I have a Rega DAC v.1 which runs into a Naim/Rega system. I primarily listen to vinyl but want to max out my system.
I use DB poweramp for ripping and J River for file management streaming. I have a surgical grade optical line based on the low fi USB chip in the Rega. I just use my personal laptop (Toshiba), nothing fancy, for sending out the audio signal.
What sorts of software upgrades should I do? Should I move to a USB line?
