I'm considering the purchase of an Arcam AVR850 for hi-fi and home cinema (priority is hi-fi). I currently run a hybrid system with AV and hi-fi amps and a Beresford switch box. I rather like my Cambridge 851A hi-fi amp as it has 2 XLR connections into my Roksan Blak CD player and Cambridge 851N streamer. My Arcam dealer suggests that the DAC on board the Roksan is good and he would go via an analogue RCA pair for this and for the 851N go via coax or optical and use the onboard DAC of the Arcam. Can anyone with experience of the Arcam AVR850 comment on the stereo performance? I've read good reviews but personal feedback will be valued. Also, I'm nervous about changing from XLR connections an analogue RCA pair as I remember how big an improvement it was when I started using balanced connections. I realise the back of an AV amp is crowded but am I sacrificing quality by using RCA connections?
