Hi Papaya, what amplification are you using including source and cables.
I like ARC, I have owned allot of their product and enjoyed, their Aniv pre looks interesting and anyone whom I have communicated with who owns the Ref2 phono seems to be thoroughly enjoying it.
The Dart is going to be a different beast and if you have been voicing your set-up currently arround the Ref3 then I would think it would be a safer bet to stick with ARC which ever direction you go but in the end would be best to hear in your own set-up so you can deside for your self.
