Where do I go from here?

We finally moved into a home that allows me to unbox the remnants of a system that I boxed up almost 20 years ago.  After two decades, I'd forgotten what I had until I unboxed a pair of Martin Logan Class, a pair of Acoustat 1+1s, a Robertson 6010.  At one point I owned a BAT VK-60, butsold that and an Audible Illusions preamp around  2008...a decision that I regret today.  I also uncovered new replacement panels for the CLSs.  Since this stuff has been boxed-up I've been away from audio completely.  That's about to change.  I plan to continue enjoying the CLSs and plan to return to tube tube amps.  I loved the VK-60's sound and it looks fantastic.  

My question is more about streaming.  My sense is that I get away with a streamer, subscribe to a service, and use it as my pre-amp connected to the power amps. ..  Is it that simple?  I don't want to deal with  CDs or vinyl.  I want to simplify my life.  I'm looking for feedback.  Is my plan viable?
