Rega, Levinson or other Integrated for Avalon Eidelon Diamond

Looking for some feedback on an integrated amp search for my Avalon Eidelon Diamond's (87 dB efficiency). I found a Rega Osiris and a Mark Levinson 5805 in my price range. The 5805 has a phono section which is a plus. Both put out 250 watts in 4ohm, which I need to drive Eidelon's. These are both available locally to me, which is why I'm focusing on them. Open to having something shipped if it's a better fit for my speakers. I'm also open to separates that match within my $4500 but think I can get better value with an integrated system. Need to have a phono section within my budget. Thx.
