I am on a similar hunt, looking to change my Music First Baby reference passive, into an Audio Research Ref 75 power amp. I say looking, because I think the Passive will take some beating. I don't particularly like the Arc reference 3 pre, cetainly compared with the Music First.
As Sabai suggested, I was looking at the Audio Horizon. It has good reviews and an enthusiastic following on this site. It is by direct sale, so good value for money and is available for home audition. The makers offer a wide range of possible upgrades and balanced and RCA inputs and ouputs. It seems a no brainer to me.
