SUT's -Looking for one with some meat on the bones

I have Spendor D-7 speakers, with all tubes in my system.  The Spendor's are a little threadbare in the upper mids thru the lower highs in my listening room and I was trying to find a SUT with a little meat on the bones.  My wife runs from the room when I try to spin any LP's.  

  I am using a VPI Classic 3 Signature with a HANA SL cartridge.  I bought the Spendor's solely based on internet reviews, but am beginning to wish I had not.  I have never really cottoned to digital music and these speakers seem to go after that type of sound.   I am a lover of British speakers since the 70's, but these have zero relationship to what made me a fan of the UK sound.  

  Not trying to find a fat bloated sound, but very much miss the sweetness of acoustic instrument, string and vocals.  I may be suffering from oldtimers disease.  Analytical modern sound is not my idea of musical enjoyment I am afraid.
