Spendor D9, Proac D48R or Devore 0/93?

It should go without saying that you need to listen to some or all of these to find out for yourself whether you like the sound or not.  Other people's recommendations can only take you so far.  That said, my recommendation is to seek out some used Spendors from the Classic series such as the SP 1/2 or 2/3.  They offer a warm musical sound well suited to tubes and jazz.  I used a set of Spendor SP-100 speakers for over 15 years and have tremendous respect for their virtues.  I find them more natural than the Devore O/96 (haven't heard the 93).  The SP-100 is too big for your room which is why I am suggesting one of its smaller brothers.  My comments on the Spendors are made as a former owner since I sold mine recently.  I just hope I don't regret selling them.
