one box solution?

From what I read the general consensus for best sound quality was roon + HQplayer + core (to be kept in another room!) to  renderer + power supply to additional signal enhancers to DAC.  A few weeks later it's just pick up a one box server, software included.   In concept, is this accurate?   I was just going to pay for a HQplayer and though the license alone is 20% the cost of the cheapest Innuos.
