Square one. A streamer is a highly specialized computer whose only job is to deliver the digital signal to your system. Your system, however, requires an analog signal. That's where the Digtital to Analog Converter (DAC) is necessary.
The Bluesound Node 2Ci contains both so something just under $600 is all you need to spend currently for hardware. You will feed your Node with an ethernet signal which you say you have at the ready. From the Node to your preamp you will need a pair of RCA cables and you are done. Just plug it into your preamp input labeled CD or Aux and sit back.
As a further suggestion, you might consider upgrading your phone/controller/remote from iPhone 6 to something like an iPhone Xr or an iPad Air. The larger screen might come in handy for viewing your options. As a last suggestion, I would recommend you try Qobuz. It seems more inclined toward grownups than Tidal and it does not require MQA which can limit your DAC options should you develop curiosity about how much better things can get at some point in the future.
I bought from Crutchfield where they give you 60 days to decide about your level of satisfaction, and free shipping. The unit lists for $550 but there will be tax. That's why I posted "under $600" rather than a more precise figure.
