I’d stay clear of the headphone outs and Bluetooth as neither of those options are going to sound very good. Digital streaming from a quality device dedicated to the task has the potential to introduce you to some truly outstanding experiences far exceeding CD. Get the Bluesound Node. It’s easy to use, easy to setup, supports nearly everything you’ll want it to (including MQA) and won’t break the bank. Right out of the box it sounds pretty good if not a little on the dark side and if you want to take the next step you can do a dedicated DA or feed its digital to your integrated (losing the MQA if you go that route). It’s a great entry to hi res streaming and easy to sell if you decide to step up to something better.
