I had a Lampi L4, G4 and now I've a two box level 7. Lampi dacs are wonderful. I've never heard AMR dac but the person who bought my L4-G4, used to have AMR and Berkeley Alpha 1 and was not entirely happy with them. After he got the L4-G4, he said that the Lampi is truly the best he is yet to hear.
I've bought my L4 from Fred and L7 from Rob. They provide superb customer support.
