I have an AVP, BPA3, ML334...driving Martin Logans... originally I purchased the AVP struggling with the same question you pose...and agree with the first post about the Lexicon...I've never heard the EAD...I'm going to audition the Classe SSP75 this week...it's gotten rave reviews from Stereophile, and a local Martin Logan dealer hanndles it...interesting to see how it works with the proceed/levinson stuff
