience I was able to get very similar results from a Levinson 326S.

Can't speak to the BAT or LS27.

Thanks for the information guys. Wondering whether it's worth it to switch to a ARC preamp. The LS 26/27 series is in my price range.
