I have no experience with the Avalon Eidolon, I like a lot the Avalon Eidolon Diamonds, but mainly for classic music.
Since you listen mostly to jazz, blues and some rock and roll I would advise you to consider seriously the Proac D80 - I have owned Proac 5's and they were really good with this type of music and should sound very good with either of your amps - I preferred the sound of the Proacs with tubes, but I have read that a well know studio in Portugal has Proac with Krells.
