Audio Research LS/Ref or Primaluna EVO Preamp

Currently I own a LS26 and thinking up upgrading. My amp is a Ref 110 so usually makes sense to stay with the same company. However, after speaking with a few dealers they are saying the Primaluna EVO 400 is kicking the pants off even Ref series of ARC.  I am not talking the higher end of the Ref series.  My shortlist I have been considering is a LS27, LS28 or Ref 3. One thing I like about ARC is they hold their resale value very well. A new EVO 400 xlr is $4699 but one dealer (won't mention) offered for $3900.  I also like the gain function of the LS26 for my phono stage but it isn't a huge issue I don't guess. My phono preamp is a Manley Chinook SE MkII and I am using it on 65db gain for my Dynavector 20x2L.  Has anyone owned or know much about the PL EVO 400 or is it wiser to stay in the ARC family? Thank you in advance  :)
