I am using Sonus Faber Guarneri Mementos with my MA7000 and the results are phenomenal. I would suggest looking for a used pair of these speakers or giving consideration to the newish Sonus Faber Cremona Auditor M's (The M's are better than the original Auditors) Properly set-up, the Auditor M's are unbelievable speakers and are well within the price range you have set.
Although these are stand mounted "monitor" type speakers, the imaging and soundstage are astronomical and the bass is 'full enough"
I am using a JL Audio F-112 sub with my Guarneri Mementos and together they equal supposedly full range speakers costing $50,000 or more.
