Total newbie question here about completing a system


Hello all: Forgive the novice nature of this, but I'm trying to help my son build out a system and I'm a bit lost. Here's what we have so far: Adcom GFA 5500 amp, Audio Research LS2 preamp, Klipsch RP-160M reference premiere bookshelf speakers (new), an old Yamaha turntable, plus a tuner and CD player that we're not certain we'll use. We seem to be missing an equalizer, correct? Also, I should note my son plans on using mostly digital (Pandora, etc.), plus some wax. Please advise on what we need to round this out. The digital feed needs to be converted, correct? Again, so sorry for the basic questions, but most of these components are inherited and I don't have enough understanding of putting this together. All wit and wisdom welcome.

Much thanks for all...this has given me a good next step in my understanding. I'll circle back with more info on the TT, but in the meantime I'm intrigued by Willemj's suggestion of "the very good and very affordable ODAC"... I'm a little unclear about the model.. Is this it? https://www.amazon.com/FiiO-E10K-Headphone-Amplifier-Black/dp/B00LP3AMC2/ref=sr_1_1?ie=UTF8&qid=1514410871&sr=8-1&keywords=ODAC
And can I assume you simply connect this to a USB port on your computer, then attach cables from line out on this unit to line in on the preamp?
thanks for this...we'll pick up the ODAC as a start.

The turntable/cartridge combo is from an old kit and is nothing special -- Yamaha Stereo Turntable TT-300U3, cardridge -- Audio Tecnica VS245LP

Would love recommendations on a phono amp.

As for cables, can I assume the normal Monoprice cables are good enough?
