If you enjoy the sound of your ARC, you won't really like the Benchmark IMO. I personally don't and prefer the sound of the ARC which is quite different. I would suggest you look at an Audio Aero Prima mk2 or mk3. They have a similar style to your ARC, and even the Carys, with the mk3 being a little smoother and the mk2 a little more dynamic. Either can be had in your price range. You will have a hard time going to a SS cd player after having owned a CD3 IMHO.
