A Processor preamp is for decoding and sending the correct info to the different channels 5.1 or 7.1.
(Unless you plan on getting more speakers and more amplifiers to drive them you can get by without)
Using your 2 channel setup with LS50’s:
I would change up the source. Invest in a Oppo universal player/DAC, the BDP 105 and other models have variable volume control so I think you could hook it directly to your Red Dragon or still use the Schiit. Once you have a great source you can build from there and add to it. EXAMPLE: you could add a music server because the Oppo is a DAC already and a dam good one with USB 2.0 audio input it can be easily connected to anything! , the Oppo's sound is so good it is Stereophile rated class A (BDP105) with dual audio outs XLR and RCA connections. Did I mention it up samples (using some of the best video circuitry on the planet) all your DVD’s to 4K! Oppo makes many models for all budgets.
You could also use a PS4pro as a source it is only $400 and has digital (optical) audio outs so u can use a outboard dac then to your system pre amp , It is a great universal player, video/music streamer and with Playstation Vue u can get all ur TV shows as well.
