Essentially you are asking how to play digital files containedon Usb drives without the Oppo. Your Ayre becomes irrelevant here because it lacks digital inputs. I would keep the Oppo and the monitor and continue to use it-them for the usb drives and any other format that the Ayre doesn’t play (Blu Ray, SACD, whatever). If you don’t like the sound of the Oppo add an external DAC, and pick one that will enhance the sound of the Ayre
I want to dump my Oppo; but...
I'm getting an Ayre C-5xeMP and I'd like it to replace My Oppo BDP-105, assuming it performs better once I get to comparing. The problem is I've built up a sizable library on USB drives and the Ayre has no digital inputs. An outboard DAC would do for the music; but how would I navigate through the 100+ folders and their files? I don't have or want a smart phone and keeping a laptop on my knees would be a real buzzkill. Right now I use the 105 just for stereo audio and it's plugged into an old LCD monitor for navigation and set-up.
