Digital Path to Complete my System

My analog system is complete - now looking at the digital side/path. I have always been a 2-channel analog guy but reluctant to dive in with $$ on the digital side as the newer/better/upgraded versions seem to be coming out yearly...if not monthly. I am currently using a Bluenode until my digital experience/knowledge is more complete and for what it does - the Bluenode is impressive! I like the convince of the digital chain but want my purchase to be one and done = not upgraded in the future. And – a MSB Technology system is not in my price range. Aurender seems to hit the sweet spot of price point, sound, bang for the buck, reputation, customer service, and build quality. Would appreciate experienced feedback for those with a complete digital chain ( streamer, DAC, clock?, & cables/interconnects) - total package under $18K...appreciate if it is a digital side you researched, own, listened to, and have settled on. My preamp, amp is set....just need the digital path! Again, something I would not need to update and add onto in the future...
