So you're really young?
Just think about it logically. Your speakers will still connect to the amp with speaker wire. Might review this

The pre-amp would be connected to your amp with rca cables.
You'd connect digital sources like your Wiim streamer to your dac, looks like you have a choice of optical or coax so get an appropriate cable. The dac would connect to your pre-amp via rca cables to one of the analog inputs.
You'd connect your tt (using the internal phono stage) to one of the analog inputs on the pre-amp.
Since your gear isn't particularly sub friendly looks like you would use one of the pairs of SE outs on the pre-amp to connect to the L/R inputs on the sub with rca cables....
Like speaker wire, I wouldn't spend money on silly cables, just appropriate ones. Why did you change opamps?
