IMO, if you are having this problem with a Rogue magnum 3, which is very warm sounding (I had 1 for years), it’s both your speakers and the denon. You have no dac and the denon isn’t any good. The focals are also on the cool side of things.
start with a new source, get a good dac, the best you can afford and stream ripped or Qobuz/Tidal to see if your sound gets better. I use Roon on an external server where thousands of cds are ripped to a local ssd, and then I subscribe to Qobuz, but using Roon you just play music at it determines if it’s coming from your internal disk or from Qobuz.
If that doesn’t help in the sound quality, either get new speakers that are more neutral or get a couple of subs for the focals
