Hi, I'm happy with my amplifier, speakers and CD player in my sig - however, i'm interested in the likes of the MCR510 or similar as I want to try out spotify , internet radio as sources or the use of HD format music player. I'm not looking for an amplifier built into the unit however as I don't really want to part with the Pioneer A30. Can anyone recommend a standard width box which has internet radio, spotify, DAB/FM (no amp) and standard RCA outs to connect to my amp? My idea box would also have a hard drive built in 1-2 TB of space so that I could save my ripped CDs to it and play.
