AMR DP-777 Advice

[steven whitton]

Just traded my Nad M51 for a AMR DP-777 will be using with Aries and wondering what will be the best connection between them,if USB then please recommend a nice USB cable that's not to expensive budget around £300,to be honest i was looking to upgrade my Nad M51 months ago but when i received my Aries femto version the improvement in sound quality from my M51 was so great i no longer felt the need to upgrade but i got a deal i just could not pass up on this well regarded Dac and since most of my listening is redbook quality it made sense to me,i have been using AES/EBU from M51 to Aries so not very clued up on USB.
