I'm having great results with a MacCormack DNA 0.5 revised to Platinum by SMC Audio. I have also tried (& enjoyed)a Dared VP-300B SET amp (runs out of oomph, but has that SET magic).
There was a recent thread on tube amps with the Ref 3's...
I've heard different opinions, but a lot of folks like the Gallo Ref SA (you don't specify, but I assume you are talking about the main or "full range" amp).
I also really like my Isorock GR stands.
happy listening,
